  • The objective of this document is to examine the use of a phased approach to characterizing and monitoring (C&M) natural attenuation processes and enhanced attenuation processes and to identify promising tools and techniques by which to accomplish the C&M. We will investigate developing techniques, such as molecular-based assessment tools, and existing tools that traditionally have not been used for monitoring the performance of environmental remediation technologies. Case studies will be used to provide examples of how non-traditional methods are being employed as characterization and monitoring tools to support MNA and EA. The document is not focused on a specific groupmore » of readers but rather is broadly directed with the intent that readers may gain information useful to their purposes. Thus, regulators may see some future characterization and monitoring techniques; end users may find novel ways to make MNA or EA more effective or efficient at their site; researchers may identify new areas for development or new and better combinations of existing methods. One consequence of this broad approach is that some readers may find certain sections either too rudimentary or too advanced for their needs. Hopefully, all will be able to use at least some of the document.« less
  • This protocol is designed to evaluate the fate in ground water of chlorinated aliphatic hydrocarbons and/or fuel hydrocarbons. The data collected under this protocol can be used to compare the relative effectiveness of other remedial options and natural attenuation. This protocol should be used to evaluate whether monitored natural attenuation by itself or in conjunction with other remedial technologies is sufficient to achieve site-specific remedial objectives. Understanding the contaminant flow field in the subsurface is essential for a technically justified evaluation of a monitored natural attenuation remedial option; therefore, use of this protocol is not appropriate for evaluating monitored naturalmore » attenuation at sites where the contaminant flow field cannot be determined with an acceptable degree of certainty (e.g., complex fractured bedrock, karst aquifers).« less
  • A field program for site characterization of targeted study areas at the Dover Air Force Base was conducted between January 16, 1995, and March 9, 1995. The stated objectives of the investigation, `to characterize the stratigraphy, depth to groundwater, groundwater flow directions, and the vertical and horizontal distribution of contaminants within the accelerated anaerobic biodegradation test plot and the intrinsic bioremediation test plot,` were accomplished in a phased approach. The site stratigraphy was characterized based on the interpretation and correlation of recent cone penetrometer technology (CPT) logs with existing well logs. Depth to water and aerial groundwater flow directions acrossmore » the study area were determined from contoured water-level measurements in new piezometers and existing monitor wells. The extent of contamination, both vertical and horizontal, was determined based on `StrataProbe` groundwater sampling and laboratory analysis for selected target constituents. This report summarizes the work conducted, describes the details of the effort, and reports the conclusions. The activity portion of this report is divided into sections corresponding to the three phases of the fieldwork described in the work plan: CPT logging, soil and groundwater sampling, and piezometer installation.« less
  • During 1992-97, the U.S. Geological Survey investigated the natural attenuation of chlorinated volatile organic compounds (VOC`s) in a contaminant plume that discharges from a sand aquifer to a freshwater tidal wetland along the West Branch Canal Creek at Aberdeen Proving Ground, Maryland. Characterization of the hydrogeology and geochemistry along flowpaths in the wetland area and determination of the occurrence and rates of biodegradation and sorption show that natural attenuation could be a feasible remediation method for the contaminant plume that extends along the West Branch Canal Creek.
