Book excerpt: This report describes the results of groundwater and soil gas sampling conducted at the Distler Brickyard Site, Hardin County, Kentucky, June-August, 2000. The purpose of the sampling activities was to address remaining data gaps regarding the feasibility of monitored natural attenuation (MNA) for remediation of chloroethene/ane contamination. Specifically, data gaps fall into four categories: 1) effect of seasonal recharge on contaminant concentrations, 2) geochemical conditions in the Fine Grained Alluvium (FGA), 3) conditions along the flowpath between Wells GW-11 and MW-3, and 4) the extent of aerobic degradation in the Coarse Grained Alluvium (CGA). A data collection strategy composed of both groundwater sampling and passive soil vapor sampling devices (Gore-Sorbers?) was used. The Gore-Sorber? technology was used to collect data from the FGA, which because of its low hydraulic conductivity and variable saturation makes collection of groundwater samples problematic. Gore-Sorbers were deployed in 15 wells, most of them being in the FGA, and groundwater samples were collected in 17 wells, which were mostly in the CGA. Both sampling methods were utilized in a subset of wells (7) in order to determine the general comparability of results obtained from each method. Results indicate that water levels in both the FGA and CGA were higher in June-August 2000 than in October 1999, likely due to increased infiltration of precipitation through the FGA during the wetter months. Redox conditions in the FGA and downgradient CGA were iron-reducing, less reducing than in October-1999. In general, concentrations of chloroethenes/anes were higher in June-August 2000 than October 1999. Trichloroethene (TCE) was present at concentrations as high as 65 μg/L in the FGA and 19 μg/L in the CGA. This is substantially higher than the maximum concentration in October 1999 of 11 μg/L. The following conclusions were drawn from these data collection activities: 1) two potential contaminant source areas remain at the site, 2) redox conditions are less reducing than October 1999, 3) anaerobic reductive dechlorination (ARD) continues to take place in the FGA, and 4) seasonal fluctuations in recharge affect water levels, redox conditions, contaminant concentrations, and ARD reactions. Possible final remedial response actions include 1) monitored natural attenuation, 2) monitored natural attenuation with physical source removal, or 3) monitored natural attenuation with source removal via enhanced ARD. All of these remedies will require the collection of additional data in three areas: 1) the nature and extent of the GW-3/UDBW-11 source area and the flux rate and fate of contaminants from it, 2) the magnitude and timing of recharge fluctuations, and 3) the local hydraulic gradient and groundwater flow directions. Each remedy may also have specific additional data collection requirements. This document will serve as the basis for the selection of the appropriate remedy by the state and federal regulators.

Download or read book Statistical Methods for Groundwater Monitoring written by Robert D. Gibbons and published by John Wiley & Sons. This book was released on 2009-10-08 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new edition of the most comprehensive overview of statistical methods for environmental monitoring applications Thoroughly updated to provide current research findings, Statistical Methods for Groundwater Monitoring, Second Edition continues to provide a comprehensive overview and accessible treatment of the statistical methods that are useful in the analysis of environmental data. This new edition expands focus on statistical comparison to regulatory standards that are a vital part of assessment, compliance, and corrective action monitoring in the environmental sciences. The book explores quantitative concepts useful for surface water monitoring as well as soil and air monitoring applications while also maintaining a focus on the analysis of groundwater monitoring data in order to detect environmental impacts from a variety of sources, such as industrial activity and waste disposal. The authors introduce the statistical properties of alternative approaches, such as false positive and false negative rates, that are associated with each test and the factors related to these error rates. The Second Edition also features: An introduction to Intra-laboratory Calibration Curves and random-effects regression models for non-constant measurement variability Coverage of statistical prediction limits for a gamma-distributed random variable, with a focus on estimation and testing of parameters in environmental monitoring applications A unified treatment of censored data with the computation of statistical prediction, tolerance, and control limits Expanded coverage of statistical issues related to laboratory practice, such as detection and quantitation limits An updated chapter on regulatory issues that outlines common mistakes to avoid in groundwater monitoring applications as well as an introduction to the newest regulations for both hazardous and municipal solid waste facilities Each chapter provides a general overview of a problem, followed by statistical derivation of the solution and a relevant example complete with computational details that allow readers to perform routine application of the statistical results. Relevant issues are highlighted throughout, and recommendations are also provided for specific problems based on characteristics such as number of monitoring wells, number of constituents, distributional form of measurements, and detection frequency. Statistical Methods for Groundwater Monitoring, Second Edition is an excellent supplement to courses on environmental statistics at the upper-undergraduate and graduate levels. It is also a valuable resource for researchers and practitioners in the fields of biostatistics, engineering, and the environmental sciences who work with statistical methods in their everyday work.
