SITE BACKGROUND

The Sangamo Weston, Inc./Twelve-Mile Creek/Lake Hartwell PCB Contamination site includes the area where Sangamo Weston, Inc. owned and operated a capacitor manufacturing plant from 1955 to 1987. The site also includes six areas where operations disposed of waste as well as areas downstream from the site, including a portion of Twelve-Mile Creek and Lake Hartwell. EPA placed the site on the National Priorities List (NPL) in 1990 because of contaminated debris, groundwater, sediment, sludge, soil and fish tissue resulting from facility operations.

EPA, the South Carolina Department of Health and Environmental Control (SCDHEC) and Schlumberger Technology Corporation, the site’s potentially responsible party (PRP), have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. A water line connects residences and businesses to the public water supply. By treating and monitoring groundwater and undertaking Five-Year Reviews, EPA, SCDHEC and the site’s PRP continue to protect people and the environment from site contamination.
