Superfund Site Profile
The Olean Well Field is located in Olean, New York. The 1.5-square-mile area includes three public and 50 private wells contaminated with volatile organic compounds (VOCs) such as trichloroethylene (TCE). Much of the groundwater contamination is believed to be the result of industrial operations at several nearby commercial establishments. Contamination was discovered in 1981. Use of the public wells was discontinued after detection of the TCE and an old surface water filtration plant was reactivated to provide water to city residents. In 1990, the public wells were reactivated after two air strippers were installed to treat the groundwater. Following immediate actions to protect human health and the environment, site investigations and long-term cleanup efforts are ongoing.
