Notes:
Ground water in a shallow glacial till aquifer and a deeper weathered shale aquifer at a site near Rock Creek, Ohio has been contaminated with trichloroethylene (TCE). Evaluation of remedial alternatives indicated that a system of subsurface drains would be most effective for decontaminating the shallow ground water. The performance of the proposed subsurface drainage system for the shallow aquifer was simulated using finite-element flow and transport models. Model results indicate that the drains should reduce TCE concentration in the shallow aquifer to about 8 ppb in approximately 24 years.A single extraction well was the selected alternative to remediate trichloroethylene concentrations in the deeper weathered shale aquifer. The performance of the proposed well was analyzed by an analytical method. Results of the analysis indicated that the extraction well should reduce contamination in less time than required for the shallow glacial till aquifer. Validation of the predicted performance of the remedial system will be assessed following installation of the system and collection of field data.
