| Abstract |
The Kimberton site is in Chester County, Pennsylvania, near the Philadelphia metropolitan area. The site encompasses an industrial production plant currently owned by Monsey Products Company, Inc., and adjacent properties within the neighboring Village of Kimberton. Water quality testing since 1981 has revealed numerous area domestic and commercial potable well water supplies contaminated with VOCs. An EPA investigation in the spring of 1982 revealed the presence of organics, including TCE and DCE, in local ground water, surface water, and soil. In mid 1982, fifty seven, 55-gallon drums from an abandoned onsite septic system were excavated, removed, and disposed of offsite. In 1984 a remedial action program was initiated to excavate, remove, and dispose of approximately 2,050 cu yds of soil from three former lagoon areas that were highly contaminated with VOCs. In 1985, 67 residential and commercial wells were sampled and found to contain various concentrations of TCE, DCE, and vinyl chloride. The selected remedial action for this site includes the continued provision of alternate water supplies through GAC treatment system and/or potable water supply storage tanks; pumping and treatment of ground water using an air stripping system with onsite discharge; long-term ground water monitoring; collection and treatment of surface water at the local ground water discharge point using an air stripping system. |
