This site previously served as a research facility where dried wastewater sludge was used as fill material during site development in the 1960s. The sludge contained hazardous levels of arsenic and other contaminant constituents at levels above the New Jersey Department of Environmental Protection’s Soil Remediation Standards. Langan provided site remediation services that addressed two Areas of Concern (AOCs) which included soil contamination associated with site-wide historic fill material and petroleum related soil impacts. Soil contamination was identified adjacent to a former 10,000-gallon diesel UST/20,000-gallon fuel oil UST area and the adjacent Chipper Process Area. An Open Public Records Act (OPRA) was requested to obtain files on previous investigations and remediation completed at the property. Langan engineers also collected soil samples to determine the extent of fill material.
