This part of land was owned by Imperial Oil Co./Champion Chemicals. The site was added to the National Priorities List of Superfund sites in 1983. The site consists of six production, storage, and maintenance buildings and 56 above-ground storage tanks. Known contamination includes PCBs, arsenic, lead and total petroleum hydrocarbons. A number of companies may have been responsible for waste oil discharges and arsenical pesticides released to a nearby stream as industrial operations date back to 1912. The area is protected by a fence that completely encloses it. This site is being addressed through Federal and State actions. Mayor Hornik of Marlboro Township, described the polluted site as "one of the worst in the country."
