Superfund Site Profile
The Delaware City PVC Plant site occupies 400 acres, consisting of a polyvinyl chloride (PVC) manufacturing facility currently owned and operated by Formosa Plastics Corp. of Delaware and a surrounding contaminated groundwater plume. The plant was built in 1966 by Stauffer Chemical Company, which used earthen lagoons and pits to dispose of PVC waste and sludge. Stauffer Chemical sold the PVC plant to Formosa Plastics Corporation in May 1981 Groundwater which was used locally for drinking water and agricultural purposes, was found to be contaminated with chemicals emanating from the plant. Soils associated with earthen lagoons were also found to be contaminated.
