Water Quality Criteria Development for Iron  

Science Conference Proceedings (OSTI)

The current national water quality criterion for iron — a criterion continuous concentration of 1 mg Fe/L — was derived 25 years ago. Such ambient water quality criteria are typically derived from toxicity tests in which the reagent grade chemical is dissolved in clean laboratory water. However, due to the complexity of iron speciation in freshwater, adverse effects of iron precipitates on habitat quality, and access of organisms to food, standard toxicity assays may not adequately assess the...

Database and Analytical Tool for Air Quality in the Upper Ohio River Valley Database and Analytical Tool for Air Quality in the Upper Ohio River Valley Advanced Technology Systems, Inc. with Ohio University and Texas A&M University - Kingsville as subcontractors, will develop a state-of-the-art, scalable and robust computer application for NETL to manage the extensive data sets resulting from the DOE-sponsored ambient air monitoring programs in the upper Ohio River valley region. Efforts will be made to include, to the greatest extent possible, ambient air data collected by other agencies in the upper Ohio River valley region, such as U.S. EPA, Pennsylvania Department of Environmental Protection (PA-DEP), West Virginia Division of Environmental Protection (WV-DEP), Ohio EPA, and the Allegheny County Health Department (ACHD). Although emphasis will be placed on data collected in the upper Ohio River valley region, the computer application developed under this Agreement will be designed, to the greatest extent possible, to access data collected at NETL-sponsored ambient air monitoring sites outside the region, such as sites operated by the Tennessee Valley Authority in the Great Smoky Mountains (under DOE Interagency Agreement DE-AI26-98FT40406) and by Southern Research Institute in North Birmingham, AL (under DOE Cooperative Agreement DE-FC26-00NT40770). The data base and analytical tool development effort will also be coordinated, to the greatest extent possible, with similar tools being developed for use by U.S. EPA. This will ensure that the database and analytical tools produced under this Agreement will be readily accessible to a wide variety of stakeholders.

Mechano-freezing of the ambient water  

E-Print Network (OSTI)

Raman spectroscopy examination of the 25 deg-C water freezing under compression revealed transition from 1.35 GPa to 0.86 GPa upon ice being formed at continued volume change. The transition is associated with a slight blue shift of the high-frequency phonon (omiga_H ~ 3120 cm-1) and creation of the low-frequency phonons (Omiga_L ~ 200 cm-1). In the liquid and in the solid phase, the increased pressure softens the Omiga_H and stiffens the Omida_L, which indicates the presence of the inter-electron-pair repulsion in both liquid and solid water.

The Inhomogeneous Structure of Water at Ambient Conditions  

NLE Websites -- All DOE Office Websites (Extended Search)

The Inhomogeneous Structure of Water at The Inhomogeneous Structure of Water at Ambient Conditions The water molecule, H2O, has deceptively simple structure, but contains all the prerequisites for building complexity. The oxygen atom has a greater affinity for electrons and pulls them away from the hydrogens making them slightly positive. On the back side of molecule oxygen has a lone pair - electrons that do not assist in binding the hydrogens in the molecule, but to which the hydrogens of another water molecule can be attracted to form a so-called hydrogen bond (H-bond). Hydrogen bond is much weaker than the bonding inside water molecule, but it is still strong enough with the possibility to make from one up to four H-bonds per water molecule. The network connected by H-bonds between water molecules makes liquid water so special compared to other normal liquids with about 66 anomalies, e.g. density maximum at 4 °C and large heat capacity. The anomalies of water become extreme in the supercooled region (below freezing point), whilst they are also present at ambient conditions where most of waters' physical, chemical and biological processes of importance occur. Water at ambient conditions has traditionally been considered as a homogeneous distribution of near- tetrahedral H-bonded structures with thermal fluctuations increasing with temperature. This picture has been challenged by recent studies based on x-ray Raman (XRS), x-ray absorption spectroscopy (XAS) and x-ray emission spectroscopy (XES), suggesting two distinct local structures with tetrahedral as a minority and highly H-bond distorted asymmetrical as the majority. In particular, the proposed predominant asymmetrical structure has caused intense debate in the last years.

Projected compliance with the PM2.5 National Ambient Air Quality Standards. Final report  

SciTech Connect

In 1997, the State of Maryland had no available ambient Federal Reference Method data on particulate matter less than 2.5 microns in aerodynamic diameter (PM2.5) but did have annual ambient data for particulate matter smaller than 10 microns (PM10) at twenty-four sites. The PM10 data was analyzed in conjunction with local annual and seasonal ZIP code-level emission inventories and with speciated PM2.5 data from four nearby monitors in the IMPROVE network (located in the national parks and wilderness areas) in an effort to predict annual average and seasonal high PM2.5 concentrations at the twenty-four PM10 monitor sites operated from 1992 to 1996. All seasonal high concentrations were predicted to be below the 24-hour PM2.5 National Ambient Air Quality Standard (NAAQS) at the sites operated in Maryland between 1992 and 1996. A geographic analysis of the emission inventories was also performed to evaluate the impact of PM2.5 emissions from Maryland`s power plants on fourteen monitor locations that were predicted to have a reading exceeding the annual NAAQS for any year.

Environmental resources of selected areas of Hawaii: Climate, ambient air quality, and noise  

DOE Green Energy (OSTI)

This report has been prepared to make available and archive background scientific data and related information on climate, ambient air quality, and ambient noise levels collected during the preparation of the environmental impact statement (EIS) for Phases 3 and 4 of the Hawaii Geothermal Project (HGP) as defined by the state of Hawaii in its April 1989 proposal to Congress. The US Department of Energy (DOE) published a notice withdrawing its Notice of Intent to prepare the HGP-EIS. Since the state of Hawaii is no longer pursuing or planning to pursue the HGP, DOE considers the project to be terminated. The report presents a general description of the climate add air quality for the islands of Hawaii (henceforth referred to as Hawaii), Maui and Oahu. It also presents a literature review as baseline information on the health effects of sulfide. The scientific background data and related information is being made available for use by others in conducting future scientific research in these areas. This report describes the environmental resources present in the areas studied (i.e., the affected environment) and does not represent an assessment of environmental impacts.

Observations on a Montana water quality proposal.  

Science Conference Proceedings (OSTI)

In May 2005, a group of petitioners led by the Northern Plains Resource Council (NPRC) submitted a petition to revise water quality requirements to the Montana Board of Environmental Review (BER). Under Montana law, the BER had to consider the petition and either reject it or propose it as a new regulation. In September 2005, the BER announced proposed changes to the Montana water quality regulations. The proposal, which included almost the exact language found in the petition, was directed toward discharges of water from coal bed natural gas (CBNG) production. The key elements of the proposal included: (1) No discharges of CBNG water are allowed to Montana surface waters unless operators can demonstrate that injection to aquifers with the potential for later recovery of the water is not feasible. (2) When operators can demonstrate the injection is not feasible, the CBNG water to be discharged must meet very strict technology-based limits for multiple parameters. (3) The Montana water quality standards for the sodium adsorption ratio (SAR) and electrical conductivity (EC) would be evaluated using the 7Q10 flow (lowest 7-consecutive-day flow in a 10-year period) rather than a monthly flow that is currently used. (4) SAR and EC would be reclassified as ''harmful parameters'', thereby greatly restricting the ability for CBNG discharges to be allowed under Montana's nondegradation regulations. The proposed regulations, if adopted in their current form, are likely to substantially reduce the amount of CBNG production in Montana. The impact also extends to Wyoming CBNG production through much greater restrictions on water quality that must be met at the interstate border.

Impacts of Water Quality on Residential Water Heating Equipment  

SciTech Connect

Water heating is a ubiquitous energy use in all residential housing, accounting for 17.7% of residential energy use (EIA 2012). Today, there are many efficient water heating options available for every fuel type, from electric and gas to more unconventional fuel types like propane, solar, and fuel oil. Which water heating option is the best choice for a given household will depend on a number of factors, including average daily hot water use (total gallons per day), hot water draw patterns (close together or spread out), the hot water distribution system (compact or distributed), installation constraints (such as space, electrical service, or venting accommodations) and fuel-type availability and cost. While in general more efficient water heaters are more expensive than conventional water heating technologies, the savings in energy use and, thus, utility bills can recoup the additional upfront investment and make an efficient water heater a good investment over time in most situations, although the specific payback period for a given installation will vary widely. However, the expected lifetime of a water heater in a given installation can dramatically influence the cost effectiveness and savings potential of a water heater and should be considered, along with water use characteristics, fuel availability and cost, and specific home characteristics when selecting the optimum water heating equipment for a particular installation. This report provides recommendations for selecting and maintaining water heating equipment based on local water quality characteristics.

The water quality at nine surface water stations, eight ground water stations, and the drilling operations at the Fenton Hill Site have been studied as a measure of the environmental impact of the Los Alamos Scientific Laboratory geothermal experimental studies in the Jemez Mountains. Surface water quality in the Jemez River drainage area is affected by the quality of the inflow from thermal and mineral springs. Ground water discharges from the Cenozoic Volcanics are similar in chemical quality. Water in the main zone of saturation penetrated by test hole GT-2 is highly mineralized, whereas water in the lower section of the hole, which is in granite, contains a higher concentration of uranium.

Water quality in vicinity of Fenton Hill Site, 1975  

DOE Green Energy (OSTI)

Water quality at 9 surface water stations, 14 ground water stations, and drilling and testing operations at the Fenton Hill Site has been studied as a measure of the environmental impact on the Los Alamos Scientific Laboratory's geothermal site in the Jemez Mountains. Slight variations in the chemical quality of the water at individual stations were observed during the year. Predominant ions and total dissolved solids in the surface and ground water declined slightly in comparison to previous data. These variations in quality are not considered significant considering seasonal and annual stream flow variations. Surface water discharge records from three U.S. Geological Survey gaging stations on the Rio Guadalupe and Jemez River were analyzed to provide background data for the impact study. Direct correlations were determined between mean annual discharge at each of two stations in the upper reach of the drainage and at the station in the lower reach.

Review of Wildfire Effects on Chemical Water Quality  

SciTech Connect

The Cerro Grande Fire of May 2000 burned almost 43,000 acres of forested land within the Pajarito Plateau watershed in northern New Mexico. Runoff events after the fire were monitored and sampled by Los Alamos National Laboratory. Changes in the composition of runoff water were noted when compared to runoff water composition of the previous 20 years. In order to understand the chemical water quality changes noted in runoff water after the Cerro Grande Fire, a summary of the reported effects of fire on runoff water chemistry and on soils that contribute to runoff water chemistry was compiled. The focus of this report is chemical water quality, so it does not address changes in sediment transport or water quantity associated with fires. Within the general inorganic parameters, increases of dissolved calcium, magnesium, nitrogen, phosphorus, and potassium and pH in runoff water have been observed as a result of fire. However, the dissolved sodium, carbon, and sulfate have been observed to increase and decrease as a result of fire. Metals have been much less studied, but manganese, copper, zinc, and cesium-137 have been observed to increase as a result of fire.

In-situ X-ray photoelectron spectroscopy studies of water on metals and oxides at ambient conditions  

DOE Green Energy (OSTI)

X-ray photoelectron spectroscopy (XPS) is a powerful tool for surface and interface analysis, providing the elemental composition of surfaces and the local chemical environment of adsorbed species. Conventional XPS experiments have been limited to ultrahigh vacuum (UHV) conditions due to a short mean free path of electrons in a gas phase. The recent advances in instrumentation coupled with third-generation synchrotron radiation sources enables in-situ XPS measurements at pressures above 5 Torr. In this review, we describe the basic design of the ambient pressure XPS setup that combines differential pumping with an electrostatic focusing. We present examples of the application of in-situ XPS to studies of water adsorption on the surface of metals and oxides including Cu(110), Cu(111), TiO2(110) under environmental conditions of water vapor pressure. On all these surfaces we observe a general trend where hydroxyl groups form first, followed by molecular water adsorption. The importance of surface OH groups and their hydrogen bonding to water molecules in water adsorption on surfaces is discussed in detail.

Relationship of regional water quality to aquifer thermal energy storage  

DOE Green Energy (OSTI)

Ground-water quality and associated geologic characteristics may affect the feasibility of aquifer thermal energy storage (ATES) system development in any hydrologic region. This study sought to determine the relationship between ground-water quality parameters and the regional potential for ATES system development. Information was collected from available literature to identify chemical and physical mechanisms that could adversely affect an ATES system. Appropriate beneficiation techniques to counter these potential geochemical and lithologic problems were also identified through the literature search. Regional hydrology summaries and other sources were used in reviewing aquifers of 19 drainage regions in the US to determine generic geochemical characteristics for analysis. Numerical modeling techniques were used to perform geochemical analyses of water quality from 67 selected aquifers. Candidate water resources regions were then identified for exploration and development of ATES. This study identified six principal mechanisms by which ATES reservoir permeability may be impaired: (1) particulate plugging, (2) chemical precipitation, (3) liquid-solid reactions, (4) formation disaggregation, (5) oxidation reactions, and (6) biological activity. Specific proven countermeasures to reduce or eliminate these effects were found. Of the hydrologic regions reviewed, 10 were identified as having the characteristics necessary for ATES development: (1) Mid-Atlantic, (2) South-Atlantic Gulf, (3) Ohio, (4) Upper Mississippi, (5) Lower Mississippi, (6) Souris-Red-Rainy, (7) Missouri Basin, (8) Arkansas-White-Red, (9) Texas-Gulf, and (10) California.

Approaches to verification of two-dimensional water quality models  

DOE Green Energy (OSTI)

The verification of a water quality model is the one procedure most needed by decision making evaluating a model predictions, but is often not adequate or done at all. The results of a properly conducted verification provide the decision makers with an estimate of the uncertainty associated with model predictions. Several statistical tests are available for quantifying of the performance of a model. Six methods of verification were evaluated using an application of the BETTER two-dimensional water quality model for Chickamauga reservoir. Model predictions for ten state variables were compared to observed conditions from 1989. Spatial distributions of the verification measures showed the model predictions were generally adequate, except at a few specific locations in the reservoir. The most useful statistics were the mean standard error of the residuals. Quantifiable measures of model performance should be calculated during calibration and verification of future applications of the BETTER model. 25 refs., 5 figs., 7 tabs.

Impervious Areas: Examining the Undermining Effects on Surface Water Quality  

E-Print Network (OSTI)

This study explored the relationship between increased proportions of imperviousness in a watershed on surface water quality and examined the effectiveness of using remote sensing to systematically and accurately determine impervious surfaces. A supervised maximum likelihood algorithm was used to classify the 2008 high resolution National Agriculture Imagery Program (NAIP) imagery into six classifications. A stratified random sampling scheme was conducted to complete an accuracy assessment of the classification. The overall accuracy was 85%, and the kappa coefficient was 0.80. Additionally, field sampling and chemical analysis techniques were used to examine the relationship between impervious surfaces and water quality in a rainfall simulation parking lot study. Results indicated that day since last rain event had the most significant effect on surface water quality. Furthermore, concrete produced higher dissolved organic carbon (DOC), dissolved organic nitrogen (DON), potassium and calcium in runoff concentrations than did asphalt. Finally, a pollutant loading application model was used to estimate pollutant loadings for three watersheds using two scenarios. Results indicated that national data may overestimate annual pollutant loads by approximately 700%. This study employed original techniques and methodology to combine the extraction of impervious surfaces, utilization of local rainfall runoff data and hydrological modeling to increase planners' and scientists' awareness of using local data and remote sensing data to employ predictive hydrological modeling.

E-Print Network (OSTI)

Abstract: Consumption of bottled water is increasing worldwide. Prior research shows many consumers believe bottled water is convenient and has better taste than tap water, despite reports of a number of water quality incidents with bottled water. The authors explore the demographic and social factors associated with bottled water users in the U.S. and the relationship between bottled water use and perceptions of the quality of local water supply. They find that U.S. consumers are more likely to report bottled water as their primary drinking water source when they perceive that drinking water is not safe. Furthermore, those who give lower ratings to the quality of their ground water are more likely to regularly purchase bottle water for drinking and use bottle water as their primary drinking water source.

Water Use Efficiency in Plant Growth and Ambient Carbon Dioxide Level  

E-Print Network (OSTI)

This report examines the validity and explores the practical implications of the proposition that CO2 enrichment of the leaf environment enhances plant growth and, simultaneously decreases plant water use. A theoretical analysis of the water and carbon dioxide balance of plant leaves was made in the form of a computer program based upon known physiological facts. It predicts significant increases in water use efficiency by plants as CO is enriched, the size of the increase depending upon the external conditions. Experimental tests were conducted in an environmental simulator with stands of soybean, pepper and southern pea plants. The predictions of the model were substantially verified, with CO2 concentrations ranging from normal to six-fold normal. Although CO2 is obviously an ideal antitranspirant, the efficacy of its release in open stands is doubtful in view of plausible economic factors. Butt in enclosures this would be a different matter, and for such situations the present report gives a scientific basis for engineering and system analysis.

Real-Time Water Quality Management in the Grassland Water District  

SciTech Connect

The purpose of the research project was to advance the concept of real-time water quality management in the San Joaquin Basin by developing an application to drainage of seasonal wetlands in the Grassland Water District. Real-time water quality management is defined as the coordination of reservoir releases, return flows and river diversions to improve water quality conditions in the San Joaquin River and ensure compliance with State water quality objectives. Real-time water quality management is achieved through information exchange and cooperation between shakeholders who contribute or withdraw flow and salt load to or from the San Joaquin River. This project complements a larger scale project that was undertaken by members of the Water Quality Subcommittee of the San Joaquin River Management Program (SJRMP) and which produced forecasts of flow, salt load and San Joaquin River assimilative capacity between 1999 and 2003. These forecasts can help those entities exporting salt load to the River to develop salt load targets as a mechanism for improving compliance with salinity objectives. The mass balance model developed by this project is the decision support tool that helps to establish these salt load targets. A second important outcome of this project was the development and application of a methodology for assessing potential impacts of real-time wetland salinity management. Drawdown schedules are typically tied to weather conditions and are optimized in traditional practices to maximize food sources for over-wintering wildfowl as well as providing a biological control (through germination temperature) of undesirable weeds that compete with the more proteinaceous moist soil plants such as swamp timothy, watergrass and smartweed. This methodology combines high resolution remote sensing, ground-truthing vegetation surveys using established survey protocols and soil salinity mapping using rapid, automated electromagnetic sensor technology. This survey methodology could be complemented with biological surveys of bird use and invertebrates to produce a robust long-term monitoring strategy for habitat health and sustainability.

Optimal Operation of Large Agricultural Watersheds with Water Quality Restraints  

E-Print Network (OSTI)

Improved technology is needed for use in properly managing large agricultural watersheds. Proper watershed management means selecting land uses that are appropriate for each subarea, using erosion control measures where necessary, and applying fertilizers at rates that maximize agricultural production without polluting the environment. Watershed runoff and industrial and municipal effluents pollute streams and reservoirs. Point source pollution (industries and municipalities) can be monitored. Nonpoint-source pollution (watersheds) is widely dispersed and not easily measured. Mathematical models are needed to predict nonpoint-source pollution as affected by watershed characteristics, land use, conservation practices, chemical fertilizers, and climatic variables. Routing models are needed to determine the quality of water as it flows from nonpoint sources through streams and valleys to rivers and large reservoirs. Models are also needed to determine optimal strategies for planning land use, conservation practices, and fertilizer application to maximize agricultural production subject to water quality constraints. Three of the most important agricultural pollutants are suspended sediment, phosphorus, and nitrogen. Robinson [1971] pointed out that sediment is the greatest pollutant of water in terms of volume. Sediment also transports other pollutants, like phosphorus and nitrogen. These two elements are principally involved in lake eutrophication. Frequently algae blooms develop in nutrient-laden water and cause it to have an off-taste and an unpleasant odor. The odor of decaying plants becomes offensive; fish are killed because of reduced dissolved oxygen in the water, and recreation is deterred. The objective of this research was to develop models for use in managing large agricultural watersheds to obtain maximum agricultural production and to maintain water quality standards. The models were designed to: 1. Simulate daily runoff, and sediment, phosphorus, and nitrogen yields from small watersheds (areas land owners and operators) for planning land use, fertilizer application, and conservation practices on subwatersheds. 4. Determine the optimal strategy for each subwatershed to maximize agricultural production for the entire watershed subject to water quality constraints. Generally, water-quality models are developed by adding chemical modeling components to existing runoff and sediment models because runoff and sediment provide transportation for chemicals. Several conceptual models for predicting chemical yields from small watersheds have been presented [Crawford and Donigian, 1973; Donigian and Crawford, 1976; Frere, et al., 1975; Hagin and Amberger, 1974; Kling, 1974; Johnson and Straub, 1971]. However, these models are not applicable to large watersheds because they have no routing mechanism. For this reason, runoff, sediment, and nutrient models were refined and developed here for application to large watersheds. Probably, the most widely used and accepted model for predicting runoff volume is the Soil Conservation Service (SCS) curve number system [U.S. Soil Conservation Service, 1972]. The SCS model was modified by adding a soil-moisture-index accounting procedure [Williams and Laseur, 1976]. The modified water yield model is considerably more accurate than the original SCS model. On a watershed near Riesel, Texas, the modified model explained 95% of the variation in monthly runoff as compared with 65% for the original model. The water-yield model was refined here by replacing the climatic index (lake evaporation) with daily consumptive water use for individual crops.

