Superfund Site Profile
The 32-acre Centre County Kepone site, located in State College, Pennsylvania, was a chemical manufacturing facility. The facility produced the pesticide kepone in 1958, 1959 and 1963, and the pesticide mirex in 1973 and 1974. All chemical manufacturing operations at the facility ceased in March of 2004. Process wastes originally were disposed of on-site; in a spray irrigation field, a concrete lagoon, two other earthen lagoons, and also stored in drums on-site. After leaks were discovered, the material in the lagoons was solidified and disposed of in the two earthen lagoons and capped. It was later discovered however, the waste material had failed to solidify leading to hazardous materials leaching into the groundwater and surface water. Approximately 2,100 people live within a one-mile radius of the site. The closest residence is less than a quarter mile from the site. In 1982, a section of the adjacent Spring Creek was designated as a catch and release zone for fishing as a result of high levels of pesticides in fish. In 2001, the Commonwealth of Pennsylvania determined that the catch and release regulation was no longer required for contamination reasons.
