The State of New Jersey cited the 2-acre Swope Oil & Chemical Company in Peensauken, New Jersey in 1975 for operating without proper permits. In 1979, the State cited the company for failure to prepare, maintain, and implement a Spill Prevention, Containment and Countermeasure Plan. The Swope Oil & Chemical Company, a chemical reclamation faculty, operated from 1965 and ceased operations in late 1979. During that time, Swope Oil & Chemical Company Site processed solvents, oil, paints and other chemical compounds. Records indicate the Site buried sludge waste and discharged waste liquids and sludge into an unlined lagoon. Analysis of the groundwater underlying the site revealed the Swope Oil & Chemical Company contaminated the groundwater. Approximately, 17,000 people reside in the area and depend on groundwater from municipal wells, which is currently inactive.
Volatile organic compounds (VOCs) contaminate the groundwater. Polychlorinated biphenyls (PCBs), volatile organic compounds (VOCs), phthalates and metals contaminate the surface soil.
The potentially responsible parties (PRPs) — Swope Oil & Chemical Company, with EPA oversight, have removed lagoon sludge containing hazardous material and drummed waste. In addition, PRPs and EPA have placed a temporary cap over contaminated sludge lagoons to prevent further migration of contaminant and has built a security fence around the site. EPA has selected the following remedy to clean up the site. The PRPs have evacuated and disposed 24,000 tons of PCB- contaminated soil and backfilling of the soil. In addition, PRPs have removed and disposed of 70 tanks and have removed associated hazardous liquids.
In 1991, EPA determined that a soil vapor extraction system should be installed at the site to address contamination in subsurface soils. The SVE system was built and operated from September 1997 to July 2005 and removed over 21,000 pounds of contaminants from the subsurface soils. In 2006, 13 soil borings were advanced and samples from the borings were analyzed to determine if the SVE system had completely removed the subsurface contamination.
In the July 2010 Proposed Remedial Alternative Plan (PRAP), EPA has determined that while the SVE system was able to remove significant quantities of contaminants from the subsurface soils, some residual contamination remains. Therefore, EPA is proposing that the cap required by the OU1 ROD be installed along with, Monitored Natural Attenuation in the Shallow Aquifer with Monitoring of the Deep Aquifer and Institutional Controls.