Impact of alfalfa on soil and water quality  

DOE Green Energy (OSTI)

Dominance of row crop agriculture in rolling landscapes of western and Southwestern Minnesota is identified as a primary, non-point source of sediments and associated pollutants reaching the Minnesota River. Currently as a biomass energy project, alfalfa is being promoted in western Minnesota to harvest the leaves for animal feed and stems to generate electricity. As a perennial, leguminous crop grown with minimum inputs, introduction of alfalfa in row cropped lands has potential to improve both in-situ soil productivity and downstream water quality. A field study was initiated in 1996 to compare the volume of runoff and pollutants coming from alfalfa an com-soybean fields in western Minnesota. Two pair of alfalfa and corn-soybean watersheds were instrumented at Morris in the Fall of 1996 to measure rainfall, runoff, and sample water for sediment load, phosphorus, nitrogen, biochemical oxygen demand, and chemical oxygen demand. Simulated rainfall-runoff experiments were conducted on an existing crop rotation - input management study plots at Lamberton to evaluate soil quality effects of the inclusion of alfalfa in a corn-soybean rotation under manure and fertilization management schemes. Alfalfa soil water use as a function of frequency of harvest was also monitored at Morris to evaluate the effect of cutting schedule on soil water use. During the growing season of 1997, alfalfa under a two-cut management scheme used about 25-mm (an inch) more soil water than under a three-cut schedule. The mean differences between the treatments were not significant. The conclusions drawn in this report come from analysis of data collected during one winter-summer hydrologic and crop management cycle. Continued observations through a period of at least 3-5 years is recommended to improve the instrumentation robustness and discern the variability due to climate, soil, and crop management factors.

Quality and Membrane Treatability of the Lake Houston Water Supply  

E-Print Network (OSTI)

Currently, sections of Harris and Montgomery counties located North and Northeast of Houston use groundwater almost exclusively. These areas have witnessed substantial population growth and associated increases in water demand. In 1999 approximately 60% of potable water in Houston and its adjoining communities was produced from surface water. The remaining approximately 40% was derived from groundwater. However, the "Subsidence District" which is the authority responsible for granting groundwater permits has mandated that groundwater use needs to be decreased to 20% within the next few years so as to limit subsidence. Pipelines are not available to distribute purified water from the existing surface water treatment plants located in the South and East of Houston to the Northern areas that actually require additional water. Because Lake Houston is located in the geographical area of interest and is a surface water source, the City of Houston is interested in developing it for its future water needs. Additionally, a favorable hydraulic gradient exists from the Lake to the proposed service areas in Harris and Montgomery counties. Federal regulations such as the Stage II of the Disinfectant/Disinfection By-Products Rule (1) and the Enhanced Surface Water Treatment Rule (2) are expected to be promulgated in the near future. These rules are anticipated to introduce more stringent maximum contaminant levels (MCLs) for total trihalomethanes (THMs) and haloacetic acids (HAAs), possibly introduce new MCLs for individual species of THMs and HAAs, reduce turbidity levels, and enhance inactivation/removal requirements for Cryptosporidium. (Cryptosporidium was the causative protozoan for the more than 400,000 cases of acute gastrointestinal disease in Milwaukee, WI in March 1993.) The treatment processes in the City of Houston's existing water purification plants are not expected to be sufficient in meeting these anticipated regulations. Therefore, both regulatory requirements and engineering considerations point towards Lake Houston as an attractive surface water source for the next water purification plant to supply potable water to the City and its adjoining communities. However, water quality in Lake Houston can be characterized as being poor with high concentrations of turbidity, color, total organic carbon (TOC), nutrients such as phosphorus and nitrogen, etc. (3). Pressure-driven membrane processes can be employed as effective barriers against a wide range of contaminants including particles, turbidity, protozoan cysts and oocysts, bacteria, viruses, color, organic carbon, disinfection by-product (DBP) precursors, and dissolved metals. Additionally, microfiltration (MF) and ultrafiltration (UF) pretreatment may be necessary to reduce fouling rates and increase chemical cleaning intervals during surface water nanofiltration (NF) (4). Therefore, an integrated membrane system employing MF or UF pretreatment to NF is expected to be an important treatment candidate for Lake Houston water. Nanofiltration (NF) membranes typically operate at pressures less than 100 psi and are capable of high rejections of natural organic matter (NOM) and precursors to disinfection by-products (DBP) including trihalomethanes (THMs) and haloacetic acids (HAAs) (5-8), many of which are suspected carcinogens, mutagens, or teratogens.

Biofuels and water quality: challenges and opportunities for simulation modeling  

SciTech Connect

Quantification of the various impacts of biofuel feedstock production on hydrology and water quality is complex. Mathematical models can be used to efficiently evaluate various what if scenarios related to biofeedstock production and their impacts on hydrology and water quality at various spatial and temporal scales. Currently available models, although having the potential to serve such purposes, have many limitations. In this paper, we review the strengths and weaknesses of such models in light of short- and long term biofeedstock production scenarios. The representation of processes in the currently available models and how these processes need to be modified to fully evaluate various complex biofeedstock production scenarios are discussed. Similarly, issues related to availability of data that are needed to parameterize and evaluate these models are presented. We have presented a vision for the development of decision support tools and ecosystem services that can be used to make watershed management decisions to minimize any potentially adverse environmental impacts while meeting biofeedstock demands. We also discuss a case study of biofeedstock impact simulation in relation to watershed management policy implications for various state and federal agencies in the USA.

Lake Whitney Comprehensive Water Quality Assessment, Phase 1B- Physical and Biological Assessment (USDOE)  

Science Conference Proceedings (OSTI)

Baylor University Center for Reservoir and Aquatic Systems Research (CRASR) has conducted a phased, comprehensive evaluation of Lake Whitney to determine its suitability for use as a regional water supply reservoir. The area along the Interstate 35 corridor between Dallas / Fort Worth Metroplex and the Waco / Temple Centroplex represents one of the fastest growth areas in the State of Texas and reliable water supplies are critical to sustainable growth. Lake Whitney is situated midway between these two metropolitan areas. Currently, the City of Whitney as well as all of Bosque and Hill counties obtain their potable water from the Trinity Sands aquifer. Additionally, parts of the adjoining McLennan and Burleson counties utilize the Trinity sands aquifer system as a supplement to their surface water supplies. Population growth coupled with increasing demands on this aquifer system in both the Metroplex and Centroplex have resulted in a rapid depletion of groundwater in these rural areas. The Lake Whitney reservoir represents both a potentially local and regional solution for an area experiencing high levels of growth. Because of the large scope of this project as well as the local, regional and national implications, we have designed a multifaceted approach that will lead to the solution of numerous issues related to the feasibility of using Lake Whitney as a water resource to the region. Phase IA (USEPA, QAPP Study Elements 1-4) of this research focused on the physical limnology of the reservoir (bathymetry and fine scale salinity determination) and develops hydrodynamic watershed and reservoir models to evaluate how salinity would be expected to change with varying hydrologic and climatic factors. To this end, we implemented a basic water quality modeling program in collaboration with the Texas Parks and Wildlife Department and the Texas Commission on Environmental Quality to add to the developing long-term database on Lake Whitney. Finally, we conducted an initial assessment of knowledge of watershed and water quality related issues by local residents and stakeholders of Lake Whitney and design an intervention educational program to address any deficiencies discovered. Phase IA was funded primarily from EPA Cooperative Agreement X7-9769 8901-0. Phase IC (USEPA, QAPP Study Element 5) of this research focused on the ambient toxicity of the reservoir with respect to periodic blooms of golden algae. Phase IC was funded primarily from Cooperative Agreement EM-96638001. Phase 1B (USDOE, Study Elements 6-11) complemented work being done via EPA funding on study elements 1-5 and added five new study elements: 6) Salinity Transport in the Brazos Watershed to Lake Whitney; 7) Bacterial Assessment; 8) Organic Contaminant Analysis on Lake Whitney; 9) Plankton Photosynthesis; 10) Lake Whitney Resident Knowledge Assessment; and 11) Engineering Scoping Perspective: Recommendations for Use.

Evaluation of an Absorption Heat Pump to Mitigate Plant Capacity Reduction Due to Ambient Temperature Rise for an Air-Cooled Ammonia and Water Cycle: Preprint  

DOE Green Energy (OSTI)

Air-cooled geothermal plants suffer substantial decreases in generating capacity at increased ambient temperatures. As the ambient temperature rises by 50 F above a design value of 50 F, at low brine-resource temperatures, the decrease in generating capacity can be more than 50%. This decrease is caused primarily by increased condenser pressure. Using mixed-working fluids has recently drawn considerable attention for use in power cycles. Such cycles are more readily amenable to use of absorption ''heat pumps.'' For a system that uses ammonia and water as the mixed-working fluid, this paper evaluates using an absorption heat pump to reduce condenser backpressure. At high ambient temperatures, part of the turbine exhaust vapor is absorbed into a circulating mixed stream in an absorber in series with the main condenser. This steam is pumped up to a higher pressure and heated to strip the excess vapor, which is recondensed using an additional air-cooled condenser. The operating conditions are chosen to reconstitute this condensate back to the same concentration as drawn from the original system. We analyzed two power plants of nominal 1-megawatt capacity. The design resource temperatures were 250 F and 300 F. Ambient temperature was allowed to rise from a design value of 50 F to 100 F. The analyses indicate that using an absorption heat pump is feasible. For the 300 F resource, an increased brine flow of 30% resulted in a net power increase of 21%. For the 250 F resource, the increase was smaller. However, these results are highly plant- and equipment-specific because evaluations must be carried out at off-design conditions for the condenser. Such studies should be carried out for specific power plants that suffer most from increased ambient temperatures.

Water Quality Hydrology of Lands Receiving Farm Animal Wastes  

E-Print Network (OSTI)

A significant pollution potential from cattle manure has developed as a result of the cattle feeding industry progressing to large, high density feeding operations. Two major potential sources of pollution from beef feedlots is storm runoff and solid waste (manure). The objectives of this research were to determine the characteristics of storm runoff from a beef feedlot, to determine the nitrogen transformations and ammonia volatilization from soils receiving large manure applications, to determine the chemical quality of surface runoff and groundwater from plots receiving large manure applications, to evaluate techniques of deep plowing large amounts of manure into the soil, and to determine the crop quality and yields on field plots receiving large manure application rates. Feedlot runoff was found to carry large amounts of chemical elements. The concentrations of chemical elements did not vary with size and intensity of rainstorm as much as by differences in topography of the watersheds. More ammonia was volatilized from limed soil columns than unlimed but an unexplained decrease in total nitrogen of 10 to 20 percent occurred in the unlimed and limed soil columns, respectively. A 30-in. moldboard plowing 30 to 36-in. deep can safely turn under up to 900 tons/acre of manure and not create a major surface water pollution problem. An increase of chemical elements in the groundwater occurred during the first year and then were reduced to initial values during the second year. No N03 pollution of groundwater occurred. Crops can be effectively grown on land receiving up to 900 tons/acre of manure. Peak yields will not be obtained the first year after plowing the 900 tons under, but yields will increase the second and third years.

CONSTRUCTED WETLAND TREATMENT SYSTEMS FOR WATER QUALITY IMPROVEMENT  

SciTech Connect

The Savannah River National Laboratory implemented a constructed wetland treatment system (CWTS) in 2000 to treat industrial discharge and stormwater from the Laboratory area. The industrial discharge volume is 3,030 m{sup 3} per day with elevated toxicity and metals (copper, zinc and mercury). The CWTS was identified as the best treatment option based on performance, capital and continuing cost, and schedule. A key factor for this natural system approach was the long-term binding capacity of heavy metals (especially copper, lead, and zinc) in the organic matter and sediments. The design required that the wetland treat the average daily discharge volume and be able to handle 83,280 m{sup 3} of stormwater runoff in a 24 hour period. The design allowed all water flow within the system to be driven entirely by gravity. The CWTS for A-01 outfall is composed of eight one-acre wetland cells connected in pairs and planted with giant bulrush to provide continuous organic matter input to the system. The retention basin was designed to hold stormwater flow and to allow controlled discharge to the wetland. The system became operational in October of 2000 and is the first wetland treatment system permitted by South Carolina DHEC for removal of metals. Because of the exceptional performance of the A-01 CWTS, the same strategy was used to improve water quality of the H-02 outfall that receives discharge and stormwater from the Tritium Area of SRS. The primary contaminants in this outfall were also copper and zinc. The design for this second system required that the wetland treat the average discharge volume of 415 m{sup 3} per day, and be able to handle 9,690 m{sup 3} of stormwater runoff in a 24 hour period. This allowed the building of a system much smaller than the A-01 CWTS. The system became operational in July 2007. Metal removal has been excellent since water flow through the treatment systems began, and performance improved with the maturation of the vegetation during the first season of growth of each system. Sediment samples after the first and third years of operation indicated that copper was being bound in the sediments very rapidly after entering the treatment system. The design of the system encourages low redox and sulfide production in the sediments. The objective is to stabilize metals, including mercury, as sulfide compounds in the sediments. Costs for maintenance and operation of the systems are minimal, consisting primarily of ensuring that the pipes are not clogged and that water is flowing through the system. The treatment cost per thousand gallons is many times less than conventional wastewater treatment facilities. Life expectancy and function of the biological system is based on the life of the engineering aspects and not the wetland ecology.

Water quality in the vicinity of Fenton Hill, 1987 and 1988. [Fenton Hill site  

DOE Green Energy (OSTI)

Water-quality data have been collected since 1974 from established surface- and ground-water stations at, and in the vicinity of, Fenton Hill (site of the Laboratory's Hot Dry Rock Geothermal Project). The site is located on the southwest edge of the Valles Caldera in the Jemez Mountains. To determine the chemical quality of water, data were collected in 1987 and 1988 from 13 surface-water stations and 19 ground-water stations. The classification of the water quality is made on the basis of predominated ions and total dissolved solids. There are four classifications of surface water (sodium and chloride, calcium and bicarbonate, calcium and sulfate, and sodium and bicarbonate) and three classifications of ground water (sodium and chloride, calcium and bicarbonate, and sodium and bicarbonate). Variations in the chemical quality of the surface and ground water in 1987 and 1988 are apparent when data are compared with each other and with previous analyses. These variations are not considered significant, as they are in the range of normal seasonal changes. Cumulative production since 1976 from the supply well at Fenton Hill has been about 63 {times} 10{sup 6} gal, with a decline in the water level of the well of about 14 ft, or about 1.4 ft/yr. The aquifer penetrated by the well is still capable of reliable supply to the site for a number of years, based on past production. The quality of water from the well has deteriorated slightly; however, the water quality is in compliance with drinking water standards. The effects of discharge from the storage ponds into an adjacent canyon have been monitored by trace metal analyses of vegetation and soil. The study indicates minimal effects, which will be undetectable in a few years if there are no further releases of effluents into the canyon. 19 refs., 6 figs., 3 tabs.

South Asia Water Resources Workshop: An effort to promote water quality data sharing in South Asia  

SciTech Connect

To promote cooperation in South Asia on environmental research, an international working group comprised of participants from Bangladesh, India, Nepal, Pakistan, Sri Lanka, and the US convened at the Soaltee Hotel in Kathmandu, Nepal, September 12 to 14, 1999. The workshop was sponsored in part by the Cooperative Monitoring Center (CMC) at Sandia National Laboratories in Albuquerque, New Mexico, through funding provided by the Department of Energy (DOE) Office of Nonproliferation and National Security. The CMC promotes collaborations among scientists and researchers in regions throughout the world as a means of achieving common regional security objectives. In the long term, the workshop organizers and participants are interested in the significance of regional information sharing as a means to build confidence and reduce conflict. The intermediate interests of the group focus on activities that might eventually foster regional management of some aspects of water resources utilization. The immediate purpose of the workshop was to begin the implementation phase of a project to collect and share water quality information at a number of river and coastal estuary locations throughout the region. The workshop participants achieved four objectives: (1) gaining a better understanding of the partner organizations involved; (2) garnering the support of existing regional organizations promoting environmental cooperation in South Asia; (3) identifying sites within the region at which data is to be collected; and (4) instituting a data and information collection and sharing process.

Water adsorption, solvation and deliquescence of alkali halide thin films on SiO2 studied by ambient pressure X-ray photoelectron spectroscopy  

Science Conference Proceedings (OSTI)

The adsorption of water on KBr thin films evaporated onto SiO2 was investigated as a function of relative humidity (RH) by ambient pressure X-ray photoelectron spectroscopy. At 30percent RH adsorbed water reaches a coverage of approximately one monolayer. As the humidity continues to increase, the coverage of water remains constant or increases very slowly until 60percent RH, followed by a rapid increase up to 100percent RH. At low RH a significant number of the Br atoms are lost due to irradiation damage. With increasing humidity solvation increases ion mobility and gives rise to a partial recovery of the Br/K ratio. Above 60percent RH the increase of the Br/K ratio accelerates. Above the deliquescence point (85percent RH), the thickness of the water layer continues to increase and reaches more than three layers near saturation. The enhancement of the Br/K ratio at this stage is roughly a factor 2.3 on a 0.5 nm KBr film, indicating a strong preferential segregation of Br ions to the surface of the thin saline solution on SiO2.

Aquatic macroinvertebrates and water quality of Sandia Canyon, Los Alamos National Laboratory, November 1993--October 1994  

SciTech Connect

The Ecological Studies Team (EST) of ESH-20 at Los Alamos National Laboratory (LANL) has collected samples from the stream within Sandia Canyon since the summer of 1990. These field studies gather water quality measurements and collect aquatic macroinvertebrates from permanent sampling sites. Reports by Bennett (1994) and Cross (1994) discuss previous EST aquatic studies in Sandia Canyon. This report updates and expands those findings. EST collected water quality data and aquatic macroinvertebrates at five permanent stations within the canyon from November 1993 through October 1994. The two upstream stations are located below outfalls that discharge industrial and sanitary waste effluent into the stream, thereby maintaining year-round flow. Some water quality parameters are different at the first three stations from those expected of natural streams in the area, indicating degraded water quality due to effluent discharges. The aquatic habitat at the upper stations has also been degraded by sedimentation and channelization. The macroinvertebrate communities at these stations are characterized by low diversities and unstable communities. In contrast, the two downstream stations appear to be in a zone of recovery, where water quality parameters more closely resemble those found in natural streams of the area. The two lower stations have increased macroinvertebrate diversity and stable communities, further indications of downstream water quality improvement.

Water quality in the vicinity of Fenton Hill. Progress report 1981 and 1982  

DOE Green Energy (OSTI)

As part of a continuing program of environmental studies, water quality data have been collected from established surface and ground water stations and from ponds and pond discharges at Fenton Hill Site located in the Jemez Mountains. Most of these stations were established in 1973, and water quality data have been collected since that time. There have been slight variations in the chemical quality of water from the surface and ground water locations; however, these variations are within normal seasonal fluctuations. The discharge from ponds at Fenton Hill infiltrates into canyon alluvium within 400 m of the site. Monitoring surface and spring discharge downgradient from the ponds failed to detect any effects resulting from water released from the ponds. Total dissolved solids and calcium have increased in water from well FH-1, which furnishes the water supply for the site. This increase is caused by the decreasing water level in the well resulting in yield from beds with a slightly different quality than has been found in previous years.

