A novel pilot project implemented at a combined Superfund site in New Jersey has demonstrated substantial time and cost savings through the use of in-house personnel to conduct remedial designs (RDs) and remedial actions (RAs). By streamlining cleanup work at the two sites, 1) the community benefited from a less contaminated environment much earlier than expected, 2) groundwater remediation has been accelerated significantly by removing source material sooner, and 3) EPA has saved both time and money that can now be directed toward other cleanups. The results are documented in a September 2012 report issued by EPA entitled "South Jersey Clothing Company & Garden State Cleaners Superfund Sites--Project Management Pilot, Final Report."

The purpose of the pilot project was to demonstrate that using in-house EPA staff to conduct RD and RA activities can result in time and cost savings. This pilot is one of nine project management pilot projects being performed under the EPA Office of Solid Waste and Emergency Response Integrated Cleanup Initiative. The purpose of the initiative is to demonstrate substantial Superfund remedial process improvements through the use of regional-specific best practices and new approaches to project management.

Background

The South Jersey Clothing Company (SJCC) and Garden State Cleaners (GSC) sites are two properties located within 500 feet of each other, and were listed on the National Priorities List in 1989. The 3,000-square-foot GSC site supported a former dry cleaning business in Monotola, Bueno Borough, New Jersey that started operating in 1966. Dry cleaning operations using perchloroethene (PCE) were conducted at the site and, until 1985, wastes were discharged through pipes directly onto the ground. The nearby 1.2-acre SJCC facility started manufacturing and dry cleaning military clothing using trichloroethene (TCE) and PCE in 1940, and also discharged waste onsite. In addition, SJCC stored solvents and solvent-contaminated wastewaters onsite in leaking drums and tanks.

Activities at both sites resulted in a commingled groundwater contamination plume. The primary contaminant of concern (COC) at the SJCC site is TCE and the primary COC at the GSC site is PCE. The combined Record of Decision (ROD) called for soil vapor extraction (SVE) to address soils contaminated with volatile organic compounds (VOCs) at both sites, and a groundwater extraction and treatment system at the SJCC property to address the commingled plume. Final RA documents noted that analytical data indicated that the soil cleanup goals had been met at both sites.

The GSC property was then acquired by new owners. However, based on additional monitoring data generated from operating the groundwater remediation system, it was determined that the SVE systems had not adequately addressed the groundwater contamination sources on both properties. As a result, in September 2010, EPA amended the ROD to address the remaining contaminated soil. The amended remedy included acquiring the GSC property from the new owners, demolishing the GSC building, excavating the contaminated soil at both sites, and offsite disposal of the contaminated soil. The remedy also called for in situ treatment of soil contamination where excavation was impracticable.
