The former Absco scrap yard had been used for 40 years, and previous to that the location had been used as a rail yard. As a result of this long history of industrial use, site soils were contaminated with polychlorinated biphenyls (PCBs), petroleum, lead, and other metals. The site was designated as a Superfund site and the former owner was under a consent order agreement with the United States Environmental Protection Agency (USEPA) and the Pennsylvania Department of Environmental Protection (PADEP) to remediate the property. Once sold, the remediation became the responsibility of the new owner prior to plans for redevelopment. The untreated soil was found to be hazardous for lead, containing total lead concentrations in excess of 3,000 parts per million. EnviroBlend® was added at 1% to 3% by weight of the soil.
Post-treatment, the soil of the former Absco scrap yard was transported off-site and disposed of at a non-hazardous Subtitle D landfill. This work was conducted in close contact with USEPA and the agency approved the remediation and disposal option upon its completion. The client found the use of EnviroBlend to be a technically sound, environmentally acceptable, and cost-effective solution.