NM WAIDS: A PRODUCED WATER QUALITY AND INFRASTRUCTURE GIS DATABASE FOR NEW MEXICO OIL PRODUCERS  

SciTech Connect

The New Mexico Water and Infrastructure Data System (NM WAIDS) seeks to alleviate a number of produced water-related issues in southeast New Mexico. The project calls for the design and implementation of a Geographical Information System (GIS) and integral tools that will provide operators and regulators with necessary data and useful information to help them make management and regulatory decisions. The major components of this system are: (1) Databases on produced water quality, cultural and groundwater data, oil pipeline and infrastructure data, and corrosion information. (2) A web site capable of displaying produced water and infrastructure data in a GIS or accessing some of the data by text-based queries. (3) A fuzzy logic-based, site risk assessment tool that can be used to assess the seriousness of a spill of produced water. (4) A corrosion management toolkit that will provide operators with data and information on produced waters that will aid them in deciding how to address corrosion issues. The various parts of NM WAIDS will be integrated into a website with a user-friendly interface that will provide access to previously difficult-to-obtain data and information. Primary attention during the first six months of this project was focused on creating the water quality databases for produced water and surface water, along with collecting of corrosion information and building parts of the corrosion toolkit. Work on the project to date includes: (1) Creation of a water quality database for produced water analyses. The database was compiled from a variety of sources and currently has over 7000 entries for New Mexico. (2) Creation of a web-based data entry system for the water quality database. This system allows a user to view, enter, or edit data from a web page rather than having to directly access the database. (3) Creation of a semi-automated data capturing system for use with standard water quality analysis forms. This system improves the accuracy and speed of water quality data entry. (4) Acquisition of ground water data from the New Mexico State Engineer's office, including chloride content and TDS (Total Dissolved Solids) for over 30,000 data points in southeast New Mexico. (5) Creation of a web-based scale prediction tool, again with a web-based interface, that uses two common scaling indices to predict the likelihood of scaling. This prediction tool can either run from user input data, or the user can select samples from the water analysis database. (6) Creation of depth-to-groundwater maps for the study area. (7) Analysis of water quality data by formation. (8) Continuation of efforts to collect produced water quality information from operators in the southeast New Mexico area. (9) Qualitative assessment of produced water from various formations regarding corrosivity. (10) Efforts at corrosion education in the region through operator visits. Future work on this project will include: (1) Development of an integrated web and GIS interface for all the information collected in this effort. (2) Continued development of a fuzzy logic spill risk assessment tool that was initially developed prior to this project. Improvements will include addition of parameters found to be significant in determining the impact of a brine spill at a specific site. (3) Compilation of both hard copy and online corrosion toolkit material.

Imaging with ambient noise  

Science Conference Proceedings (OSTI)

Recent developments in seismology, ultrasonics, and underwater acoustics have led to a radical change in the way scientists think about ambient noise--the diffuse waves generated by pressure fluctuations in the atmosphere, the scattering of water waves in the ocean, and any number of other sources that pervade our world. Because diffuse waves consist of the superposition of waves propagating in all directions, they appear to be chaotic and random. That appearance notwithstanding, diffuse waves carry information about the medium through which they propagate.

Water quality data have been collected since 1974 from established surface and groundwater stations at and in the vicinity of Fenton Hill (Hot Dry Rock Geothermal Demonstration Site) located in the Jemez Mountains. This is part of a continued program of environmental studies. There has been a slight variation in chemical quality of water from the surface and groundwater stations; however, these variations are within normal seasonal fluctuations. Water supply at the site is pumped from the aquifer in the Abiquiu Tuff. Cumulative production from 1976 through 1984 has been 41.5 x 10/sup 6/ gal. The water level in the supply well declined from 365 ft in 1976 to 379 ft in 1984.

Water Quality: 2007 Data, BPA-51; Preliminary Report, January 26, 2009.  

DOE Green Energy (OSTI)

Print Out No.1 presents a listing of the initial data. The variables included were: SITE, REP, NH4, NO2{_}3, SRP, TDP, TN, TP, and JULIAN , representing site code, replication number, ammonia nitrogen, nitrate and nitrite nitrogen, soluble reactive phosphorus, total dissolved phosphorus, total nitrogen, total phosphorus, and Julian date, respectively. All values for nitrogen, phosphorus, and carbon variables are recorded as {micro}g/L. The 2007 water quality data received by SCS required considerable manipulation and data management prior to analysis. If it is anticipated that water quality data received by SCS in the future will be of the same format, the time to carry out the necessary reformatting of the data should be taken into consideration. The levels of SRP from water quality data of previous years were often below detection limits. The data from 2007 showed elevated levels for this and other responses. This pattern was seemingly unrelated to nutrient addition treatments, however, as they appeared consistently across the study area. The river fertilization program was begun in 2005. Because the procedures for detection of nutrients and metals are quite sensitive, SCS recommends that any future water quality samples taken on, or close to, the dates of fertilizer application be carried out with the utmost care to avoid contamination issues.

Water quality in the vicinity of Fenton Hill, 1985 and 1986: Progress report  

DOE Green Energy (OSTI)

Water quality data have been collected since 1974 from established surface and groundwater stations at and in the vicinity of Fenton Hill (Hot Dry Rock Geothermal Demonstration Site) located in the Jemez Mountains. This is part of a continuing program of environmental studies. Data on chemical quality of water were determined for samples collected from 13 surface water and 19 groundwater stations in 1985 and 1986. There were slight variations in the chemical quality of the ground and surface water in 1985 and 1986 as compared with previous analyses; however, these variations are within normal seasonal fluctuations. Chemical uptake in soil, roots, and foliage is monitored in the canyon, which receives intermittent effluent release of water from tests in the geothermal circulation loop and occasional fluids from drilling operations. The chemical concentrations found in soil, roots, and vegetation as the result of effluent release have shown a decrease in concentration down-canyon and also have decreased in concentration with time since the larger releases that took place in the late 1970s and early 1980s. 18 refs., 7 figs., 9 tabs.

Use of compost filter bermsfor sediment trapping: primary focus on water quality and structural stability  

E-Print Network (OSTI)

Runoff from road construction and maintenance sites is responsible for erosion and deposition of sediments in the receiving water bodies. In addition to soil particles from erosion, runoff also transports other pollutants such as rubber, toxic metals, automobile fluids, car exhausts (which settle with the rain), pesticides, fertilizers, and other debris. Compost has been used effectively as a valuable soil amendment to aid plant growth. Berms (mounds) of compost placed at the top or bottom of steep slopes can be used to slow the velocity of water and provide additional protection for receiving waters. However, a downside of the application of composted organic material is the potential degradation of runoff water quality. Overloading with nitrogen and phosphorus causes eutrophication, which reduces the suitability of waterways for beneficial uses. A field testing of the berms coupled with a laboratory analysis of the testing water will provide a basis for the impact of the compost berms on the runoff water quality. The study of the impact of compost on the runoff water quality was investigated. The objective of this study was to evaluate the performance of berms made from various materials such as dairy manure compost, yard waste compost and composted bio-solids mixed with wood chips in a ratio of 50:50 on the runoff water quality, as well as, the sediment removal efficiencies. Field tests were performed on the berms to simulate conventional rainfall runoff and the tested water was collected as time-weighted samples and analyzed in the laboratory. Several variables were investigated during this study. Results of this investigation demonstrated that the effectiveness of this application was hampered by the structural instability of the berm. A 100% failure rate was observed in the berms tested. Optimum performance was observed in yard waste compost berms, which introduced the least amount of contaminants into the water. However, some masking effect could be present due to berm failures. In fact, the actual sediment removal by the berms could not be determined. The study of compost filter berms showed some evidence of the existence of first flush effect.

Education Program for Improved Water Quality in Copano Bay Final Report  

E-Print Network (OSTI)

The Copano Bay watershed covers approximately 1.4 million acres encompassing portions of Karnes, Bee, Goliad, Refugio, San Patricio and Aransas counties. Copano Bay and its main tributaries, the Mission and Aransas rivers, were placed on the Texas Commission on Environmental Quality (TCEQ) 303(d) list in 1998 due to levels of bacteria that exceed water quality standards established to protect oyster waters use. A Total Maximum Daily Load (TMDL) program was initiated in September 2003 to identify and assess sources of these bacteria. The Center for Research in Water Resources at the University of Texas at Austin (UT CRWR) was funded by TCEQ to conduct computer-based modeling to determine the bacterial loading and reductions necessary to attain water quality standards. Subsequently Texas A&M University-Corpus Christi (TAMU-CC) conducted bacterial source tracking (BST) with funding from Texas General Land Office (TGLO) and the Coastal Bend Bays and Estuaries Program (CBBEP) to determine actual sources of bacteria. Due to the findings of the initial efforts of the TMDL and concerns voiced by stakeholders in the watershed, Texas AgriLife Extension Service was awarded a Clean Water Act § 319(h) Nonpoint Source Grant from the Texas State Soil and Water Conservation Board (TSSWCB) and the U.S. Environmental Protection Agency. The overall goal of this project was to improve water quality in Copano Bay and its tributaries by increasing awareness of water quality issues throughout the watershed. This increased awareness was to be accomplished by providing education and demonstrations for land and livestock owners in the watershed on best management practices (BMPs) to decrease or prevent bacteria from entering waterways. Through creation of a project website, 52 educational programs, and nine one-on-one consultations over the span of the project, we have reached 5,408 residents in and around the Copano Bay watershed. Additionally, through this project all data collected for the initial TMDL efforts was re-evaluated and findings were presented in the “Task 2 Report.” Project members developed a curriculum for horse owners, “A Guide to Good Horsekeeping” that addressed BMPs specific to horse operations. Land and livestock owners who had already implemented BMPs or were interested in implementing BMPs were given a participation certificate.

Water Quality Trends in the Entiat River Subbasin: Final 2008 Annual Report.  

DOE Green Energy (OSTI)

The ISEMP program monitors the status and trend of water quality elements that may affect restoration project effectiveness in the Entiat subbasin. As part of this effort, the PNW Research Station (PNW) measures, analyzes and interprets temporal trends in natural stream water pH, dissolved oxygen, specific conductivity and temperature. The Entiat River is currently on the Clean Water Act 303(d) list for pH exceedence, and there is insufficient information to determine the spatial and temporal extent or potential causes of this exceedence. In the spring 2008, PNW redeployed data-logging, multiparameter probes at four locations in the Entiat subbasin to measure water quality parameters, focusing on pH. This resumed previous data collection that was interrupted by river ice in early December 2007. Instruments were again removed from the river in early December 2008. This annual report covers the period from December 2007 through December 2008. The highest pH values occurred during the low-flow period from midsummer through the following midspring then dropped sharply during the annual snowmelt runoff period from late spring through early summer. Water temperature began rapidly increasing during the receding limb of the annual snowmelt hydrograph. Highest mean monthly temperatures occurred in July and August, while instantaneous maxima occurred during the period July-September. Dissolved oxygen reached its lowest levels during the period of highest water temperature in July-September. Specific conductivity remained very low at all sites throughout the year.

Quality control of chemical and isotopic analyses of geothermal water samples  

DOE Green Energy (OSTI)

Chemical and isotopic analyses of geothermal water samples must meet certain levels of accuracy and reliability to be useful for identifying geochemical processes in hydrothermal systems. Quality control is largely a concern for the analytical laboratory, but the geochemist or reservoir engineer using the chemical data must also be concerned with analytical quality. To test accuracy and reliability of analyses available from laboratories, splits of seven water samples were sent to four stable-isotope laboratories, and splits of five water samples were sent to four chemical laboratories. The analyses of each sample were compared among laboratories, and the differences in analyses were evaluated using criteria developed for this comparison. Isotopic compositions were considered reliable if they deviated from mean values by less than 2{per_thousand}, for hydrogen and by less than 0.15{per_thousand}, for oxygen. Concentrations of each chemical component were considered reliable if they differed from mean values by less than 10%. Chemical analyses were examined for internal consistency by calculating the error in ionic charge balance and the error between ionic charge and electrical conductivity. To be considered internally consistent, chemical analyses must have less than 5% error in charge balance and less than 10% error in conductivity balance. Three isotope laboratories gave consistent compositions of all samples. No chemical laboratory gave consistent analyses of all samples. Recommendations are made that provide the user of isotopic and chemical data with the ability to better evaluate the quality of analyses.

Okanogan Subbasin Water Quality and Quantity Report for Anadromous Fish in 2006.  

DOE Green Energy (OSTI)

Fish need water of sufficient quality and quantity in order to survive and reproduce. The list of primary water quality indicators appropriate for monitoring of anadromous fish, as identified by the Upper Columbia Monitoring Strategy, includes: discharge, temperature, dissolved oxygen, pH, turbidity, conductivity, nitrogen, phosphorus and ammonia. The Colville Tribes Fish and Wildlife Department began evaluating these water quality indicators in 2005 and this report represents data collected from October 1, 2005 through September 30, 2006. We collected empirical status and trend data from various sources to evaluate each water quality indicator along the main stem Okanogan and Similkameen Rivers along with several tributary streams. Each water quality indicator was evaluated based upon potential impacts to salmonid survival or productivity. Specific conductance levels and all nutrient indicators remained at levels acceptable for growth, survival, and reproduction of salmon and steelhead. These indicators were also considered of marginal value for monitoring environmental conditions related to salmonids within the Okanogan subbasin. However, discharge, temperature, turbidity, dissolved oxygen and pH in that order represent the water quality indicators that are most useful for monitoring watershed health and habitat changes and will help to evaluate threats or changes related to salmon and steelhead restoration and recovery. On the Okanogan River minimum flows have decreased over the last 12 years at a rate of -28.3CFS/year as measured near the town of Malott, WA. This trend is not beneficial for salmonid production and efforts to reverse this trend should be strongly encouraged. Turbidity levels in Bonaparte and Omak Creek were a concern because they had the highest monthly average readings. Major upland disturbance in the Bonaparte Creek watershed has occurred for decades and agricultural practices within the riparian areas along this creek have lead to major channel incision and bank instability. High sediment loads continue to threaten Omak and Bonaparte sub-watersheds. Major rehabilitation efforts are needed within these sub-watersheds to improve salmonid habitats. We found that for the past 12 years dissolved oxygen levels have been on a slightly downward trend during summer/fall Chinook egg incubation. Dissolved oxygen readings in early October, for summer/fall Chinook and from June through early July for summer steelhead can occasionally drop to the range from 8 to 10 mg/L and therefore warrant continued monitoring. Levels of pH represent an indicator that has little monitoring value throughout most of the subbasin. The Similkameen River drainage showed dramatic annual changes in the mean pH values and a declining trend for pH thus warranting continued monitoring. Average daily temperatures, in 2006, exceeded 25 C for eight days in July in the Okanogan River at Malott. Due to increased warm water temperatures, delays in migration have increased at a rate of 1.82 days per year over the last 10 years. Increases in water temperature can be linked to many anthropogenic activities. Increasing water temperatures within the Okanogan River watershed represent the single most limiting factor facing salmonids in main-stem habitats.

Silvicultural Activities in Relation to Water Quality in Texas: An Assesment of Potential Problems and Solutions  

E-Print Network (OSTI)

Southern forests are expected to supply a large portion of the Nation's future timber requirement. Projected demands on southern forests continue to exceed allowable cut. As an outgrowth of this demand, intensive management of pine forests enabled the South to produce 45 percent of the Nation's timber harvest in 1970 (USDA, Forest Service, 1973). The Southern Forest Resource Analysis Committee (1969) stated that, if projected timber needs of the year 2000 are to be met, at least ten million acres of bare or poorly stocked land must be planted with pine by 1985 and another twenty million acres converted from low-grade hardwoods to pine. The challenge facing forestry in the South is how to meet this increased demand and maintain an acceptable forest environment in the face of increased taxes, rising labor and equipment costs and predicted petroleum shortages. Undisturbed forests are generally recognized as primary sources of high quality water. Although the Federal Water Pollution Control Act Amendments of 1972 (Public Law No. 92-500) make pollution from forest practices increasingly more important, the effects of these practices on water quality are not known for East Texas. The quality of streamflow from forested watersheds fluctuates constantly in response to natural stress, and can be influenced greatly by man's activities. Forest management practices can potentially influence the following water quality parameters: (1) sediment, (2) nutrients, (3) temperature, (4) dissolved oxygen/organic matter, and (5) introduced chemicals. It must be realized from the onset that sediment due to geologic erosion is a natural component of fresh water streams and that high concentrations may have occurred naturally for short periods due to perturbations in the ecosystem such as wildfires. Sediment is not necessarily a pollutant and only becomes one when it can be demonstrated that it is exceeding natural levels and is interfering with the beneficial use of water. A certain amount of sediment and nutrients are needed in Gulf Bays and Estuaries to maintain their productivity (Mathewson and Minter, 1976; Diener, 1964; Ketchum, 1967). Texas does not have a stream water quality standard for sediment and due to the complexities involved will probably not develop one. Thus, sediment as used in this report, becomes important: (1) as a carrier of plant nutrients and forest chemicals, and (2) in that practices which reduce sediment loss will usually reduce nutrient, organic matter and introduced chemical losses and prevent water temperature increases, as well. This report is the result of an interagency contract between Texas Department of Water Resources, Texas Agricultural Experiment Station and Texas Water Resources Institute to: (1) develop an overview of commercial forests and forestry operations in Texas, (2) identify, describe and characterize control strategies for nonpoint sources of pollution from silvicultural activities, and (3) develop and demonstrate a methodology for selecting control strategies in given problem situations. The following topics are covered: (1) an overview of forestry in East Texas, (2) silvicultural practices and nonpoint sources of pollution, (3) control strategies, (4) methodology for the selection of control strategies, (5) institutional aspects of controlling silvicultural nonpoint source pollution, (6) ongoing research and research needs, and (7) hydrology of East Texas. It is important to recognize that this report does not specify that nonpoint pollution from forestlands in East Texas is a problem. Likewise, the report does not set pollution control goals or criteria that should be met by a control plan, since this is the responsibility of the State. In areas where a potential nonpoint pollution problem exists; the suggested control strategies should be useful in selecting control measures that are appropriate to the special conditions imposed by differences in climate, soil, topography, and forest practice.

Aquatic macroinvertebrates and water quality of Sandia Canyon, Los Alamos National Laboratory, 1995  

Science Conference Proceedings (OSTI)

The Biology Team of ESH-20 (the Ecology Group) at Los Alamos National Laboratory (LANL) has collected samples from the stream within Sandia Canyon since the summer of 1990. These field studies measure water quality parameters and collect aquatic macroinvertebrates from sampling sites within the upper canyon stream. Reports by Bennett and Cross discuss previous aquatic studies in Sandia Canyon. This report updates and expands the previous findings. The Biology Team collected water quality data and aquatic macroinvertebrates monthly at three sampling stations within Sandia Canyon in 1995. The two upstream stations occur near a cattail (Typha latifolia) dominated marsh downstream from outfalls that discharge industrial and sanitary waste effluent into the stream, thereby maintaining year-round flow. The third station is approximately 1.5 miles downstream from the outfalls within a mixed conifer forest. All water chemistry parameters measured in Sandia Canyon during 1995 fell within acceptable State limits and scored in the {open_quotes}good{close_quotes} or {open_quotes}excellent{close_quotes} ranges when compared to an Environmental Quality Index. However, aquatic macroinvertebrates habitats have been degraded by widespread erosion, channelization, loss of wetlands due to deposition and stream lowering, scour, limited acceptable substrates, LANL releases and spills, and other stressors. Macroinvertebrate communities at all the stations had low diversities, low densities, and erratic numbers of individuals. These results indicate that although the stream possesses acceptable water chemistry, it has reduced biotic potential. The best developed aquatic community occurs at the sampling station with the best habitat and whose downstream location partially mitigates the effects of upstream impairments.

Determining an optimal sampling frequency for measuring bulk temporal changes in ground-water quality  

Science Conference Proceedings (OSTI)

In the Data Quality Objectives (DQO) process, statistical methods are used to determine an optimal sampling and analysis plan. When the DQO decision rule for instituting remedial actions is based on a critical change in water quality, the monitoring program design must ensure that this change can be detected and measured with a specified confidence. Usually the focus is on the change at a single monitoring location and the process is limited to addressing the uncertainty inherent in the analytical methods and the variability at that location. However, new strategies that permit ranking the waste sites and prioritizing remedial activities require the means for assessing overall changes for small regions over time, where both spatial and temporal variability exist and where the uncertainty associated with these variations far exceeds measurement error. Two new methods for assessing these overall changes have been developed and are demonstrated by application to a waste disposal site in Oak Ridge, Tennessee. These methods incorporate historical data where available and allow the user to either test the statistical significance of a linear trend or of an annual change compared to a baseline year for a group of water quality wells.

