The 20-acre Chemtronics, Inc. site is located in Swannanoa, North Carolina. The site includes an industrial area affected by waste disposal practices associated with manufacturing operations, including explosives manufacturing, thought to have taken place on site from 1952 to 1971. EPA placed the site on the Superfund program�s National Priorities List (NPL) in 1983 because of contaminated groundwater and soil resulting from waste disposal practices. Manufacturing activities at the site ended in 1994. EPA, the North Carolina Department of Natural Resources and Environment (NCDENR), and the site�s potentially responsible parties (PRPs) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. By treating and monitoring groundwater, addressing soil contamination, evaluating options for additional cleanup and conducting Five-Year Reviews, EPA, NCDENR and the site�s PRPs continue to protect people and the environment from site contamination.
