The Engelhard Corporation facility (“Engelhard”) is a RCRA Corrective Action facility. The site was nominated based on its long history, type and nature of volatile organic chemical presence, and performance of the ongoing ground water remedy. Initial site investigation and remedial activities have been conducted at Engelhard since the mid 1980’s. The ground water contaminant plume consisting of tetrachloroethene (PCE) and 1,1,1-trichloroethane (TCA) have migrated beyond the property boundary. A Corrective Action consent order was signed by Engelhard facility and EPA in 1993.
