| Abstract |
The Department of Energy and the U.S. Environmental Protection Agency have been involved in designing and evaluating a pilot field demonstration of reductive anaerobic biological in-situ treatment technologies (RABITT) for use as a standard remedial technology for chloroethene contamination. Innovative site characterization techniques have been utilized to identify the hydraulics of the site and in particular the vertical distribution of relative hydraulic conductivities. Direct extraction of intact frozen cores has been utilized to determine the vertical distributions of contaminants in the pore spaces and on the solid matrix of site material. The combination of these techniques along with standard site characterization methods has been used to develop a three-dimensional picture of the site with vertical resolutions down to 0.5 ft (15 cm). This information has then been used to evaluate different scenarios for nutrient/electron donor delivery at the site, and when used with appropriate transport and flow codes was used to exclude designs which did not allow for significant mixing of donor and contaminants, or which did not efficiently deliver nutrients/donor to all contaminated zones. |
