puchack well field

WEST OF US 130; SOUTH OF STATE HWY 90

The Puchack Well Field Superfund Site consists of six public supply wells owned and operated by the City of Camden, located in Pennsauken Township, Camden County, New Jersey. A seventh public water supply well was reportedly destroyed during construction of the Betsy Ross Bridge that connects New Jersey and Pennsylvania, over the Delaware River. Contamination was first detected at Puchack in the early 1970s with the presence of trichloroethane (TCE), 1,2-dichloroethane (1,2-DCA), tetrachlorethane (PCE), and chromium compounds in well No. 6. Further sampling indicated the presence of total and hexavalent chromium at concentrations above the health based level, which resulted in the well being removed from service in 1975. Contamination continued to spread to remaining Puchack supply wells, and all wells were removed from service in the mid 1980s, except well No. 1, which the New Jersey Department of Environmental Protection (NJDEP) allowed to be pumped at approximately 800,000 gallons per day, to help prevent the plume from spreading to other public supply wells. Well No. 1 was removed from service in May 1998. The area encompassed by the Puchack Well Field is approximately 450,000 square feet. The Puchack Well Field Site was included on the National Priorities List (NPL), March 6, 1998. Site Responsibility: The Site is Federal lead, and is currently being addressed by a combination of Federal and State actions.
