Superfund Site Profile
The 59.5-acre Koppers Co., Inc. (Morrisville Plant) site is located in Morrisville, North Carolina. It includes the area where a wood-treating facility operated from 1968 to 1975. EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1989 because of contaminated groundwater, soil and surface water resulting from facility operations. EPA, the North Carolina Department of Environment and Natural Resources (NCDENR), 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 nearby residences and businesses to the public water supply. By treating groundwater, evaluating additional cleanup activities and undertaking Five-Year Reviews, EPA, NCDENR and the site’s PRP continue to protect people and the environment from site contamination. After cleanup, EPA took a portion of the site, the 33-acre Unit Structures, Inc. property, off the NPL in 2000.
