Superfund Site Profile
The Sangamo Electric Dump/Crab Orchard National Wildlife Refuge (the Refuge) is located five miles west of Marion in Williamson County, Illinois. The Refuge includes about 43,500 acres of land. The area is a wildlife refuge and is also in use for recreation, agriculture and industrial purposes. Prior to and during World War II, the U.S. Army and several contractors leased parts of the Refuge from the Department of Defense (DoD) to make bombs, land mines and other explosives as well as metal fabrication, plating, printing inks and electrical components. Several of these industries reportedly landfilled wastes from their manufacturing activities nearby, contaminating soil and groundwater with hazardous chemicals. Areas of the site are in various phases of cleanup: investigation, remediation and long-term monitoring.