Water Quality Sampling Locations Along the Shoreline of the Columbia River, Hanford Site, Washington  

Science Conference Proceedings (OSTI)

As environmental monitoring evolved on the Hanford Site, several different conventions were used to name or describe location information for various sampling sites along the Hanford Reach of the Columbia River. These methods range from handwritten descriptions in field notebooks to the use of modern electronic surveying equipment, such as Global Positioning System receivers. These diverse methods resulted in inconsistent archiving of analytical results in various electronic databases and published reports because of multiple names being used for the same site and inaccurate position data. This document provides listings of sampling sites that are associated with groundwater and river water sampling. The report identifies names and locations for sites associated with sampling: (a) near-river groundwater using aquifer sampling tubes; (b) riverbank springs and springs areas; (c) pore water collected from riverbed sediment; and (d) Columbia River water. Included in the listings are historical names used for a particular site and the best available geographic coordinates for the site, as of 2009. In an effort to create more consistency in the descriptive names used for water quality sampling sites, a naming convention is proposed in this document. The convention assumes that a unique identifier is assigned to each site that is monitored and that this identifier serves electronic database management requirements. The descriptive name is assigned for the convenience of the subsequent data user. As the historical database is used more intensively, this document may be revised as a consequence of discovering potential errors and also because of a need to gain consensus on the proposed naming convention for some water quality monitoring sites.

Analysis of a flow metering device for low-quality steam-water flows. Final report  

DOE Green Energy (OSTI)

The goal of this project is to investigate the potential of the meter configuration consisting of a sharp-edged contraction section followed by an extended length of constant area duct and finally a diffuser section for pressure recovery. This and two other configurations were tested. These configurations and the reasons underlying their selection are described and discussed. It is concluded that Murdock's correlation for steam/water flow through orifices and sudden contraction sections at low qualities is invalid and the metering scheme based on it is inoperative. (MHR)

On Managing Texas Rural Water Supply Systems: A Socioeconomic Analysis and Quality Evaluation  

E-Print Network (OSTI)

Research Objectives The study reported here is aimed at evaluating the effectiveness of nonprofit, rural water supply corporations or water systems (hereafter referred to as RWSs) in Texas from a sociological perspective. Specifically, the study has attempted to: 1. Provide an overview of the organizational structure and functioning of RWSs, identifying their existing as well as emerging needs, problems, and suggested solutions. It explores socioeconomic characteristics and patterns of RWSs in Texas. It outlines a history of state and federal regulations and practices through which these systems are structured and actually function. 2. Evaluate the quality and effectiveness of the management of selected RWSs located in different geographical regions of Texas. The evaluation of effectiveness of systems is accomplished through a systematic set of procedures and techniques. These procedures are tested for reliability and validity through empirical data. In addition, the differential levels of program effectiveness of RWSs are elaborated upon by correlating them with relevant socioeconomic variables. 3. Indicate policy and research implications of data for dealing with the future of rural water systems. Expected Contributions The rural populations in the U.S. started experiencing steady increases during the 1970s and early 1980s (Goodwin et al., 1984). Although the rural population growth at the national level showed a few differential trends during mid to late 1980s (Figures 3 and 4 in Appendix A), the state of Texas registered a population influx in many nonmetropolitan areas during the last decade (U.S.D.A., 1990: 11). Overall, a significant portion of Texas' population still resides in rural areas (Texas Department of Water Resources, 1984: 7). However, it appears that a larger number of studies have focused on water-management related problems and issues for urban areas than those for rural communities in Texas (e.g., Knudson, 1986; Meier and Thorton, 1973; Murdock et al., 1988; Texas Department of Water Resources, 1985; Texas Water Development Board, 1990;1 and U.S. Army Corps of Engineers, 1989). While rural water problems have been examined carefully in several parts of the country, we could not find a single study in Texas systematically examining water-related needs and issues confronting rural communities. The need to study rural water supply has become even more important now because of the challenge faced by small community systems in complying with the provisions of the 1986 Safe Drinking Water Act (SDWA). These small systems, with their limited customer and revenue bases, will face formidable expense in installing new water treatment methods (Jensen, 1990; Long and Stukenberg, 1987: 38; Texas Water Development Board, 1990: 14). The present study is a timely probe into the phenomena of rural water supply. The study is aimed at developing and using a methodology to evaluate the program effectiveness of RWSs. In recent years, interest has mounted for employing the research techniques of social sciences in efforts to assess the effectiveness of public programs. The 1970s and 1980s, decades of rapid-paced growth of RWSs in Texas and elsewhere, were marked by the proliferation of public expenditures. The study uses a set of indicators to identify effectiveness and efficiency of rural water projects. Such measures for analysis and appraisal of these projects may contribute to more informed and intelligent planning for the future. The study is also expected to provide a critical probe and insight into an evaluation methodology that may be used in future studies investigating public programs. To this end, the research reported here is exploratory in nature and may set grounds for more critical studies in the area. The study, for example, develops a baseline against which to measure future changes and trend in rural water supplies in Texas as well as in other parts of the country.

West Village Community: Quality Management Processes and Preliminary Heat Pump Water Heater Performance  

Science Conference Proceedings (OSTI)

West Village, a multi-use project underway at the University of California Davis, represents a ground-breaking sustainable community incorporating energy efficiency measures and on-site renewable generation to achieve community-level Zero Net Energy (ZNE) goals. The project when complete will provide housing for students, faculty, and staff with a vision to minimize the community's impact on energy use by reducing building energy use, providing on-site generation, and encouraging alternative forms of transportation. This focus of this research is on the 192 student apartments that were completed in 2011 under Phase I of the West Village multi-year project. The numerous aggressive energy efficiency measures implemented result in estimated source energy savings of 37% over the B10 Benchmark. There are two primary objectives of this research. The first is to evaluate performance and efficiency of the central heat pump water heaters as a strategy to provide efficient electric water heating for net-zero all-electric buildings and where natural gas is not available on site. In addition, effectiveness of the quality assurance and quality control processes implemented to ensure proper system commissioning and to meet program participation requirements is evaluated. Recommendations for improvements that could improve successful implementation for large-scale, high performance communities are identified.

Influence of chemical characterization of oil shale solids on understanding water quality impacts  

SciTech Connect

Synfuels technologies will yield products and effluents that are a function of the raw material being processed and the process variables. Chemical and mineralogic characterization of solids generated in synfuels production provide valuable insight into health and environmental impacts associated with synfuels processing (coal liquefaction or gasification and shale oil extraction). This report deals with considerations relating to leachate generation from solid wastes, but the suggested research approach is applicable to understanding the nature and extent of all effluents from synfuels operations. Solid characterization studies of one raw shale core and two spent shale cores from Occidental Oil Shale, Inc.'s Logan Wash site are described. These data are used to determine the effect of processing on the shale solids and also to evaluate a variety of water quality issues associated with in situ processing. The importance of solid characterization studies in developing an understanding of effluent composition and behavior and subsequently defining environmental impacts is described.

Advanced, Environmentally Friendly Hydroelectric Turbines for the Restoration of Fish and Water Quality  

DOE Green Energy (OSTI)

Hydroelectric power contributes about 10 percent of the electrical energy generated in the United States, and nearly 20 percent of the world?s electrical energy. The contribution of hydroelectric generation has declined in recent years, often as a consequence of environmental concerns centering around (1) restriction of upstream and downstream fish passage by the dam, and (2) alteration of water quality and river flows by the impoundment. The Advanced Hydropower Turbine System (AHTS) Program of the U.S. Department of Energy is developing turbine technology which would help to maximize global hydropower resources while minimizing adverse environmental effects. Major technical goals for the Program are (1) the reduction of mortality among turbine-passed fish to 2 percent or less, compared to current levels ranging up to 30 percent or greater; and (2) development of aerating turbines that would ensure that water discharged from reservoirs has a dissolved oxygen concentration of at least 6 mg/L. These advanced, ?environmentally friendly? turbines would be suitable both for new hydropower installations and for retrofitting at existing dams. Several new turbine designs that have been he AHTS program are described.

Effects of Biochar Recycling on Switchgrass Growth and Soil and Water Quality in Bioenergy Production Systems  

E-Print Network (OSTI)

Intensive biomass production in emerging bioenergy systems could increase nonpoint-source sediment and nutrient losses and impair surface and groundwater quality. Recycling biochar, a charcoal byproduct from pyrolysis of biomass, provides potential sources of mineral nutrients and organic carbon for sustaining biomass productivity and preserving soil and water. Yet, research is needed to verify that recycling of pyrolysis biochars will enhance crop growth and soil and environmental quality similar to black carbon or biochar derived from burning of biomass in tropical or Terra Preta soils. The experimental design of this study consisted of 3 replications and four biochar rates (0, 4, 16, and 64 Mg ha-1) incorporated in both a sandy loam and clay soil with and without fertilizer sources of N, P, and K. The sandy loam and clay soils were studied in separate experiments within a set of 24 box lysimeters seeded with switchgrass. Simulated rain was applied at 50 percent and 100 percent establishment of switchgrass for each soil type. Runoff and leachate were collected and analyzed for total and dissolved N, P, K and organic C. After the second rain event, each soil type and the accumulated switchgrass was sampled and analyzed. In the Boonville soil, biochar applied at 64 Mg ha-1 decreased switchgrass emergence from 42 percent to 14 percent when compared to soil alone. In the Burleson soil, 64 Mg ha-1 biochar had no effect (P > 0.05) on biomass production or leaf area index (LAI). Fertilizer N, P, and K had no effect (P > 0.05) on switchgrass emergence for either soil, but did increase (P biochar increased (P biochar receiving supplemental N, P, and K fertilizer also resulted in greater runoff concentrations of DRP. Emergence tests under increased heat showed electrical conductivities of soil-water solutions to be as high as 600 microS cm-1, even after biochar was washed with acetone and water to remove residual oils and tars and soluble salts. Increasing biochar rates decreased soil bulk density and increased pH and SOC in the 0- to 5-cm depth of soil. As a result of high nutrient recovery during pyrolysis (58 percent of total N, 86 percent of total P and 101 percent of total K), high rates of biochar applied at 64 Mg ha-1 increased mass losses of TN, TP, and TK from both soils. Yet, the mass balance of nutrients showed a surplus of N, P, and K at 64 Mg ha-1 biochar, which suggests some nutrient inputs are not plant available and remain in soil. Careful management of biochar, especially at high rates with these high nutrient contents, is critical when trying to improve soil fertility while protecting water quality.

Water Quality Trends in the Entiat River Subbasin: Final Annual Report to BPA and NOAA Fisheries, 2008.  

DOE Green Energy (OSTI)

The Integrated Status and Effectiveness Monitoring Project (ISEMP) program monitors the status and trend of water quality elements that may affect restoration project effectiveness in the Entiat subbasin. As part of this effort, the PNW Research Station (PNW) measures, analyzes and interprets temporal trends in natural stream water pH, dissolved oxygen, specific conductance and temperature. The Entiat River is currently on the Clean Water Act 303(d) list for pH exceedence, and there is insufficient information to determine the spatial and temporal extent or potential causes of this exceedence. In the late spring 2007, PNW deployed data-logging, multiparameter probes at four locations in the Entiat subbasin to measure water quality parameters, focusing on pH. Data collection was seasonally interrupted by river ice in early December. Daily average pH did not exceed the water quality standard of 8.5 at any of the measurements sites. However, instantaneous values did exceed this standard near the mouth of the Entiat River during late summer-fall period. This suggested that in the lowest portion of the river peaks in pH may be occurring because of photosynthesis caused by high rates of periphyton productivity in response to increased sunlight, temperature, and possible nutrient enrichment. Conversely, dissolved oxygen reached annual low levels during this same late summer-fall period, in part because of increased water temperatures and increased biochemical oxygen demand.

Synthesis of gold nano-particles in a microfluidic platform for water quality monitoring applications  

E-Print Network (OSTI)

A microfluidic lab-on-a-chip (LOC) device for in-situ synthesis of gold nano-particles was developed. The long term goal is to develop a portable hand-held diagnostic platform for monitoring water quality (e.g., detecting metal ion pollutants). The LOC consists of micro-chambers housing different reagents and samples that feed to a common reaction chamber. The reaction products are delivered to several waste chambers in a pre-defined sequence to enable reagents/ samples to flow into and out of the reaction chamber. Passive flow actuation is obtained by capillary driven flow (wicking) and dissolvable microstructures called ‘salt pillars’. The LOC does not require any external power source for actuation and the passive microvalves enable flow actuation at predefined intervals. The LOC and the dissolvable microstructures are fabricated using a combination of photolithography and soft lithography techniques. Experiments were conducted to demonstrate the variation in the valve actuation time with respect to valve position and geometric parameters. Subsequently, analytical models were developed using one dimensional linear diffusion theory. The analytical models were in good agreement with the experimental data. The microvalves were developed using various salts: polyethylene glycol, sodium chloride and sodium acetate. Synthesized in-situ in our experiments, gold nano-particles exhibit specific colorimetric and optical properties due to the surface plasmon resonance effect. These stabilized mono-disperse gold nano-particles can be coated with bio-molecular recognition motifs on their surfaces. A colorimetric peptide assay was thus developed using the intrinsic property of noble metal nano-particles. The LOC device was further developed on a paper microfluidics platform. This platform was tested successfully for synthesis of gold nano-particles using a peptide assay and using passive salt-bridge microvalves. This study proves the feasibility of a LOC device that utilizes peptide assay for synthesis of gold nano-particles in-situ. It could be highly significant in a simple portable water quality monitoring platform.

Design and evaluation of a two-phase turbine for low quality steam--water mixtures  

DOE Green Energy (OSTI)

A new two-phase turbine was designed and built for testing in the laboratory, using a low quality steam-water mixture as a working fluid. The measured performance compares well with performance predictions of a numerical model of the expander. Details of the selection of the type of expander are given. The design of an experimental expander for use in a clean two-phase flow laboratory experiment and the development of a numerical model for performance analysis and extrapolations are described. Experiments including static cascade performance with two-phase fluid, disk friction and windage measurements, and two-phase performance measurements of the experimental expander are reported. Comparisons of the numerical model and experimental results, and the prediction of the performance of an advanced design, indicating how performance improvements can be achieved, are also included. An engine efficiency of 23 percent for a single-nozzle test was measured. Full admission performance, based upon the numerical model and achievable nozzle thrust coefficients indicate that an engine efficiency of between 38 and 48 percent can be realized with present technology. If maximum liquid removal loss is assumed, this performance range is predicted to be 38 to 41 percent. Droplet size reduction and the development and implementation of enhanced two-phase flow analysis techniques should make it possible to achieve the research goal of 70 percent engine efficiency.

NETL: Ambient Monitoring - Steubenville Comprehensive Air Monitoring  

NLE Websites -- All DOE Office Websites (Extended Search)

Steubenville Comprehensive Air Monitoring Project (SCAMP) Steubenville Comprehensive Air Monitoring Project (SCAMP) The National Ambient Air Quality Standards for airborne fine particles (PM2.5) are based on the mass of PM2.5 measured at outdoor monitoring stations; however, most people spend the majority of their time indoors. In order to fully understand the relationship between ambient PM2.5 and human health effects, it is important to define how ambient PM2.5 concentrations and compositions compare to those actually breathed by humans during normal daily activities. The objective of SCAMP is to measure the concentrations of PM2.5 and other potential air pollutants at ambient monitoring stations in and around Steubenville, OH, and relate them to the pollutant concentrations in air that is actually breathed by people living in the area. Steubenville was chosen by DOE for this study because of the ability to integrate its results with those of the UORVP, and also because Steubenville was one of the six cities where correlations between ambient PM2.5 mass and adverse health effects had been noted. These correlations had been cited by EPA as one of the primary justifications for its 1997 ambient PM2.5 standards. Complete characterization of the relationships between ambient PM2.5 and human exposure, including the chemical components of PM2.5 at various locations, will provide a comprehensive database for use in subsequent epidemiological studies, long-range transport studies, and State Implementation Program development. CONSOL Energy is the primary performer of SCAMP, and will provide the necessary coordination and data integration between the various components of the study.

Ground Water Quality and Riparian Enhancement Projects in Sherman County, Oregon; Coordination and Technical Assistance, 2003-2004 Annual Report.  

DOE Green Energy (OSTI)

This project was designed to provide technical assistance and project coordination to producers in Sherman County for on the ground water quality and riparian enhancement projects. This is accomplished utilizing the USDA Conservation Reserve Enhancement Program (CREP) in addition to other grant monies to translate the personnel funds in this project to on the ground projects. Two technicians and one watershed council coordinator are funded, either wholly or in part, by funds from this grant. The project area encompasses the whole of Sherman County which is bordered almost entirely by streams providing habitat or migration corridors for endangered fish species including steelhead and Chinook salmon. Of those four streams that comprise Sherman County's boundaries, three are listed on the DEQ 303(d) list of water quality limited streams for exceeding summer temperature limits. Only one stream in the interior of Sherman County is 303(d) listed for temperatures, but is the largest watershed in the County. Temperatures in streams are directly affected by the amount of solar radiation allowed to reach the surface of the water. Practices designed to improve bank-side vegetation, such as the CREP program, will counteract the solar heating of those water quality listed streams, benefiting endangered stocks. CREP and water quality projects are promoted and coordinated with local landowners through locally-led watershed councils. Funding from BPA provides a portion of the salary for a watershed council coordinator who acts to disseminate water quality and USDA program information directly to landowners through watershed council activities. The watershed coordinator acts to educate landowners in water quality and riparian management issues and to secure funds for the implementation of on the ground water quality projects. Actual project implementation is carried out by the two technicians funded by this project. Technicians in Sherman County, in cooperation with the USDA Natural Resources Conservation Service, assist landowners in developing Resource Management Systems (RMS) that address resource concerns in a specified land unit. These RMS plans are developed using a nine step planning process that acts to balance natural resource issues with economic and social needs. Soil, Water, Air, Plants, Animals, and Human resource concerns are the core focus in developing a framework for improving the efficiency and effectiveness of conservation activities in a given planning unit, while working within the guidelines set forth by the National Environmental Policy Act (NEPA), Clean Water Act (CWA), Endangered Species Act (ESA), Magnuson-Stevens Act (MSA), National Historic Preservation Act (NHPA), and other federal, state, and local laws. Implementation of this project has provided technical and implementation assistance for numerous on the ground projects, including over 50 WASCBs, several thousand feet of terraces, numerous spring developments, fencing, 7 implemented CREP contracts, and the development of 8 additional CREP projects slated for enrollment at the beginning of FY '05. Within the past contract year in Sherman County, 589.4 acres of CREP have been enrolled protecting 30.8 miles of riparian habitat. In addition to the increase in on the ground projects, coordination and outreach to solicit conservation projects in Sherman County has increased due to the additional staffing provided by BPA funds. As a result there is an abundance of potential conservation projects for water quality and riparian management improvement. With the sustained availability of coordination and technical assistance provided through this grant, BPA personnel funds will translate to a much higher dollar figure applied on the ground. This project has been very successful in keeping up with the demand for conservation projects within Sherman County.

A water quality assessment of the import of turfgrass sod grown with composted dairy manure into a suburban watershed  

E-Print Network (OSTI)

Concentrated animal feeding operations (CAFOs) have caused water quality concerns in many rural watersheds, sometimes forcing the State of Texas to conduct Total Maximum Daily Load (TMDL) assessments of stream nutrients such as nitrogen (N) and phosphorus (P). One suggested Best Management Practice (BMP) is the export of phosphorus (P) through turfgrass sod produced with composted dairy manure from an impaired rural watershed to an urban watershed. The manure-grown sod releases P slowly and would not require additional P fertilizer for up to 20 years in the receiving watershed. This would eliminate P application to the sod and improve the water quality of urban streams. The Soil and Water Assessment Tool (SWAT) was used to model a typical suburban watershed that would receive the transplanted sod. The objective of the modeling was to determine the water quality changes due to the import of sod transplanted from turf fields and grown with composted dairy manure. The SWAT model was calibrated to simulate historical flow and sediment and nutrient loading to Mary's Creek. The total P stream loading to Mary's Creek was lower when manure-grown sod was imported instead of commercial sod grown with inorganic fertilizers. Yet, flow, sediment yield, and total N yield increased equally for both cases at the watershed outlet. The SWAT simulations indicate that a turfgrass BMP can be used effectively to import manure P into an urban watershed and reduce in-stream P levels when compared to sod grown with inorganic fertilizers.

