About the Superfund Redevelopment Initiative
This nationally coordinated effort provides EPA and its partners with a process to return Superfund sites to productive use. Learn more at Superfund Redevelopment Initiative.
Redevelopment at the Site
The Sangamo Weston, Inc./Twelve-Mile Creek/Lake Hartwell Polychlorinated Biphenyls (PCB) Contamination Superfund site is located in Pickens, South Carolina. The 224-acre site includes the location of a former manufacturing plant, six waste disposal areas, and a portion of Twelve-Mile Creek and Lake Hartwell. Sangamo Weston, Inc. owned and operated a capacitor manufacturing plant on site from 1955 to 1987. Waste handling practices resulted in contamination on site. EPA added the site to the Superfund program’s National Priorities List (NPL) in 1990.
Cleanup activities included removal and treatment of soil and groundwater; groundwater, fish tissue and sediment monitoring; fish consumption guidelines; and a fish advisory public education and awareness program. Fish advisories remain in effect for fish caught from Lake Hartwell and Twelve-Mile Creek. After completing cleanup activities, EPA deleted portions of the site from the NPL. In a merger, Sangamo Weston, Inc. became Schlumberger Technology Corporation, and donated part of the property to the City of Pickens in 1999.
A portion of the Sangamo Weston, Inc./Twelve-Mile Creek/Lake Hartwell PCB Contamination site is in recreational reuse. The majority of the manufacturing plant area and the six waste disposal areas are vacant. Residential land uses and undeveloped land surround the site. The City of Pickens redeveloped the area into a public recreation complex. Following cleanup activities, the manufacturing plant area supports industrial uses and the six areas support residential land uses.
Economic Activity at the Site
As of December 2018, EPA did not have economic data related to on-site businesses, or economic data were not applicable due to site use. View information about redevelopment economics at Superfund sites.
