Superfund Site: MALVERN TCE

Superfund Site Profile

EPA Reviews Cleanup

A new Five-year review for the site was completed in September 2015. Five-year reviews provide an opportunity to evaluate the implementation and performance of a remedy to determine whether it remains protective of human health and the environment.


Malvern TCE, located in East Whiteland Township, Chester County, Pennsylvania, operated as a solvent reclamation facility from 1952 to 1992.  The Site is in a wooded area surrounded by residential and undeveloped areas bordering the property to the west, north and east.  The site consists of a main plant area (MPA) connected to a former disposal area (FDA) by a narrow meadow corridor. 

A portion of the Site is owned and operated by Chemclene Corporation, which until a fire occurred in 1999, sold hydrogen peroxide and industrial cleaning solvents.  These solvents were used by local industries for degreasing metal parts and other cleaning purposes. Chemclene used a distillation process to remove impurities from the previously used solvents which were then returned to a customer for reuse or held in bulk storage by Chemclene for resale.

Prior to 1976, sludge from the distillation process was disposed in the wooded area, also known as the former disposal area.  The former processing, chemical storage, and waste management practices at the property have lead to solvent contamination in the soil and ground water.

Sources of soil and ground water contamination are related to two areas at the Site; the main plant area and the former disposal area located 1,900 feet southeast of the main plant.

Chemclene took several measures to clean up the site from 1982 until 1987, following the detection of soil and ground water contamination in 1980, with the oversight of the Pennsylvania Department of Environmental Protection (PADEP). As an operating hazardous waste facility, Chemclene signed an agreement with EPA in 1987 to continue the cleanup. When the company failed to carry out the agreement, the Site was referred to the EPA's Superfund program in November 1993.

Approximately 14,000 people live within a three-mile radius of the Site.
