The Sharon Steel Corporation (Farrell Works Disposal Area) site is located in Farrell, Mercer County, Pennsylvania. Located within a few hundred feet of the Ohio border and bordered on the east by the Shenango River, the site covers about 325 acres, including 100 acres of wetlands. Waste disposed at the site included byproducts from steel manufacturing including contaminated sludge, slag, and pickle liquor. Disposal activities resulted in contamination of soil, sediment and groundwater with hazardous chemicals. EPA placed the site on the National Priorities List (Superfund list) in 1998. The site is being cleaned up through federal, state and potentially responsible party (PRP) actions.
