westinghouse electric corp. (sharon plant)

469 SHARPSVILLE AVE

The former Westinghouse Electric Sharon Transformer Plant ("The Westinghouse Sharon Site") is a 58-acre facility located in Mercer County, Pennsylvania. During its operation from 1922 to 1985, Westinghouse manufactured electrical transformers at the site. Between 1936 and 1976, Westinghouse used blends of polychlorinated biphenyls (PCBs) and trichlorobenzene in the manufacturing of some of the transformers. During the operation of the plant, spills resulted in the contamination of soils, groundwater, and the sediments of the nearby Shenango River. At least 6,000 gallons of solvents and oil leaked from an underground tank in 1984. In 1985, EPA detected PCBs at two of the four points where the plant discharged wastewater to the Shenango River. The Pennsylvania Department of Environmental Resources (PADER) detected PCBs in river sediments between the Site and a water intake for the Aqua America Water Company which provides drinking water to approximately 75,000 people. The water intake is 1,600 feet downstream from the plant's (former) discharge points. In 1998, Westinghouse Electric Corporation was acquired by CBS Corporation. CBS was subsequently acquired by Viacom Inc. which reverted back to CBS Corporation in January 2006. Only a small portion of the property is still owned by CBS. The remaining portions are owned by other commercial enterprises including AK Steel Corporation and Winner Development LLC.
