Abstract:

The objective of this remedial investigation RI is to evaluate, as part of the first operable unit for site remediation, the nature and extent of contamination as it relates to the existing public water supply wells operated by the South Adams County Water and Sanitation District. A public health endangerment assessment was conducted to identify compounds which could pose a significant health threat. These investigations have identified ground water as the major migration pathway. The six volatile organic chemicals of primary concern are 11DCE,11DCLE, T12DCE, 111TCE, TRCLE, and TCLEE. A comprehensive investigation analysis was conducted to 1 characterize the hydrogeologic system and 2 quantify the ground water flow and containment transport processes. A three dimensional ground water flow and containment transfer model was developed and calibrated on a preliminary basis to aid in projection of future TRCLE concentrations. This first operable unit RI report is not in intended to address the identity of contributing sources or their relative contributions to the contamination.