Identification of tire leachate toxicants and a risk assessment of water quality effects using tire reefs in canals  

Science Conference Proceedings (OSTI)

Cover is important to aquatic habitat and fisheries often try to improve habitats by addition of natural and artificial material to improve cover diversity and complexity. Habitat-improvement programs range from submerging used Christmas trees to more complex programs. Used automobile tires have been employed in the large scale construction of reefs and fish attractors in marine environments and to a lesser extent in freshwater and have been recognized as a durable, inexpensive and long-lasting material benefiting fishery communities. Recent studies by the U.S. Bureau of Reclamation have quantified the importance of tire reefs to enhancing freshwater canal fisheries in the southwestern United States. These studies have demonstrated that fishes and aquatic macroinvertebrates are attracted to these structures, increasing species diversity, densities and biomass where reefs are placed in canals. However, the use of tire reefs in aquatic environments which have relatively small volumes compared to marine or reservoir environments has raised water quality concerns. Effects of tires on water quality have not typically been studied in the past because of the obvious presence of fishes and other aquatic organisms that make use of tire reefs; the implication being that tires are inert and non-toxic. Little information on effects of tires on water quality is in the literature. Stone demonstrated that tire exposure had no detrimental effects on two species of marine fish while results of Kellough's freshwater tests were inconclusive, but suggested that some factor in tire leachate was toxic to rainbow trout (Oncorhynchus mykiss). Nozaka et al. found no harmful substances leached from tire material soaked in fresh water. Because there are few data on toxicity associated with tires, this became the focus of our study. Toxicity Identification Evaluation (TIE) procedures developed by the EPA were used to evaluate water quality impacted by tires. 17 refs., 4 figs.

Real-Time Water Quality Monitoring and Habitat Assessment in theSan Luis National Wildlife Refuge  

SciTech Connect

The project report describes a two year experiment to control wetland drainage to the San Joaquin River of California from the San Luis National Wildlife Refuge using a decision support system for real-time water quality management. This system required the installation and operation of one inlet and three drainage flow and water quality monitoring stations which allowed a simple mass balance model to be developed of the seasonally managed wetlands in the study area. Remote sensing methods were developed to document long-term trends in wetland moist soil vegetation and soil salinity in response to management options such as delaying the initiation of seasonal wetland drainage. These environmental management tools provide wetland managers with some of the tools necessary to improve salinity conditions in the San Joaquin River and improve compliance with State mandated salinity objectives without inflicting long-term harm on the wild fowl habitat resource.

Assessment of Dissolved Oxygen Mitigation at Hydropower Dams Using an Integrated Hydrodynamic/Water Quality/Fish Growth Model  

DOE Green Energy (OSTI)

Dissolved oxygen (DO) in rivers is a common environmental problem associated with hydropower projects. Approximately 40% of all FERC-licensed projects have requirements to monitor and/or mitigate downstream DO conditions. Most forms of mitigation for increasing DO in dam tailwaters are fairly expensive. One area of research of the Department of Energy's Hydropower Program is the development of advanced turbines that improve downstream water quality and have other environmental benefits. There is great interest in being able to predict the benefits of these modifications prior to committing to the cost of new equipment. In the case of turbine replacement or modification, there is a need for methods that allow us to accurately extrapolate the benefits derived from one or two turbines with better design to the replacement or modification of all turbines at a site. The main objective of our study was to demonstrate a modeling approach that integrates the effects of flow and water quality dynamics with fish bioenergetics to predict DO mitigation effectiveness over long river segments downstream of hydropower dams. We were particularly interested in demonstrating the incremental value of including a fish growth model as a measure of biological response. The models applied are a suite of tools (RMS4 modeling system) originally developed by the Tennessee Valley Authority for simulating hydrodynamics (ADYN model), water quality (RQUAL model), and fish growth (FISH model) as influenced by DO, temperature, and available food base. We parameterized a model for a 26-mile reach of the Caney Fork River (Tennessee) below Center Hill Dam to assess how improvements in DO at the dam discharge would affect water quality and fish growth throughout the river. We simulated different types of mitigation (i.e., at the turbine and in the reservoir forebay) and different levels of improvement. The model application successfully demonstrates how a modeling approach like this one can be used to assess whether a prescribed mitigation is likely to meet intended objectives from both a water quality and a biological resource perspective. These techniques can be used to assess the tradeoffs between hydropower operations, power generation, and environmental quality.

A reaction-based river/stream water quality model Part I: Model development and numerical schemes  

SciTech Connect

This paper presents the conceptual and mathematical development of a numerical model of sediment and reactive chemical transport in river/streams. The distribution of mobile suspended sediments and immobile bed sediments is controlled by hydrologic transport as well as erosion and deposition processes. The fate and transport of water quality constituents involving a variety of chemical and physical processes is mathematically described by a system of reaction equations for immobile constituents and advective-dispersive-reactive transport equations for constituents. To circumvent stiffness associated with equilibrium reactions, matrix decomposition is performed via Gauss-Jordan column reduction. After matrix decomposition, the system of water quality constituent reactive transport equations is transformed into a set of thermodynamic equations representing equilibrium reactions and a set of transport equations involving no equilibrium reactions. The decoupling of equilibrium and kinetic reactions enables robust numerical integration of the partial differential equations for non-equilibrium-variables. Solving non-equilibrium-variable transport equations instead of individual water quality constituent transport equations also reduces the number of PDEs. A variety of numerical methods are investigated for solving the mixed differential and algebraic equations. Two verification examples are compared with analytical solutions to demonstrate the correctness of the code and to illustrate the importance of employing application-dependent numerical methods to solve specific problems.

Raft River monitor well potentiometric head responses and water quality as related to the conceptual ground-water flow system  

DOE Green Energy (OSTI)

Ground-water monitoring near the Raft River site was initiated in 1974 by the IDWR. This effort consisted of semiannual chemical sampling of 22 irrigation wells near the Raft River geothermal development area. This program yielded useful baseline chemical data; however, several problems were inherent. For example, access to water pumped from the wells is limited to the irrigation season (April through September). All the wells are not continuously pumped; thus, some wells that are sampled one season cannot be sampled the next. In addition, information on well construction, completion, and production is often unreliable or not available. These data are to be supplemented by establishing a series of monitor wells in the proposed geothermal withdrawal and injection area. These wells were to be located and designed to provide data necessary for evaluating and predicting the impact of geothermal development on the Shallow Aquifer system.

Summary report on water quality, sediment and water chemistry data for water and sediment samples collected from source areas to Melton Hill and Watts Bar reservoirs  

Science Conference Proceedings (OSTI)

Contamination of surface water and sediments in the Clinch River and Watts Bar Reservoir (CR/WBR) system as a result of past and present activities by the US Department of Energy (DOE) on the Oak Ridge Reservation (ORR) and also activities by non-ORR facilities are being studied by the Clinch River Environmental Restoration Program (CR-ERP). Previous studies have documented the presence of heavy metals, organics, and radionuclides in the sediments of reservoirs in the vicinity. In support of the CR-ERP, during the summer of 1991, TVA collected and evaluated water and sediment samples from swimming areas and municipal water intakes on Watts Bar Reservoir, Melton Hill Reservoir (which is considered part of the Clinch River and Watts Bar Reservoir System), and Norris Reservoir, which was considered a source of less-contaminated reference or background data. Results of this study indicated that the levels of contamination in the samples from the Watts Bar and Melton Hill Reservoir sites did not pose a threat to human health. Despite the numerous studies, until the current work documented by this report, relatively few sediment or water samples had been collected by the CR-ERP in the immediate vicinity of contaminant point sources. This work focused on water and sediment samples taken from points immediately downstream from suspected effluent point sources both on and off the ORR. In August and September, 1994, TVA sampled surface water and sediment at twelve locations in Melton Hill and Watts Bar Reservoirs. Eleven of the sampling sites were selected based on existence of pollutant discharge permits, known locations of hazardous waste sites, and knowledge of past practices. The twelfth sample site was selected as a relatively less contaminated reference site for comparison purposes.

Water quality impacts from mining in the Black Hills, South Dakota, USA  

Science Conference Proceedings (OSTI)

The focus of this research was to determine if abandoned mines constitute a major environmental hazard in the Black Hills. Many abandoned gold mines in the Black Hills contribute acid and heavy metals to streams. In some areas of sulfide mineralization local impacts are severe, but in most areas the impacts are small because most ore deposits consist of small quartz veins with few sulfides. Pegmatite mines appear to have negligible effects on water due to the insoluble nature of pegmatite minerals. Uranium mines in the southern Black Hills contribute some radioactivity to surface water, but he impact is limited because of the dry climate and lack of runoff in that area. 26 refs.

Utilization of the upper Houston Ship Channel by fish and macroinvertebrates with respect to water quality trends  

E-Print Network (OSTI)

Nektonic utilization of the upper Houston Ship Channel (HSC) was assessed through characterization of species composition, abundance and community structure of finfish and macroinvertebrate populations. Impact of basic water quality trends on utilization was evaluated. seine, gillnet and revolving screen collections from two deep-water and six shoreline sampling stations in upper HSC stream segments 1006 (downstream) and 1007 (upstream) during May 1988 through July 1989 yielded 33,042 nektonic organisms comprising 84 taxa. Spatial and temporal trends in catch statistics, species diversity, and hydrological variables were assessed for each sampling gear type. Seasonal composition by dominant taxa was determined and effect of temperature, salinity and dissolved oxygen on catch statistics examined. Mean surface (shoreline) water temperature and dissolved oxygen levels were similar between segments and followed expected seasonal trends. Mean bottom dissolved oxygen levels in segment 1007 during May through September were consistently 1 to 1.5 mg/l lower than segment 1006 and exhibited hypoxic conditions. Significantly greater catch and biomass were observed in segment 1007 as compared to those of segment 1006. Species diversity and number of taxa were comparable between segments. Distinct reductions in catch, number of taxa and species diversity characterized winter seine collections in segment 1006. Surface water temperatures appeared to exert the greatest hydrological influence on shoreline catch statistics. Revolving screen catches were greatest in Segment 1007 during November through March when bottom dissolved oxygen levels peaked and water temperatures ebbed. Significantly reduced catches in segment 1007 during May through October coincided with highest water temperatures and near-anoxic dissolved oxygen levels. By contrast, catch statistics from segment 1006 were highest during summer and early fall when mean bottom temperature and dissolved oxygen levels were highest and lowest, respectively. Cumulative number of taxa was highest in both segments during winter. HSC segment 1006 maintains healthy shoreline and bottom nekton communities year-round. Low dissolved oxygen in bottom waters restrict nekton utilization of segment 1007 during summer. Richness and abundance in segment 1007 during winter equaled or exceeded that of segment 1006.

Control strategies for mitigation of oil-shale-related-water quality concerns  

SciTech Connect

A comprehensive study of in situ retorting at the Logan Wash has indicated the importance of developing baseline information including raw shale characterization, the elucidation of mineralogical and chemical controls on trace element mobilities from shales subjected to in situ processing, and the research necessary to identify strategies for control of recognized environmental impacts. It is impossible to assess the magnitude of trace element releases to be expected from a commercial in situ facility once banks of retorts or the entire facility is abandoned and dewatering of the area is concluded. However, laboratory-scale studies can indeed identify the relative environmental acceptability of spent shale materials generated by in situ processing. In this research, an attempt was made to relate mineralogy and leaching behavior of field-generated materials with leachate composition and solution chemical processes. The interaction of these factors will ultimately affect the impact of in situ processing on surface and groundwater quality.

Major technical goals for the Program are (1) the reduction of mortality among turbine-passed fish to 2 percent or less, compared to current levels ranging up to 30 percent or greater; and (2) development of aerating turbines that would ensure that water discharged from reservoirs has a dissolved oxygen concentration of at least 6 mg/L. These advanced, ?environmentally friendly? turbines would be suitable both for new hydropower installations and for retrofitting at existing dams. Several new turbine designs that have been developed in the initial phases of the AHTS program are described.

EPA/NMED/LANL 1998 water quality results: Statistical analysis and comparison to regulatory standards  

SciTech Connect

Four governmental agencies conducted a round of groundwater, surface water, and spring water sampling at the Los Alamos National Laboratory during 1998. Samples were split among the four parties and sent to independent analytical laboratories. Results from three of the agencies were available for this study. Comparisons of analytical results that were paired by location and date were made between the various analytical laboratories. The results for over 50 split samples analyzed for inorganic chemicals, metals, and radionuclides were compared. Statistical analyses included non-parametric (sign test and signed-ranks test) and parametric (paired t-test and linear regression) methods. The data pairs were tested for statistically significant differences, defined by an observed significance level, or p-value, less than 0.05. The main conclusion is that the laboratories' performances are similar across most of the analytes that were measured. In some 95% of the laboratory measurements there was agreement on whether contaminant levels exceeded regulatory limits. The most significant differences in performance were noted for the radioactive suite, particularly for gross alpha particle activity and Sr-90.

Use of Treated Municipal Wastewater as Power Plant Cooling System Makeup Water: Tertiary Treatment versus Expanded Chemical Regimen for Recirculating Water Quality Management  

SciTech Connect

Treated municipal wastewater is a common, widely available alternative source of cooling water for thermoelectric power plants across the U.S. However, the biodegradable organic matter, ammonia-nitrogen, carbonate and phosphates in the treated wastewater pose challenges with respect to enhanced biofouling, corrosion, and scaling, respectively. The overall objective of this study was to evaluate the benefits and life cycle costs of implementing tertiary treatment of secondary treated municipal wastewater prior to use in recirculating cooling systems. The study comprised bench- and pilot-scale experimental studies with three different tertiary treated municipal wastewaters, and life cycle costing and environmental analyses of various tertiary treatment schemes. Sustainability factors and metrics for reuse of treated wastewater in power plant cooling systems were also evaluated. The three tertiary treated wastewaters studied were: secondary treated municipal wastewater subjected to acid addition for pH control (MWW_pH); secondary treated municipal wastewater subjected to nitrification and sand filtration (MWW_NF); and secondary treated municipal wastewater subjected nitrification, sand filtration, and GAC adsorption (MWW_NFG). Tertiary treatment was determined to be essential to achieve appropriate corrosion, scaling, and biofouling control for use of secondary treated municipal wastewater in power plant cooling systems. The ability to control scaling, in particular, was found to be significantly enhanced with tertiary treated wastewater compared to secondary treated wastewater. MWW_pH treated water (adjustment to pH 7.8) was effective in reducing scale formation, but increased corrosion and the amount of biocide required to achieve appropriate biofouling control. Corrosion could be adequately controlled with tolytriazole addition (4-5 ppm TTA), however, which was the case for all of the tertiary treated waters. For MWW_NF treated water, the removal of ammonia by nitrification helped to reduce the corrosivity and biocide demand. Also, the lower pH and alkalinity resulting from nitrification reduced the scaling to an acceptable level, without the addition of anti-scalant chemicals. Additional GAC adsorption treatment, MWW_NFG, yielded no net benefit. Removal of organic matter resulted in pitting corrosion in copper and cupronickel alloys. Negligible improvement was observed in scaling control and biofouling control. For all of the tertiary treatments, biofouling control was achievable, and most effectively with pre-formed monochloramine (2-3 ppm) in comparison with NaOCl and ClO2. Life cycle cost (LCC) analyses were performed for the tertiary treatment systems studied experimentally and for several other treatment options. A public domain conceptual costing tool (LC3 model) was developed for this purpose. MWW_SF (lime softening and sand filtration) and MWW_NF were the most cost-effective treatment options among the tertiary treatment alternatives considered because of the higher effluent quality with moderate infrastructure costs and the relatively low doses of conditioning chemicals required. Life cycle inventory (LCI) analysis along with integration of external costs of emissions with direct costs was performed to evaluate relative emissions to the environment and external costs associated with construction and operation of tertiary treatment alternatives. Integrated LCI and LCC analysis indicated that three-tiered treatment alternatives such as MWW_NSF and MWW_NFG, with regular chemical addition for treatment and conditioning and/or regeneration, tend to increase the impact costs and in turn the overall costs of tertiary treatment. River water supply and MWW_F alternatives with a single step of tertiary treatment were associated with lower impact costs, but the contribution of impact costs to overall annual costs was higher than all other treatment alternatives. MWW_NF and MWW_SF alternatives exhibited moderate external impact costs with moderate infrastructure and chemical conditioner dosing, which makes them (especially

Evaluation of Phytoremediation of Coal Bed Methane Product Water and Waters of Quality Similar to that Associated with Coal Bed Methane Reserves of the Powder River Basin, Montana and Wyoming  

SciTech Connect

U.S. emphasis on domestic energy independence, along with advances in knowledge of vast biogenically sourced coalbed methane reserves at relatively shallow sub-surface depths with the Powder River Basin, has resulted in rapid expansion of the coalbed methane industry in Wyoming and Montana. Techniques have recently been developed which constitute relatively efficient drilling and methane gas recovery and extraction techniques. However, this relatively efficient recovery requires aggressive reduction of hydrostatic pressure within water-saturated coal formations where the methane is trapped. Water removed from the coal formation during pumping is typically moderately saline and sodium-bicarbonate rich, and managed as an industrial waste product. Current approaches to coalbed methane product water management include: surface spreading on rangeland landscapes, managed irrigation of agricultural crop lands, direct discharge to ephermeral channels, permitted discharge of treated and untreated water to perennial streams, evaporation, subsurface injection at either shallow or deep depths. A Department of Energy-National Energy Technology Laboratory funded research award involved the investigation and assessment of: (1) phytoremediation as a water management technique for waste water produced in association with coalbed methane gas extraction; (2) feasibility of commercial-scale, low-impact industrial water treatment technologies for the reduction of salinity and sodicity in coalbed methane gas extraction by-product water; and (3) interactions of coalbed methane extraction by-product water with landscapes, vegetation, and water resources of the Powder River Basin. Prospective, greenhouse studies of salt tolerance and water use potential of indigenous, riparian vegetation species in saline-sodic environments confirmed the hypothesis that species such as Prairie cordgrass, Baltic rush, American bulrush, and Nuttall's alkaligrass will thrive in saline-sodic environments when water supplies sourced from coalbed methane extraction are plentiful. Constructed wetlands, planted to native, salt tolerant species demonstrated potential to utilize substantial volumes of coalbed methane product water, although plant community transitions to mono-culture and limited diversity communities is a likely consequence over time. Additionally, selected, cultured forage quality barley varieties and native plant species such as Quail bush, 4-wing saltbush, and seaside barley are capable of sustainable, high quality livestock forage production, when irrigated with coalbed methane product water sourced from the Powder River Basin. A consequence of long-term plant water use which was enumerated is elevated salinity and sodicity concentrations within soil and shallow alluvial groundwater into which coalbed methane product water might drain. The most significant conclusion of these investigations was the understanding that phytoremediation is not a viable, effective technique for management of coalbed methane product water under the present circumstances of produced water within the Powder River Basin. Phytoremediation is likely an effective approach to sodium and salt removal from salt-impaired sites after product water discharges are discontinued and site reclamation is desired. Coalbed methane product water of the Powder River Basin is most frequently impaired with respect to beneficial use quality by elevated sodicity, a water quality constituent which can cause swelling, slaking, and dispersion of smectite-dominated clay soils, such as commonly occurring within the Powder River Basin. To address this issue, a commercial-scale fluid-bed, cationic resin exchange treatment process and prototype operating treatment plant was developed and beta-tested by Drake Water Technologies under subcontract to this award. Drake Water Technologies secured U.S. Patent No. 7,368,059-B2, 'Method for removal of benevolent cations from contaminated water', a beta Drake Process Unit (DPU) was developed and deployed for operation in the Powder River Basin.

Computeer-based decision support tools for evaluation of actions affecting flow and water quality in the San Joaquin Basin  

SciTech Connect

This document is a preliminary effort to draw together some of the important simulation models that are available to Reclamation or that have been developed by Reclamation since 1987. This document has also attempted to lay out a framework by which these models might be used both for the purposes for which they were originally intended and to support the analysis of other issues that relate to the hydrology and to salt and water quality management within the San Joaquin Valley. To be successful as components of a larger Decision Support System the models should to be linked together using custom designed interfaces that permit data sharing between models and that are easy to use. Several initiatives are currently underway within Reclamation to develop GIS - based and graphics - based decision support systems to improve the general level of understanding of the models currently in use, to standardize the methodology used in making planning and operations studies and to permit improved data analysis, interpretation and display. The decision support systems should allow greater participation in the planning process, allow the analysis of innovative actions that are currently difficult to study with present models and should lead to better integrated and more comprehensive plans and policy decisions in future years.

