Superfund Site Profile
The Koppers Co., Inc. (Charleston Plant) site is located in Charleston, South Carolina. It includes the area where the Koppers Company operated a wood treatment facility from 1940 to 1978. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1994 because of contaminated groundwater, sediment, soil and surface water resulting from facility operations. EPA, the South Carolina Department of Health and Environmental Control (SCDHEC) and Beazer East, Inc., 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 residents and businesses to the public water supply. By treating and monitoring groundwater, placing institutional controls on the site property and undertaking Five-Year Reviews, EPA, SCDHEC and the site’s PRP continue to protect people and the environment from site contamination.
