Abstract

The report contains the results of the initial feasibility study for a research program undertaken to develop the technology needed to use fiber optics for monitoring groundwater contaminants. The technology appears especially well suited to the requirements of detection monitoring where a few indicator parameters can be measured continuously by sensors placed down small-diameter monitoring wells. Data are generated at a remote, centrally located fluorimeter, connected to the sampling sites by inexpensive optical fibers. The analytical method is laser-induced fluorescence which gives the desired sensitivity. The optrode, a chemical system and/or a mechanical device at the distal end of a fiber optic, furnishes the needed specificity. Various fiber and optrode configurations have been evaluated and their applications to groundwater monitoring are discussed. Feasibility is shown for physical measurements such as temperature, pressure and pH. Chemical detection and quantification of the actinides, inorganic and organic chlorides, sulfates, alcohols, aldehydes, pesticides and tracer materials are presented. Finally, it is shown that the need for smaller diameter wells (as compared to conventional sampling methods), and the ability to make up to 50 unattended in situ measurements, using a reasonably priced centralized fluorometer system connected to the sampling sites by inexpensive optical fibers, resultsmore » in acceptable economy.« less

Process, product, and waste-stream monitoring with fiber optics

Conference Milanovich, F P ; Hirschfeld, T

Fiber optic technology, motivated by communications and defense applications, has advanced significantly the past ten years. In particular, advances have been made in visible radiation transmission efficiency with concurrent reductions in fiber size, weight, and cost. Researchers at the Lawrence Livermore National Laboratory (LLNL) coupled these advances in fiber optic technology with analytical fluorescence analysis to establish a new technology - remote fiber fluorimetry (RFF). Laser-based RFF offers the potential to measure and monitor from one central and remote laboratory, on-line, and in near real time, trace (ppM) to substantial (g/L) concentrations of selected chemical species in typical process, product,more »« less

Feasibility of using fiber optics for monitoring groundwater contaminants. II. Organic chloride optrode

Technical Report Milanovich, F ; Hirschfeld, T ; Miller, H ; ...

Fiber optics, lasers, chemistry, optrodes, optics and spectroscopy have been integrated to form the new concept of remote fiber spectroscopy. This technology permits the development of ductile probes to detect and monitor groundwater contaminants. The key to this concept is the optrode, a fiber termination with preselected chemical and physical properties. The optrode is attached to the distal end of the fiber so that specific, sensitive analyses of groundwater contaminants can be made. A single fiber is used for both excitation and for collection of the return signal thus keeping the sensor small and optically simple. This report contains themore »« less
In situ detection of organic molecules: Optrodes for TCE (trichloroethylene) and CHCl sub 3

Technical Report Angel, S. M. ; Langry, K. C. ; Ridley, M. N.

We have developed new absorption-based chemical indicators for detecting chloroform (CHCl{sub 3}) and trichloroethylene (TCE). These indicators were used to make very sensitive optical chemical sensors (optrodes) for each of these two contaminants. Concentrations below 10 ppb can be accurately measured using these sensors. Furthermore, they are selective and do not response to similar contaminants commonly found with TCE and CHCl{sub 3} in contaminated groundwater. In addition, the sensor response is linearly proportional to the chemical concentration. In this report, we describe the details of this optrode and the putative reaction sequences of the indicator chemistries with CHCl{sub 3} andmore »« less

Geochemical Monitoring System and Network for Complex Subsurface Matrices

Technical Report Delgado Alonso, Jesus

Soil and groundwater chemistry have traditionally been characterized via laboratory analysis of "grabbed" samples – either samples of the soil itself or gas samples, and groundwater. In situ sensors that monitor chemical parameters, including nutrients in either soil or groundwater, are subject to numerous limitations, in particular for continuous monitoring: a requirement for consumables (mainly for nutrient monitoring), significant maintenance, bulky instrumentation, and cost. There is a clear need for a single monitoring system capable of collecting data for a range of biochemical parameters of interest, at a reasonable cost and with low maintenance.

Development of Novel, Simple, Multianalyte Sensors for Remote Environmental Analysis

Technical Report Asher, Sanford A

We will develop simple, inexpensive new chemical sensing materials which can be used as visual color test strips to sensitively and selectively report on the concentration and identity of environmental pollutants such as cations of Pb, U, Pu, Sr, Hg, Cs, Co as well as other species. We will develop inexpensive chemical test strips which can be immersed in water to determine these analytes in the field. We will also develop arrays of these chemical sensing materials which will be attached to fiber optic bundles to be used as rugged multichannel optrodes to simultaneously monitor numerous analytes remotely in hostilemore »« less