Amending constructed roadside and urban soils with large volume-based compost applications: effects on water quality  

E-Print Network (OSTI)

Mineral nutrients imported in composted dairy manure (CDM) and municipal biosolid (CMB) amendments for highway-rights-of-way and urban landscapes can pose a threat to surface water quality. Treatments were developed to evaluate recommendations for amending roadside and urban soils with compost at large volumebased rates. Texas Department of Transportation (TxDOT) recommendations were evaluated in 2002 and 2003. Municipal recommendations were evaluated in 2004. Treatments were imposed on 4 by 1.5-m field plots on a constructed soil with an 8.5% slope. Three TxDOT compost application methods were tested; incorporation at 25% by volume (CMT), topdressing over vegetation (GUC), and topdressing a 5-cm compost woodchip mix over bare soil (ECC). In 2003, a 12.5% CMT treatment was substituted for the GUC, and two contrasting composts were compared. In 2002, soil test phosphorus (STP) concentrations (mg kg-1) were 291, 360, 410, and 1921 mg kg-1 in the 0 to 5-cm layer of a course textured CMT, fine textured CMT, GUC, and ECC treatments, respectively using CDM. In 2003, STP concentrations were 264, 439, 496,623, 1115, and 2203 mg kg-1, in the 0 to 5-cm layer after incorporation of CDM and CMB at the 12.5 and 25% volume-based rates, and topdressing the 5-cm CDM- or CMB-woodchip mix over bare soil, respectively. In 2004, contrasting CMB products, relatively low or high in total phosphorus (TP) were incorporated into the soil at 12.5 and 25% by volume, or imported in transplanted sod at the 25% by volume rate. The STP concentrations were 87, 147, 180, 301, 322, and 544 mg kg-1, respective to the previously defined treatments. Runoff water from 14, 10, and 8 natural rain events was used to characterize nutrient and sediment transport in 2002, 2003, and 2004, respectively. Concentration of TDP in runoff water was highly variable for roadside treatments across rain events. Mass losses of TDP were similar after CDM or CMB were incorporated into the soil at 12.5 and 25% by volume. Compost incorporation was the most effective method for limiting TP loss in runoff. Roadway and urban soils are expected to contribute greater TP losses as P concentration increases in soils.

Western oil-shale development: a technology assessment. Volume 6: oil-shale development in the Piceance Creek Basin and potential water-quality changes  

SciTech Connect

This report brackets the stream quality changes due to pre-mining pumping activites required to prepare oil shale lease Tracts C-a and C-b for modified in situ retorting. The fluxes in groundwater discharged to the surface were identified for Tract C-b in a modeling effort by another laboratory. Assumed fluxes were used for Tract C-a. The quality of the groundwater aquifers of the Piceance Basin is assumed to be that reported in the literature. The changes are bracketed in this study by assuming all premining pumping is discharged to the surface stream. In one case, the pumped water is assumed to be of a quality like that of the upper aquifer with a relatively high quality. In the second case, the pumped water is assumed to come from the lower aquifer. Complete mixing and conservation of pollutants was assumed at sample points at the White River and at Lees Ferry of the Colorado River. A discussion of possible secondary effects of oil shale and coal mining is presented. In addition, a discussion of the uncertainties associated with the assumptions used in this study and alternative uses for the water to prevent stream contamination by oil shale development is provided.

The goal was to correlate trends in the moments with wind velocity and direction. Although the center of mass appears to increase when the wind is blowing into the radar antenna, no other conclusions have been drawn from the higher order moments.

Numerically Simulating the Hydrodynamic and Water Quality Environment for Migrating Salmon in the Lower Snake River, 2002-2003 Technical Report.  

DOE Green Energy (OSTI)

Summer temperatures in the Lower Snake River can be altered by releasing cold waters that originate from deep depths within Dworshak Reservoir. These cold releases are used to lower temperatures in the Clearwater and Lower Snake Rivers and to improve hydrodynamic and water quality conditions for migrating aquatic species. This project monitored the complex three-dimensional hydrodynamic and thermal conditions at the Clearwater and Snake River confluence and the processes that led to stratification of Lower Granite Reservoir (LGR) during the late spring, summer, and fall of 2002. Hydrodynamic, water quality, and meteorological conditions around the reservoir were monitored at frequent intervals, and this effort is continuing in 2003. Monitoring of the reservoir is a multi-year endeavor, and this report spans only the first year of data collection. In addition to monitoring the LGR environment, a three-dimensional hydrodynamic and water quality model has been applied. This model uses field data as boundary conditions and has been applied to the entire 2002 field season. Numerous data collection sites were within the model domain and serve as both calibration and validation locations for the numerical model. Errors between observed and simulated data varied in magnitude from location to location and from one time to another. Generally, errors were small and within expected ranges, although, as additional 2003 field data becomes available, model parameters may be improved to minimize differences between observed and simulated values. A two-dimensional, laterally-averaged hydrodynamic and water quality model was applied to the three reservoirs downstream of LGR (the pools behind Little Goose, Lower Monumental, and Ice Harbor Dams). A two-dimensional model is appropriate for these reservoirs because observed lateral thermal variations during summer and fall 2002 were almost negligible; however, vertical thermal variations were quite large (see USACE 2003). The numerical model was applied to each reservoir independently to simulate the time period between May 1 and October 1, 2002. Differences between observed and simulated data were small, although improvements to model coefficients may be performed as additional thermal data, collected in the reservoirs during 2003, becomes available.

The Development and Optimization of Techniques for Monitoring Water Quality on-Board Spacecraft Using Colorimetric Solid-Phase Extraction (C-SPE)  

Science Conference Proceedings (OSTI)

The main focus of this dissertation is the design, development, and ground and microgravity validation of methods for monitoring drinking water quality on-board NASA spacecraft using clorimetric-solid phase extraction (C-SPE). The Introduction will overview the need for in-flight water quality analysis and will detail some of the challenges associated with operations in the absence of gravity. The ability of C-SPE methods to meet these challenges will then be discussed, followed by a literature review on existing applications of C-SPE and similar techniques. Finally, a brief discussion of diffuse reflectance spectroscopy theory, which provides a means for analyte identification and quantification in C-SPE analyses, is presented. Following the Introduction, four research chapters are presented as separate manuscripts. Chapter 1 reports the results from microgravity testing of existing C-SPE methods and procedures aboard NASA's C-9 microgravity simulator. Chapter 2 discusses the development of a C-SPE method for determining the total concentration of biocidal silver (i.e., in both dissolved and colloidal forms) in water samples. Chapter 3 presents the first application of the C-SPE technique to the determination of an organic analyte (i.e., formaldehyde). Chapter 4, which is a departure from the main focus of the thesis, details the results of an investigation into the effect of substrate rotation on the kinetics involved in the antigen and labeling steps in sandwich immunoassays. These research chapters are followed by general conclusions and a prospectus section.

Steam Quality  

E-Print Network (OSTI)

"STEAM QUALITY has been generally defined as the amount of moisture/vapor (or lack thereof) contained within steam produced from some form of boiler. It has long been used as the standard term for the measurement of ""wet or dry"" steam and as a means of measuring enthalpy. Totally dry steam is said to be ""saturated"" steam. It is sometimes defined as the ""dryness faction"". The term in its historical denotation refers to a physical attribute of the steam. That attribute being ""what is the percentage water vapor content of the steam"" as compared to the amount of steam. Dry saturated steam is steam which carries no water vapor with it and is defined as having a quality of 1.00 (100%). Since water vapor is always present at the interface between the water level and the steam in a boiler, some water vapor will always tend to pass through the system with the steam. Hence, a continuing problem. If steam does carry water vapor past the separators it will tend to coalesce as a liquid, and in doing so it also will carry boiler chemicals with it."

Twenty-Plus Years of Environmental Change and Ecological Recovery of East Fork Poplar Creek: Background and Trends in Water Quality  

SciTech Connect

In May 1985, a National Pollutant Discharge Elimination System permit was issued for the Department of Energy's Y-12 National Security Complex (Y-12 Complex) in Oak Ridge, Tennessee, USA, allowing discharge of effluents to East Fork Poplar Creek (EFPC). The effluents ranged from large volumes of chlorinated once-through cooling water and cooling tower blow-down to smaller discharges of treated and untreated process wastewaters, which contained a mixture of heavy metals, organics, and nutrients, especially nitrates. As a condition of the permit, a Biological Monitoring and Abatement Program (BMAP) was developed to meet two major objectives: demonstrate that the established effluent limitations were protecting the classified uses of EFPC, and document the ecological effects resulting from implementing a Water Pollution Control Program at the Y-12 Complex. The second objective is the primary focus of the other papers in this special series. This paper provides a history of pollution and the remedial actions that were implemented; describes the geographic setting of the study area; and characterizes the physicochemical attributes of the sampling sites, including changes in stream flow and temperature that occurred during implementation of the BMAP. Most of the actions taken under the Water Pollution Control Program were completed between 1986 and 1998, with as many as four years elapsing between some of the most significant actions. The Water Pollution Control Program included constructing nine new wastewater treatment facilities and implementation of several other pollution-reducing measures, such as a best management practices plan; area-source pollution control management; and various spill-prevention projects. Many of the major actions had readily discernable effects on the chemical and physical conditions of EFPC. As controls on effluents entering the stream were implemented, pollutant concentrations generally declined and, at least initially, the volume of water discharged from the Y-12 Complex declined. This reduction in discharge was of ecological concern and led to implementation of a flow management program for EFPC. Implementing flow management, in turn, led to substantial changes in chemical and physical conditions of the stream: stream discharge nearly doubled and stream temperatures decreased, becoming more similar to those in reference streams. While water quality clearly improved, meeting water quality standards alone does not guarantee protection of a waterbody's biological integrity. Results from studies on the ecological changes stemming from pollution-reduction actions, such as those presented in this series, also are needed to understand how best to restore or protect biological integrity and enhance ecological recovery in stream ecosystems. With a better knowledge of the ecological consequences of their decisions, environmental managers can better evaluate alternative actions and more accurately predict their effects.

Environmental Management (2008) 41:367–377 DOI 10.1007/s00267-007-9033-y Headwater Influences on Downstream Water Quality  

E-Print Network (OSTI)

Abstract We investigated the influence of riparian and whole watershed land use as a function of stream size on surface water chemistry and assessed regional variation in these relationships. Sixty-eight watersheds in four level III U.S. EPA ecoregions in eastern Kansas were selected as study sites. Riparian land cover and watershed land use were quantified for the entire watershed, and by Strahler order. Multiple regression analyses using riparian land cover classifications as independent variables explained among-site variation in water chemistry parameters, particularly total nitrogen (41%), nitrate (61%), and total phosphorus (63%) concentrations. Whole watershed land use explained slightly less variance, but riparian and whole watershed land use were so tightly correlated that it was difficult to separate their effects. Water chemistry parameters sampled in downstream reaches were most closely correlated with riparian land cover adjacent to the smallest (first-order) streams of watersheds or land use in the entire watershed, with riparian zones immediately upstream of sampling sites offering less explanatory power as stream size increased. Interestingly, headwater effects were evident even at times when these small streams were unlikely to be flowing. Relationships were similar among ecoregions, indicating that land use characteristics were most responsible for water quality variation among watersheds. These findings suggest that nonpoint pollution control

Photoelectron Spectroscopy under Ambient Pressure and Temperature Conditions  

SciTech Connect

We describe the development and applications of novel instrumentation for photoemission spectroscopy of solid or liquid surfaces in the presence of gases under ambient conditions or pressure and temperature. The new instrument overcomes the strong scattering of electrons in gases by the use of an aperture close to the surface followed by a differentially-pumped electrostatic lens system. In addition to the scattering problem, experiments in the presence of condensed water or other liquids require the development of special sample holders to provide localized cooling. We discuss the first two generations of Ambient Pressure PhotoEmission Spectroscopy (APPES) instruments developed at synchrotron light sources (ALS in Berkeley and BESSY in Berlin), with special focus on the Berkeley instruments. Applications to environmental science and catalytic chemical research are illustrated in two examples.

Research Project on CO2 Geological Storage and Groundwater Resources: Water Quality Effects Caused by CO2 Intrusion into Shallow Groundwater  

SciTech Connect

One promising approach to reduce greenhouse gas emissions is injecting CO{sub 2} into suitable geologic formations, typically depleted oil/gas reservoirs or saline formations at depth larger than 800 m. Proper site selection and management of CO{sub 2} storage projects will ensure that the risks to human health and the environment are low. However, a risk remains that CO{sub 2} could migrate from a deep storage formation, e.g. via local high-permeability pathways such as permeable faults or degraded wells, and arrive in shallow groundwater resources. The ingress of CO{sub 2} is by itself not typically a concern to the water quality of an underground source of drinking water (USDW), but it will change the geochemical conditions in the aquifer and will cause secondary effects mainly induced by changes in pH, in particular the mobilization of hazardous inorganic constituents present in the aquifer minerals. Identification and assessment of these potential effects is necessary to analyze risks associated with geologic sequestration of CO{sub 2}. This report describes a systematic evaluation of the possible water quality changes in response to CO{sub 2} intrusion into aquifers currently used as sources of potable water in the United States. Our goal was to develop a general understanding of the potential vulnerability of United States potable groundwater resources in the event of CO{sub 2} leakage. This goal was achieved in two main tasks, the first to develop a comprehensive geochemical model representing typical conditions in many freshwater aquifers (Section 3), the second to conduct a systematic reactive-transport modeling study to quantify the effect of CO{sub 2} intrusion into shallow aquifers (Section 4). Via reactive-transport modeling, the amount of hazardous constituents potentially mobilized by the ingress of CO{sub 2} was determined, the fate and migration of these constituents in the groundwater was predicted, and the likelihood that drinking water standards might be exceeded was evaluated. A variety of scenarios and aquifer conditions was considered in a sensitivity evaluation. The scenarios and conditions simulated in Section 4, in particular those describing the geochemistry and mineralogy of potable aquifers, were selected based on the comprehensive geochemical model developed in Section 3.

Guidance to the Electric Power Industry for Implementing Environmental Protection Agency's 2001 Methylmercury Water Quality Criterio n  

Science Conference Proceedings (OSTI)

Adoption of the U. S. Environmental Protection Agency's (EPA's) methylmercury fish tissue criterion in 2001 raised many issues for permitting agencies and for individual discharges. Among them is how to translate from a tissue-based criterion to a water-column criteria for methylmercury. Adoption of a methylmercury standard requires translation to other forms of mercury if, for instance, permits continue to be written in terms of total recoverable mercury. This report covers a number of topics raised by ...

Effects of in-situ oil-shale retorting on water quality near Rock Springs, Wyoming, Volume 1  

SciTech Connect

Experimental in-situ retorting techniques (methods of extracting shale oil without mining) were used from 1969 to 1979 by the Department of Energy's (DOE) Laramie Energy Technology Center (LETC) at a test area near Rock Springs in southwestern Wyoming. The retorting experiments at site 9 have produced elevated concentrations of some contaminants in the ground water. During 1988 and 1989, the US Geological Survey, in cooperation with the US Department of Energy, conducted a site characterization study to evaluate the chemical contamination of ground water at the site. Water samples from 34 wells were analyzed; more than 70 identifiable organic compounds were detected using a combination of gas chromatography and mass spectrometry analytical methods. This report provides information that can be used to evaluate possible remedial action for the site. Remediation techniques that may be applicable include those techniques based on removing the contaminants from the aquifer and those based on immobilizing the contaminants. Before a technique is selected, the risks associated with the remedial action (including the no-action alternative) need to be assessed, and the criteria to be used for decisions regarding aquifer restoration need to be defined. 31 refs., 23 figs., 9 tabs.

Determination of the toxicity, water-quality interactions, and biomagnification of selenium in aquatic food chains. Technical report for 15 August 1987-14 August 1989 (Final)  

Science Conference Proceedings (OSTI)

Ecological degradation of aquatic ecosystems associated with the presence of elevated concentrations of the trace element selenium has been of considerable scientific, governmental, and public concern. The increased flux of selenium into several aquatic ecosystems, due to anthropogenic activities, has resulted in death, teratogenesis, reproductive impairment and decreased populations in fish and waterfowl communities in the systems. Research is continuing on several investigations into the toxicity, bioaccumulation, transfer, and biotransformation of selenium in aquatic organisms and laboratory food chains. Initial studies were primarily concerned with the comparative acute and chronic toxicity, water-quality interactions, and toxicological interactions of several chemical species of selenium to a variety of aquatic organisms. Further research was directed towards the biotransformation, transfer, and subsequent bioaccumulation of selenium in simplified laboratory aquatic food chains. Studies on the transfer, bioaccumulation, and toxicity of selenium from dietary sources to consumers were conducted. The development of methodology for determining and quantifying the biochemical speciation of selenium in aquatic organisms was initiated.

Optimization of non-aqueous electrolytes for Primary lithium/air batteries operated in Ambient Enviroment  

Science Conference Proceedings (OSTI)

The selection and optimization of non-aqueous electrolytes for ambient operations of lithium/air batteries has been studied. Organic solvents with low volatility and low moisture absorption are necessary to minimize the change of electrolyte compositions and the reaction between lithium anode and water during discharge process. It is critical to make the electrolytes with high polarity so that it can reduce wetting and flooding of carbon based air electrode and lead to improved battery performance. For ambient operations, the viscosity, ionic conductivity, and oxygen solubility of the electrolyte are less important than the polarity of organic solvents once the electrolyte has reasonable viscosity, conductivity, and oxygen solubility. It has been found that PC/EC mixture is the best solvent system and LiTFSI is the most feasible salt for ambient operations of Li/air batteries. Battery performance is not very sensitive to PC/EC ratio or salt concentration.

Ambient Operation of Li/Air Batteries  

Science Conference Proceedings (OSTI)

In this work, Li/air batteries based on nonaqueous electrolytes were investigated in ambient conditions (with an oxygen partial pressure of 0.21 atm and relative humidity of ~20%). A heat-sealable polymer membrane was used as both an oxygen-diffusion membrane and as a moisture barrier for Li/air batteries. The membrane also can minimize the evaporation of the electrolyte from the batteries. Li/air batteries with this membrane can operate in ambient conditions for more than one month with a specific energy of 362 Wh kg-1, based on the total weight of the battery including its packaging. Among various carbon sources used in this work, Li/air batteries using Ketjenblack (KB) carbon-based air electrodes exhibited the highest specific energy. However, KB-based air electrodes expanded significantly and absorbed much more electrolyte than electrodes made from other carbon sources. The weight distribution of a typical Li/air battery using the KB-based air electrode was dominated by the electrolyte (~70%). Lithium-metal anodes and KB-carbon anodes account for only 5.12% and 5.78% of the battery weight, respectively. We also found that only ~ 20% of the mesopore volume of the air electrode was occupied by reaction products after discharge. To further improve the specific energy of the Li/air batteries, the microstructure of the carbon electrode needs to be further improved to absorb much less electrolyte while still holding significant amounts of reaction products

Spectral analysis of ambient weather patterns  

DOE Green Energy (OSTI)

A Fourier spectral analysis of ambient weather data, consisting of global and direct solar radiation, dry and wet bulb temperatures, and wind speed, is given. By analyzing the heating and cooling seasons independently, seasonal variations are isolated and a cleaner spectrum emerges. This represents an improvement over previous work in this area, in which data for the entire year were analyzed together. As a demonstration of the efficacy of this method, synthetic data constructed with a small number of parameters are used in typical simulations, and the results are compared with those obtained with the original data. A spectral characterization of fluctuations around the moving average is given, and the changes in the fluctuation from season to season are examined.

Ambient-pressure silica aerogel films  

SciTech Connect

Very highly porous (aerogel) silica films with refractive index in the range 1.006--1.05 (equivalent porosity 98.5--88%) were prepared by an ambient-pressure process. It was shown earlier using in situ ellipsometric imaging that the high porosity of these films was mainly attributable to the dilation or `springback` of the film during the final stage of drying. This finding was irrefutably reconfirmed by visually observing a `springback` of >500% using environmental scanning electron microscopy (ESEM). Ellipsometry and ESEM also established the near cent per cent reversibility of aerogel film deformation during solvent intake and drying. Film thickness profile measurements (near the drying line) for the aerogel, xerogel and pure solvent cases are presented from imaging ellipsometry. The thickness of these films (crack-free) were controlled in the range 0.1-3.5 {mu}m independent of refractive index.

