The Mannheim Avenue Dump site is located in Galloway Township, New Jersey. The locality originally used the 2-acre area as a sand-and-gravel excavation operation for road construction material. After mining operations stopped in 1964, excavated portions of the site were used for waste disposal. These activities contaminated soil and groundwater with hazardous chemicals. Following immediate actions to protect human health and the environment, the site�s long-term remedy was put in place in 1994. After cleanup, EPA took the site off the Superfund program�s National Priorities List in August 2007.
