Martin Aaron Superfund Site Camden, New Jersey

Liberty personnel provided remediation planning, permitting, engineering, and construction oversight services for a large-scale soil remediation project at the 6.5-acre Martin Aaron Superfund Site located in Camden, New Jersey. The site was used as a former drum recycling business and a former tannery operation that covered the entire city block. The remediation project involved the excavation and disposal of approximately 100,000 tons of soil contaminated with Volatile Organic Compounds, PCBs, and Arsenic. The wastes classifications included TSCA, RCRA, and Non-Hazardous wastes. Remedial activities included sheet piling to form excavation cells, excavation dewatering, treatment of the construction water, discharge to groundwater and sewer conveyance systems, and engineered capping of residual soil contamination that was not excavated


Liberty services over 9-year period included:

  • Preparation of Remediation Plans including a Remedial Action Work Plan, Traffic Control Plan, Construction Survey and Vibration Monitoring Plan, and Quality Assurance Project Plan.
  • Preconstruction activities including a sewer truck investigation, preconstruction survey, NJPDES and TWA permit equivalency applications that included full design packages, oversight of demolition activities of on-site structures, and mapping of subsurface structures.
  • Construction Quality Assurance Services (24 months) including excavation and backfilling oversight, waste disposal tracking, post-excavation soil sampling and analytical data review, and vibration monitoring of an on-site 3-story adjacent building, a 110-year-old sewer trunk, and a fiber optic line.
  • Regulatory documentation of the remediation including preparation of a Remedial Action Report, As-built Drawing Set, and Deed Notices for properties where the engineered caps were constructed.

The support contributed by Liberty procured the approval of the US Environmental Protection Agency (Region 2), Army Corp of Engineers (Philadelphia and Kansas City), New Jersey Department of Environmental Protection, and the Camden County Municipal Utilities Authority.