Montesinos, Andrey Shavorskiy, Valerie Keller, Nicolas Keller, Marta I. Litter, Hendrik Bluhm, Miquel Salmeron, and Hugo Destaillats Journal J. Phys. Chem. Lett. Volume 4 Start Page 536 Issue 3 Pagination 536-541 Date Published 01/2013 Abstract Self-cleaning surfaces containing TiO2 nanoparticles have been postulated to efficiently remove NOx from the atmosphere. However, UV irradiation of NOx adsorbed on TiO2 also was shown to form harmful gas-phase byproducts such as HONO and N2O that may limit their depolluting potential. Ambient pressure XPS was used to study surface and gas-phase species formed during adsorption of NO2 on TiO2 and subsequent UV irradiation at λ = 365 nm. It is shown here that NO3-, adsorbed on TiO2 as a byproduct of NO2 disproportionation, was quantitatively converted to surface NO2 and other reduced nitrogenated species under UV irradiation in the absence of moisture. When water vapor was present, a faster NO3- conversion occurred, leading to a net loss of surface-bound nitrogenated species. Strongly adsorbed NO3- in the vicinity of coadsorbed K+ cations was stable under UV light, leading to an efficient capture of nitrogenated compounds.

Characterization of Ambient PM2.5 in the Upper Midwest Characterization of Ambient PM2.5 in the Upper Midwest As part of a Cooperative Agreement with DOE-NETL, the University of North Dakota Energy and Environmental Research Center (EERC) is developing advanced sampling and analysis methodologies for particulate matter that can be used for source apportionment and to assist in health studies. These techniques will be used to determine sources of fine particulate matter in rural states such as North Dakota. Ambient particulate matter (PM) sampling and automated scanning electron microscopy, (ASEM) are being used to characterize and evaluate the sources of PM2.5 at three rural sites. Land use in the sampling site locations is dominated by ranching and small grain farming. Potential sources of PM in these areas include diesel- and gasoline-fueled motor vehicles, fugitive dust from gravel roads and agriculture, vegetation and fires, an oil refinery, and coal-fired power plants. PM2.5 samples were collected using an automatic cartridge collection unit for ASEM analysis. An ASEM method has been developed to size and chemically classify individual particles composing PM2.5.

Depth and temporal variations in water quality of the Snake River Plain aquifer in well USGS-59 near the Idaho Chemical Processing Plant at the Idaho National Engineering and Environmental Laboratory  

SciTech Connect

In-situ measurements of the specific conductance and temperature of ground water in the Snake River Plain aquifer were collected in observation well USGS-59 near the Idaho Chemical Processing Plant at the Idaho National Engineering and Environmental Laboratory. These parameters were monitored at various depths in the aquifer from October 1994 to August 1995. The specific conductance of ground water in well USGS-59, as measured in the borehole, ranged from about 450 to 900 {micro}S/cm at standard temperature (25 C). The pumping cycle of the production wells at the Idaho Chemical Processing Plant causes changes in borehole circulation patterns, and as a result the specific conductance of ground water at some depths in the well varies by up to 50% over a period of about 14 hours. However, these variations were not observed at all depths, or during each pumping cycle. The temperature of ground water in the well was typically between 12.8 and 13.8 C. The results of this study indicate that temporal variations in specific conductance of the ground water at this location are caused by an external stress on the aquifer--pumping of a production well approximately 4,000 feet away. These variations are believed to result from vertical stratification of water quality in the aquifer and a subsequent change in intrawell flow related to pumping. When sampling techniques that do not induce a stress on the aquifer (i.e., thief sampling) are used, knowledge of external stresses on the system at the time of sampling may aid in the interpretation of geochemical data.

Impact Of Standing Water On Saltstone Placement II - Hydraulic Conductivity Data  

Science Conference Proceedings (OSTI)

The amount of water present during placement and subsequent curing of saltstone has the potential to impact several properties important for grout quality. An active drain water system can remove residual standing water and expose the surface of the placed saltstone to air. Oxidation of the saltstone may result in an increase in the leachability of redox sensitive elements. A dry surface can lead to cracking, causing an increase in hydraulic conductivity. An inactive drain water system can allow standing water that generates unnecessary hydrostatic head on the vault walls. Standing water that cannot be removed via the drain system will be available for potential incorporation into subsequent grout placements. The objective of this work is to study the impact of standing water on grout quality pertaining to disposal units. A series of saltstone mixes was prepared and cured at ambient temperature to evaluate the impact of standing water on saltstone placement. The samples were managed to control drying effects on leachability by either exposing or capping the samples. The water to premix ratio was varied to represent a range of processing conditions. Samples were analyzed for density, leachability, and hydraulic conductivity. Report SRNL-STI-2012-00546 was issued detailing the experimental procedure, results, and conclusions related to density and leachability. In the previous report, it was concluded that: density tends to increase toward the bottom of the samples. This effect is pronounced with excess bleed water; drying of the saltstone during curing leads to decreased Leachability Index (more leaching) for potassium, sodium, rhenium, nitrite, and nitrate; there is no noticeable effect on saltstone oxidation/leachability by changing the water to premix ratio (over the range studied), or by pouring into standing water (when tested up to 10 volume percent). The hydraulic conductivity data presented in this report show that samples cured exposed to the atmosphere had about three orders of magnitude higher hydraulic conductivity than any of the other samples. Considering these data, along with the results presented in the previous report, leads to the conclusion that small changes in water to premix ratio and the inclusion of up to 10 volume percent standing water should not be expected to have a detrimental effect on saltstone grout quality. The hydraulic conductivity results further demonstrate that curing in a moist environment is critical to maintaining saltstone quality.

Final Report: Development of a Thermal and Water Management System for PEM Fuel Cell  

DOE Green Energy (OSTI)

This final program report is prepared to provide the status of program activities performed over the period of 9 years to develop a thermal and water management (TWM) system for an 80-kW PEM fuel cell power system. The technical information and data collected during this period are presented in chronological order by each calendar year. Balance of plant (BOP) components of a PEM fuel cell automotive system represents a significant portion of total cost based on the 2008 study by TIAX LLC, Cambridge, MA. The objectives of this TWM program were two-fold. The first objective was to develop an advanced cooling system (efficient radiator) to meet the fuel cell cooling requirements. The heat generated by the fuel cell stack is a low-quality heat (small difference between fuel cell stack operating temperature and ambient air temperature) that needs to be dissipated to the ambient air. To minimize size, weight, and cost of the radiator, advanced fin configurations were evaluated. The second objective was to evaluate air humidification systems which can meet the fuel cell stack inlet air humidity requirements. The moisture from the fuel cell outlet air is transferred to inlet air, thus eliminating the need for an outside water source. Two types of humidification devices were down-selected: one based on membrane and the other based on rotating enthalpy wheel. The sub-scale units for both of these devices have been successfully tested by the suppliers. This project addresses System Thermal and Water Management.

Impact Of Standing Bleed Water On Saltstone Placement  

Science Conference Proceedings (OSTI)

Oxidation of the saltstone may result in an increase in the leachability of redox sensitive elements. A dry surface can lead to cracking, causing an increase in hydraulic conductivity. An inactive drain water system can allow standing water that generates unnecessary hydrostatic head on the vault walls. Standing water that cannot be removed via the drain system will be available for potential incorporation into subsequent grout placements. The objective of this work is to study the impact of standing water on grout quality pertaining to disposal units. A series of saltstone mixes were prepared, and cured at ambient temperature to evaluate the impact of standing water on saltstone placement. The samples were managed to control drying effects on leachability by either exposing or capping the samples. The water to premix ratio was varied to represent a range of processing conditions. Samples were analyzed for density, leachability, and hydraulic conductivity. A monolith of each composition was cut into four sections to analyze the homogeneity of the sample with respect to vertical position within the sample. The density of each section was measured by two methods, helium pycnometry and by ASTM 642-06. The results show a trend of increasing density with increasing depth in the samples. This effect is more pronounced with the inclusion of excess bleed water and indicative of increased settling. The leachability of the eight different samples was analyzed by ANS/ANSI 16.1 method. These results indicate that drying of the saltstone during curing leads to decreased Leachability Indices (indicative of more release) for potassium, sodium, rhenium, nitrite, and nitrate. This may be caused by shrinkage cracking in the samples creating additional pathways for contaminant release. There was no noticeable effect on leachability by changing the water to premix ratio or by including excess bleed water. There was no detectable chromium release in any of the samples. Chromium and rhenium were added in equal amounts to determine whether rhenium might be an acceptable surrogate for chromium, a hazardous material. This testing shows no correlation between the behavior of the two elements, as chromium is not released at detectable levels and rhenium is released at a comparable rate to nitrate, the most prevalent and mobile species in saltstone.

In an effort to conserve water, drought-proof operating plants and control costs, the critical relationship of water and energy is clearly exposed. Five years of effort has transpired into countless studies, more than 100 projects and a clear understanding that the highest value opportunities for water conservation usually exist where there is the strongest interaction of water and energy. Steam management systems, process cooling, high quality water production and waste water treatment represent high probability areas for water conservation and value capture. These are not the only areas to reduce water management infrastructure and environmental footprint but they represent areas with the high potential for efforts to return bottom line value.

Cardiopulmonary Toxicity Induced by Ambient Particulate Matter (BI City Concentrated Ambient Particle Study)  

SciTech Connect

Alterations in heart rate variability (HRV) have been reported in rodents exposed to concentrated ambient particles (CAPs) from different regions of the United States. The goal of this study was to compare alterations in cardiac function induced by CAPs in two distinct regional atmospheres. AirCARE 1, a mobile laboratory with an EPA/Harvard fine particle (particulate matter <2.5 {micro}m; PM{sub 2.5}) concentrator was located in urban Detroit, MI, where the PM mixture is heavily influenced by motor vehicles, and in Steubenville, OH, where PM is derived primarily from long-range transport and transformation of power plant emissions, as well as from local industrial operations. Each city was studied during both winter and summer months, for a total of four sampling periods. Spontaneously hypertensive rats instrumented for electrocardiogram (ECG) telemetry were exposed to CAPs 8 h/day for 13 consecutive days during each sampling period. Heart rate (HR), and indices of HRV (standard deviation of the average normal-to-normal intervals [SDNN]; square root of the mean squared difference of successive normal-to-normal intervals [rMSSD]), were calculated for 30-minute intervals during exposures. A large suite of PM components, including nitrate, sulfate, elemental and organic carbon, and trace elements, were monitored in CAPs and ambient air. In addition, a unique sampler, the Semi-Continuous Elements in Air Sampler (SEAS) was employed to obtain every-30-minute measurements of trace elements. Positive matrix factorization (PMF) methods were applied to estimate source contributions to PM{sub 2.5}. Mixed modeling techniques were employed to determine associations between pollutants/CAPs components and HR and HRV metrics. Mean CAPs concentrations in Detroit were 518 and 357 {micro}g/m{sup 3} (summer and winter, respectively) and 487 and 252 {micro}g/m{sup 3} in Steubenville. In Detroit, significant reductions in SDNN were observed in the summer in association with cement/lime, iron/steel, and gasoline/diesel factors, while associations with the sludge incineration factor and components were less consistent. In winter, increases in HR were associated with a refinery factor and its components. CAPs-associated HR decreases in winter were linked to sludge incineration, cement/lime, and coal/secondary factors and the majority of their associated components. Specific relationships for increased rMSSD in winter were difficult to determine due to lack of consistency between factors and associated constituents. In Steubenville, we observed significant changes in HR (both increases and decreases), SDNN, and rMSSD in the summer, but not in the winter. We examined associations between individual source factors/PM components and HRV metrics segregated by predominant wind direction (NE or SW). Changes in HR (both increases and decreases) were linked with metal processing, waste incineration, and iron/steel factors along with most of their associated elemental constituents. Reductions in SDNN were associated with metal processing, waste incineration, and mobile source factors and the majority of elements loading onto these factors. There were no consistent associations between changes in rMSSD and source factors/components. Despite the large number of coal-fired power plants in the region, and therefore the large contribution of secondary sulfate to overall PM mass, we did not observe any associations with the coal/secondary factor or with the majority of its associated components. There were several inconsistencies in our results which make definitive conclusions difficult. For example, we observed opposing signs of effect estimates with some components depending on season, and with others depending on wind direction. In addition, our extensive dataset clearly would be subject to issues of multiple comparisons, and the 'true' significant results are unknown. Overall, however, our results suggest that acute changes in cardiac function were most strongly associated with local industrial sources. Results for coal-fired power plant-deriv

Identification of dynamic properties from ambient vibration measurements  

SciTech Connect

To better understand the dynamic behavior of structures under normal dynamic loads as well as extreme loads such as those caused by seismic events or high winds, it is desirable to measure the dynamic properties (resonant frequencies, mode shapes and modal damping) of these structures. The cross-correlation function between two response measurements made on an ambiently excited structure is shown to have the same form as the system`s impulse response function. Therefore, standard time-domain curve-fitting procedures such as the complex exponential method, which are typically applied to impulse response functions, can now be applied to the cross-correlation functions to estimate the resonant frequencies and modal damping of the structure. A direct comparison of resonant frequencies identified by curve-fitting the cross-correlation functions, using traffic excitation as the ambient vibration source, and modal properties identified by standard forced vibration testing of a highway bridge, after traffic was removed, showed a maximum discrepancy of 3.63%. Similar comparisons for the average modal damping values identified by the two methods showed a 9.82% difference. This experimental verification implies that the proposed method of analyzing ambient vibration data has the potential to accurately assess the dynamic properties of large structures subjected to seismic excitations and small structures that are tested on a shake table.

A low noise, low power consumption, compact, ambient temperature signal amplifier for a Cadmium Zinc Telluride (CZT) radiation detector. The amplifier can be used within a larger system (e.g., including a multi-channel analyzer) to allow isotopic analysis of radionuclides in the field. In one embodiment, the circuit stages of the low power, low noise amplifier are constructed using integrated circuit (IC) amplifiers , rather than discrete components, and include a very low noise, high gain, high bandwidth dual part preamplification stage, an amplification stage, and an filter stage. The low noise, low power consumption, compact, ambient temperature amplifier enables the CZT detector to achieve both the efficiency required to determine the presence of radio nuclides and the resolution necessary to perform isotopic analysis to perform nuclear material identification. The present low noise, low power, compact, ambient temperature amplifier enables a CZT detector to achieve resolution of less than 3% full width at half maximum at 122 keV for a Cobalt-57 isotope source. By using IC circuits and using only a single 12 volt supply and ground, the novel amplifier provides significant power savings and is well suited for prolonged portable in-field use and does not require heavy, bulky power supply components.

Nanosecond Time Resolved and Steady State Infrared Studies of Photoinduced Decomposition of TATB at Ambient and Elevated Pressures  

SciTech Connect

The timescale and/or products of photo-induced decomposition of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) were investigated at ambient pressure and compared with products formed at elevated pressure (i.e. 8 GPa). Ultrafast time-resolved infrared and steady state Fourier transform IR (FTIR) spectroscopies were used to probe TATB and its products after photoexcitation with a 5 ns pulse of 532 nm light. At ambient pressure, transient spectra of TATB indicate that the molecule has significantly decomposed within 60 ns; transient spectra also indicate that formation of CO{sub 2}, an observed decomposition product, is complete within 30-40 s. Proof of principle time resolved experiments at elevated pressures were performed and are discussed briefly. Comparison of steady-state FTIR spectra obtained at ambient and elevated pressure (ca. 8 GPa) indicate that the decomposition products vary with pressure. We find evidence for water as a decomposition product only at elevated pressure.

Wheat grain quality under enhanced tropospheric CO{sub 2} and O{sub 3} concentrations  

SciTech Connect

It is expected that the progressive increase of tropospheric trace gases such as CO{sub 2} and O{sub 3} will have a significant impact on agricultural production. The single and combined effects of CO{sub 2} enrichment and tropospheric O{sub 3} on grain quality characteristics in soft red winter wheat (Triticum aestivum L.) were examined in field studies using 3 m in diam. open-top chambers. Wheat cultivars {open_quotes}Massey{close_quotes} (1991) and {open_quotes}Saluda{close_quotes} (1992) were exposed to two CO{sub 2} concentrations (350 vs. 500 {mu}mol CO{sub 2} mol{sup {minus}1}; 12 h d{sup {minus}1}) in combination with two O{sub 3} regimes (charcoal-filtered air vs. ambient air + 40 {plus_minus} 20 nmol O{sub 3} mol{sup {minus}1}, 7 h d{sup {minus}1}; Monday to Friday) from late March until maturity in June. Grain quality characteristics investigated included: test weight, milling and baking quality, flour yield, protein content, softness equivalent, alkaline water retention capacity, and cookie diameter. In general, exposure of plants to either elevated CO{sub 2} or weekly chronic O{sub 3} episodes caused only small changes in grain quality. Milling and baking quality score were not significantly changed in response to treatments in both years. Flour yield was increased by elevated CO{sub 2} but this increase was counteracted when elevated CO{sub 2} was combined with chronic O{sub 3} exposure. Flour protein contents were increased by enhanced O{sub 3} under elevated CO{sub 2}. Although the single effect of either CO{sub 2} enrichment or chronic O{sub 3} exposure had some impact o grain quality characteristics, it was noted that the combined effect of these gases was minor. It is likely that the concomitant increase of CO{sub 2} and O{sub 3} in the troposphere will have no significant impact on wheat grain quality. 25 refs., 1 fig., 2 tabs.

Modal parameter extraction from large operating structures using ambient excitation  

DOE Green Energy (OSTI)

A technique called the Natural Excitation Technique or has been developed to response extract response parameters from large operational structure when subjected to random and unmeasured forces such as wind, road noise, aerodynamics, or waves. Six applications of NExT to ambient excitation testing and NExT analysis are surveyed in this paper with a minimum of technical detail. In the first application, NExT was applied to a controlled-yaw Horizontal-Axis Wind Turbine (HAWT). By controlling the yaw degree of freedom an important class of rotating coordinate system effects are reduced. A new shape extraction procedure was applied to this data set with good results. The second application was to a free-yaw HAWT. The complexity of the response has prompted further analytical studies and the development of a specialized visualization package. The third application of NExT was to a parked three-bladed Vertical-Axis Wind Turbine (VAWT) in which traditional modal testing could not excite all modes of interest. The shape extraction process used cross-correlation functions directly in a time-domain shape-fitting routine. The fourth application was to ground transportation systems. Ongoing work to improve driver and passenger comfort in tractor-trailer vehicles and to refine automobile body and tire models will use NExT. NExT has been used to process ambient vibration data for Finite Element Model correlation and is being used to study Structural Health Monitoring with ambient excitation. Shape fitting was performed using amplitude and phase information taken directly from the cross-spectra. The final application is to an offshore structure. This work is on-going, however initial studies have found a high-modal density, high noise content, and sparse data set.

Ambient Air Sampling During Quantum-dot Spray Deposition  

Science Conference Proceedings (OSTI)

Ambient air sampling for nano-size particle emissions was performed during spot spray coating operations with a Sono-Tek Exactacoat Benchtop system (ECB). The ECB consisted of the application equipment contained within an exhaust enclosure. The enclosure contained numerous small access openings, including an exhaust hook-up. Door access comprised most of the width and height of the front. The door itself was of the swing-out type. Two types of nanomaterials, Cadmium selenide (Cd-Se) quantum-dots (QDs) and Gold (Au) QDs, nominally 3.3 and 5 nm in diameter respectively, were applied during the evaluation. Median spray drop size was in the 20 to 60 micrometer size range.1 Surface coating tests were of short duration, on the order of one-half second per spray and ten spray applications between door openings. The enclosure was ventilated by connection to a high efficiency particulate aerosol (HEPA) filtered house exhaust system. The exhaust rate was nominally 80 ft3 per minute producing about 5 air changes per minute. Real time air monitoring with a scanning mobility particle size analyzer (SMPS ) with a size detection limit of 7 nm indicated a significant increase in the ambient air concentration upon early door opening. A handheld condensation particle counter (CPC) with a lower size limit of 10 nm did not record changes in the ambient background. This increase in the ambient was not observed when door opening was delayed for 2 minutes (~10 air changes). The ventilated enclosure controlled emissions except for cases of rapid door opening before the overspray could be removed by the exhaust. A time delay sufficient to provide 10 enclosure air changes (a concentration reduction of more than 99.99 %) before door opening prevented the release of aerosol particles in any size.2 Scanning-transmission electron microscopy (STEM) and atomic force microscopy (AFM) demonstrated the presence of agglomerates in the surfaces of the spray applied deposition. A filtered air sample of the enclosure overspray examined by AFM also demonstrated the presence of agglomerates for the Au QDs. The AFM system was not able to resolve individual QDs as was the STEM. Chemical fingerprinting of the QDs with STEM/EDS (energy dispersive spectroscopy) was performed for the Cd-Se surface deposition, but not the aerosol. Both STEM and AFM background characterization by morphology and chemical fingerprinting were performed throughout the laboratory for a period of about one year. Outdoor sources were primarily biological, combustion fume, salt and other crustal particles. Indoor sources were primarily paper/clothing fibers, spray-on insulation fragments, fiber glass, and human skin cells.

Enhanced oil recovery water requirements  

SciTech Connect

Water requirements for enhanced oil recovery (EOR) are evaluated using publicly available information, data from actual field applications, and information provided by knowledgeable EOR technologists in 14 major oil companies. Water quantity and quality requirements are estimated for individual EOR processes (steam drive; in situ combustion; and CO/sub 2/, micellar-polymer, polymer, and caustic flooding) in those states and specific geographic locations where these processes will play major roles in future petroleum production by the year 2000. The estimated quantity requirements represent the total water needed from all sources. A reduction in these quantities can be achieved by reinjecting all of the produced water potentially available for recycle in the oil recovery method. For injection water quality requirements, it is noted that not all of the water used for EOR needs to be fresh. The use of treated produced water can reduce significantly the quantities of fresh water that would be sought from other sources. Although no major EOR project to date has been abandoned because of water supply problems, competing regional uses for water, drought situations, and scarcity of high quality surface water and ground water could be impediments to certain projects in the near future.

Ambient air pollution exposure and the incidence of related health effects among racial/ethnic minorities  

Science Conference Proceedings (OSTI)

Differences among racial and ethnic groups in morbidity and mortality rates for diseases, including diseases with environmental causes, have been extensively documented. However, documenting the linkages between environmental contaminants, individual exposures, and disease incidence has been hindered by difficulties in measuring exposure for the population in general and for minority populations in particular. After briefly discussing research findings on associations of common air pollutants with disease incidence, the authors summarize recent studies of radial/ethnic subgroup differences in incidence of these diseases in the US. They then present evidence of both historic and current patterns of disproportionate minority group exposure to air pollution as measured by residence in areas where ambient air quality standards are violated. The current indications of disproportionate potential exposures of minority and low-income populations to air pollutants represent the continuation of a historical trend. The evidence of linkage between disproportionate exposure to air pollution of racial/ethnic minorities and low-income groups and their higher rates of some air pollution-related diseases is largely circumstantial. Differences in disease incidence and mortality rates among racial/ethnic groups are discussed for respiratory diseases, cancers, and lead poisoning. Pollutants of concern include CO, Pb, SO{sub 2}, O{sub 3}, and particulates.

Hydrogen Storage at Ambient Temperature by the Spillover Mechanism  

DOE Green Energy (OSTI)

The goal of this project was to develop new nanostructured sorbent materials, using the hydrogen spillover mechanism that could meet the DOE 2010 system targets for on-board vehicle hydrogen storage. Hydrogen spillover may be broadly defined as the transport (i.e., via surface diffusion) of dissociated hydrogen adsorbed or formed on a first surface onto another surface. The first surface is typically a metal (that dissociates H2) and the second surface is typically the support on which the metal is doped. Hydrogen spillover is a well documented phenomenon in the catalysis literature, and has been known in the catalysis community for over four decades, although it is still not well understood.1, 2 Much evidence has been shown in the literature on its roles played in catalytic reactions. Very little has been studied on hydrogen storage by spillover at ambient temperature. However, it is also known to occur at such temperature, e.g., direct evidence has been shown for spillover on commercial fuel-cell, highly dispersed Pt/C, Ru/C and PtRu/C catalysts by inelastic neutron scattering.3 To exploit spillover for storage, among the key questions are whether spillover is reversible at ambient temperature and if the adsorption (refill) and desorption rates at ambient temperature are fast enough for automotive applications. In this project, we explored new sorbents by using a transition metal (e.g., Pt, Ru, Pd and Ni) as the H2 dissociation source and sorbents as the hydrogen receptor. The receptors included superactivated carbons (AX-21 and Maxsorb), metal organic frameworks (MOFs) and zeolites. Different metal doping methods have been used successfully to achieve high metal dispersion thereby allowing significant spillover enhancements, as well as a bridging technique used for bridging to MOFs. Among the metals tested, Pt is the hardest to achieve high metal dispersion (and consequently spillover) while Ru is the easiest to disperse. By properly dispersing Pt on superactivated carbons (by following detailed doping and activation conditions given in our publications, e.g., Ref. 12), the storage capacities are increased two-fold (doubled) while slightly more than doubled by Ru doping. The bridging technique remains highly empirical and sample-to-sample consistency is difficult to achieve; however, significant enhancements by spillover can be achieved if the synthesis and pretreatment are done properly. Pitfalls in sample syntheses for both metal doped and bridged sorbents are pointed out in the report; deviations from the synthesis and pretreatment conditions will lead to diminished or no spillover effects. Due to the high bulk densities of zeolites, metal doped zeolites are shown to be most promising for achieving high volumetric storage capacities by spillover. Kinetics of both spillover and reverse spillover (i.e., desorption) at ambient temperature are also studied. This report summarizes the progress made in the project.

X-ray radiography measurements of diesel spray structure at engine-like ambient density.  

Science Conference Proceedings (OSTI)

X-ray radiography has been used to examine the dependence of the near-nozzle fuel distribution of diesel sprays on injection pressure and ambient density. Measurements of sprays from two nozzles with different geometries, one extensively hydroground and the other largely non-hydroground, have been obtained to show how nozzles of different geometries respond to changes in ambient density and rail pressure. The spray penetration near the nozzle demonstrates little dependence on ambient density but a strong dependence on rail pressure. Comparison of these results with standard correlations in the literature show that, in the near-nozzle region examined in this study, the penetration is expected to show little dependence on ambient density. The spray width becomes much larger for both nozzles as the ambient density increases. Rescaling the axial position by the square root of the density ratio between the fuel and the ambient gas accounts for the trends in spray width with ambient density for both nozzles. The radiography data can also be examined to determine the relative trends in the steady-state, mass-averaged axial velocity of the spray. The velocity decays more rapidly with axial distance as the ambient density increases. Rescaling the axial position also accounts for the trend of velocity decay with ambient pressure.

Formic Acid Dehydrogenation on Au-Based Catalysts at Near-Ambient Temperatures  

DOE Green Energy (OSTI)

Formic acid (HCOOH) is a convenient hydrogen carrier in fuel cells designed for portable use. Recent studies have shown that HCOOH decomposition is catalyzed with Ru-based complexes in the aqueous phase at near-ambient temperatures. HCOOH decomposition reactions are used frequently to probe the effects of alloying and cluster size and of geometric and electronic factors in catalysis. These studies have concluded that Pt is the most active metal for HCOOH decomposition, at least as large crystallites and extended surfaces. The identity and oxidation state of surface metal atoms influence the relative rates of dehydrogenation (HCOOH {yields} H{sub 2} + CO{sub 2}) and dehydration (HCOOH {yields} H{sub 2}O + CO) routes, a selectivity requirement for the synthesis of CO-free H{sub 2} streams for low-temperature fuel cells. Group Ib and Group VIII noble metals catalyze dehydrogenation selectively, while base metals and metal oxides catalyze both routes, either directly or indirectly via subsequent water-gas shift (WGS) reactions.

NETL: Ambient Monitoring - Southern Fine Particulate Monitoring Project  

NLE Websites -- All DOE Office Websites (Extended Search)

Southern Fine Particulate Monitoring Project (SRI) Southern Fine Particulate Monitoring Project (SRI) Southern Research Institute (SRI), Birmingham, AL, is operating a research station in North Birmingham for monitoring fine particulate matter (PM2.5) that exists in that part of the Deep South. The station will be a core PM2.5 mass monitoring and chemical speciation station in the nationwide EPA PM2.5 network. As such, it will be a complement and supplement to DOE-NETL's other ongoing projects for monitoring fine particulate matter in the upper Ohio River valley. Locating additional monitoring equipment in the Deep South will fill an important gap in the national particulate monitoring effort. The region's topography, weather patterns, and variety of emission sources may affect the chemical make-up and airborne transport of fine particles in ways that are different than in other parts of the country. The project's results will support DOE's comprehensive program to evaluate ambient fine particulate matter through better understanding of the chemical and physical properties of these materials.

NETL: Ambient Monitoring - Contribution of Semi-volatile Organic Material  

NLE Websites -- All DOE Office Websites (Extended Search)

Semi-volatile Organics in PM Semi-volatile Organics in PM This project is a cooperative effort between Brigham Young University (BYU) and researchers from the DOE-NETL Office of Science and and Engineering Research to determine the contribution of semi-volatile particulate organic compounds (SVOC) to total ambient suspended fine particulate mass at the NETL-Pittsburgh air monitoring facility. Project funding comes from DOE‘s University Coal Research (UCR) program. The hypothesis of the project is that fine particulate mass will be significantly under-determined in urban environments using single filter samplers such as the PM2.5 Federal Reference Method (FRM) because of the loss of semi-volatile organic compounds (SVOC) from the particles during sampling and storage. It is postulated that fine particulate mass, including the semi-volatile fine particulate organic species, are an appropriate surrogate for the components of fine particles which are associated with observed mortality and morbidity effects in epidemiological studies. Further, it is postulated that the most important fraction of the semi-volatile organic material with respect to exacerbation of health problems will be semi-volatile secondary compounds formed from reactions of volatile organic material with ozone and nitrogen oxides. Under-determination of these semi-volatile species will tend to over emphasize the importance of non-volatile fine particulate components such as sulfate or may reduce the significance of correlations with measured health effects.

Subarctic atmospheric aerosol composition: 1. Ambient aerosol characterization  

SciTech Connect

Sub-Arctic aerosol was sampled during July 2007 at the Abisko Research Station Stordalen field site operated by the Royal Swedish Academy of Sciences. Located in northern Sweden at 68º latitude and 385 meters above sea level (msl), this site is classified as a semi-continuous permafrost mire. Number density, size distribution, cloud condensation nucleus properties, and chemical composition of the ambient aerosol were determined. Backtrajectories showed that three distinct airmasses were present over Stordalen during the sampling period. Aerosol properties changed and correlated with airmass origin to the south, northeast, or west. We observe that Arctic aerosol is not compositionally unlike that found in the free troposphere at mid-latitudes. Internal mixtures of sulfates and organics, many on insoluble biomass burning and/or elemental carbon cores, dominate the number density of particles from ~200 to 2000 nm aerodynamic diameter. Mineral dust which had taken up gas phase species was observed in all airmasses. Sea salt, and the extent to which it had lost volatile components, was the aerosol type that most varied with airmass.

Effects of ambient conditions and fuel composition on combustion stability  

DOE Green Energy (OSTI)

Recent regulations on NO, emissions are promoting the use of lean premix (LPM) combustion for industrial gas turbines. LPM combustors avoid locally stoichiometric combustion by premixing fuel and the air upstream of the reaction region, thereby eliminating the high temperatures that produce thermal NO.. Unfortunately, this style of combustor is prone to combustion oscillation. Significant pressure fluctuations can occur when variations in heat release periodically couple pressure to acoustic modes in the combustion chamber. These oscillations must be controlled because resulting vibration can shorten the life of engine hardware. Laboratory and engine field testing have shown that instability regimes can vary with environmental conditions. These observations prompted this study of the effects of ambient conditions and fuel composition on combustion stability. Tests are conducted on a sub-scale combustor burning natural gas, propane, and some hydrogen/hydrocarbon mixtures. A premix, swirl-stabilized fuel nozzle typical of industrial gas turbines is used. Experimental and numerical results describe how stability regions may shift as inlet air temperature, humidity, and fuel composition are altered. Results appear to indicate that shifting instability instability regimes are primarily caused by changes in reaction rate.

Bright Water- hydrosols, water conservation and climate change  

E-Print Network (OSTI)

Since air-water and water-air interfaces are equally refractive, cloud droplets and microbubbles dispersed in bodies of water reflect sunlight in much the same way. The lifetime of sunlight-reflecting microbubbles, and hence the scale on which they may be applied, depends on Stokes Law and the influence of ambient or added surfactants. Small bubbles backscatter light more efficiently than large ones, opening the possibility of using highly dilute micron-radius hydrosols to substantially brighten surface waters. Such microbubbles can noticeably increase water surface reflectivity, even at volume fractions of parts per million and such loadings can be created at an energy cost as low as J m-2 to initiate and milliwatts m-2 to sustain. Increasing water albedo in this way can reduce solar energy absorption by as much as 100 W m-2, potentially reducing equilibrium temperatures of standing water bodies by several Kelvins. While aerosols injected into the stratosphere tend to alter climate globally, hydrosols can be...

SOIL HEALTH AND SOIL QUALITY: A REVIEW  

E-Print Network (OSTI)

Soil health is defined as the continued capacity of soil to function as a vital living system, by recognizing that it contains biological elements that are key to ecosystem function within land-use boundaries (Doran and Zeiss, 2000; Karlen et al., 2001). These functions are able to sustain biological productivity of soil, maintain the quality of surrounding air and water environments, as well as promote plant, animal, and human health (Doran et al., 1996). The concept of soil quality emerged in the literature in the early 1990s (Doran and Safely, 1997; Wienhold et al., 2004), and the first official application of the term was approved by the Soil Science Society of America Ad Hoc Committee on Soil Quality (S-581) and discussed by Karlen et al., (1997). Soil quality was been defined as ‘‘the capacity of a reference soil to function, within natural or managed ecosystem boundaries, to sustain plant and animal productivity, maintain or enhance water and air quality, and support human health and habitation.’ ’ Subsequently the two terms are used interchangeably (Karlen et al., 2001) although it is important to distinguish that, soil quality is related to soil function (Karlen et al., 2003; Letey et al, 2003), whereas soil

COMPARATIVE EVALUATION OF AMBIENT FINE PARTICULATE MATTER (PM2.5) DATA OBTAINED FROM URBAN AND RURAL MONITORING SITES ALONG THE UPPER OHIO RIVER VALLEY  

Science Conference Proceedings (OSTI)

Advanced Technology Systems, Inc. (ATS), with Desert Research Institute (DRI) and Ohio University as subcontractors, was contracted by the NETL in September 1998 to manage the Upper Ohio River Valley Project (UORVP), which included the establishment and operation of four ambient air monitoring sites located in the Upper Ohio River Valley (UORV). Two urban and two rural monitoring sites were included in the UORVP. The four sites selected for the UOVRP were collocated at existing local and/or state air quality monitoring stations. The goal of the UORVP was to characterize the nature and composition of PM{sub 2.5} and its precursor gases. In the process, the objectives of the UORVP were to examine the ambient air concentrations of PM{sub 2.5} as compared with the promulgated PM{sub 2.5} standards, the geographical, seasonal and temporal variations of ambient air concentrations of PM{sub 2.5}, the primary chemical constituents of PM{sub 2.5}, and the correlations between ambient air concentrations of PM{sub 2.5} and its precursor gases, other gaseous pollutants and meteorological parameters. A variety of meteorological and pollutant measurement devices, including several different PM{sub 2.5} samplers that provided either real-time or integrated concentration data, were deployed at the monitoring sites. The frequency of integrated sampling varied throughout the UORVP study period and was as follows: ''Intensive'' sampling periods were defined as periods in which samples were collected on a relatively frequent basis (ranged from 6-hour integrated samples collected round-the-clock to one 24-hour integrated sample collected every third day). ''Background'' sampling periods were defined as periods in which 24-hour integrated samples were collected every third or sixth day.

Stability Issues in Ambient-Temperature Passive Magnetic Bearing Systems  

DOE Green Energy (OSTI)

The ambient-temperature passive magnetic bearing system developed at the Lawrence Livermore National Laboratory achieves rotor-dynamic stability by employing special combinations of levitating and stabilizing elements. These elements, energized by permanent magnet material, create the magnetic and electrodynamic forces that are required for the stable levitation of rotating systems, such as energy-storage flywheels. Stability criteria, derived from theory, describe the bearing element parameters, i.e., stiffnesses and damping coefficients, that are required both to assure stable levitation (''Earnshaw-stability''), and stability against whirl-type rotor-dynamic instabilities. The work described in this report concerns experimental measurements and computer simulations that address some critical aspects of this overall stability problem. Experimentally, a test device was built to measure the damping coefficient of dampers that employ eddy currents induced in a metallic disc. Another test device was constructed for the purpose of measuring the displacement-dependent drag coefficient of annular permanent magnet bearing elements. In the theoretical developments a computer code was written for the purpose of simulating the rotor-dynamics of our passive bearing systems. This code is capable of investigating rotor-dynamic stability effects for both small-amplitude transient displacements (i.e., those within the linear regime), and for large-amplitude displacements, where non-linear effects can become dominant. Under the latter conditions a bearing system that is stable for small-amplitude displacements may undergo a rapidly growing rotor-dynamic instability once a critical displacement is exceeded. A new result of the study was to demonstrate that stiffness anisotropy of the bearing elements (which can be designed into our bearing system) is strongly stabilizing, not only in the linear regime, but also in the non-linear regime.

Vitrification of high level nuclear waste inside ambient temperature disposal containers using inductive heating: The SMILE system  

Science Conference Proceedings (OSTI)

A new approach, termed SMILE (Small Module Inductively Loaded Energy), for the vitrification of high level nuclear wastes (HLW) is described. Present vitrification systems liquefy the HLW solids and associated frit material in large high temperature melters. The molten mix is then poured into small ({approximately}1 m{sup 3}) disposal canisters, where it solidifies and cools. SMILE eliminates the separate, large high temperature melter. Instead, the BLW solids and frit melt inside the final disposal containers, using inductive heating. The contents then solidify and cool in place. The SMILE modules and the inductive heating process are designed so that the outer stainless can of the module remains at near ambient temperature during the process cycle. Module dimensions are similar to those of present disposal containers. The can is thermally insulated from the high temperature inner container by a thin layer of refractory alumina firebricks. The inner container is a graphite crucible lined with a dense alumina refractory that holds the HLW and fiit materials. After the SMILE module is loaded with a slurry of HLW and frit solids, an external multi-turn coil is energized with 30-cycle AC current. The enclosing external coil is the primary of a power transformer, with the graphite crucible acting as a single turn ``secondary.`` The induced current in the ``secondary`` heats the graphite, which in turn heats the HLW and frit materials. The first stage of the heating process is carried out at an intermediate temperature to drive off remnant liquid water and water of hydration, which takes about 1 day. The small fill/vent tube to the module is then sealed off and the interior temperature raised to the vitrification range, i.e., {approximately}1200C. Liquefaction is complete after approximately 1 day. The inductive heating then ceases and the module slowly loses heat to the environment, allowing the molten material to solidify and cool down to ambient temperature.

Pilot project of biogas production from pig manure and urine mixture at ambient temperature in Ventanilla (Lima, Peru)  

Science Conference Proceedings (OSTI)

Parque Porcino de Ventanilla has an extension of 840 ha with 2200 farmers dedicated to pig production. There is a lack of services in the area (i.e., water supply, electricity, or waste collection). Anaerobic treatment of pig manure would replace current dumping and incineration, reducing environmental pollution and hazards to public health, as well as providing an organic fertilizer and biogas. The objective of the present work was to study the viability of ambient temperature anaerobic digestion of pig manure diluted in urine, by means of on-site pilot scale reactors. The final goal was to establish design parameters for anaerobic digesters to be implemented; since it was part of a project to improve life conditions for the farmers through the incorporation of better management techniques. Experiments were carried out in a low-cost pilot plant, which consists of three anaerobic digesters (225 L total volume), without heating or agitation, placed in a greenhouse. The start-up of the digestion process was performed with a mixture of temperature adapted pig manure-sludge and fresh rumen, and showed a good performance regardless of the dilution of pig manure with water or urine, which is a key parameter due to the scarcity of water in the area under study.

Ni-MH battery modelling for ambient intelligence applications  

E-Print Network (OSTI)

Mobile devices, like sensor networks and MEMS actuators use mobile power supplies to ensure energy for their operation. These are mostly batteries. The lifetime of the devices depends on the power consumption and on the quality and capacitance of the battery. Though the integrated circuits and their power consumption improve continually, their clock frequency also increases with the time, and the resultant power consumption seems not to vary, or slightly increase. On the other hand, the properties of batteries are developing much slower, necessitating the optimization of their usage on system level.

Downhole steam quality measurement  

DOE Patents (OSTI)

The present invention relates to an empirical electrical method for remote sensing of steam quality utilizing flow-through grids which allow measurement of the electrical properties of a flowing two-phase mixture. The measurement of steam quality in the oil field is important to the efficient application of steam assisted recovery of oil. Because of the increased energy content in higher quality steam it is important to maintain the highest possible steam quality at the injection sandface. The effectiveness of a steaming operation without a measure of steam quality downhole close to the point of injection would be difficult to determine. Therefore, a need exists for the remote sensing of steam quality.
