olean well field

LAUREN ST

The 1.5 square-mile Olean Well Field Superfund Site is comprised of three public and 50 private wells which are contaminated with trichloroethylene (TCE). Much of the groundwater contamination is believed to be the result of industrial operations at several nearby commercial establishments. Contamination of the areas was discovered in 1981. The public wells were constructed in the 1970s to alleviate the need for a surface water treatment plant, which draws water from Olean Creek. However, use of the wells was discontinued after Olean city officials detected TCE in the groundwater. In 1990, the public wells were reactivated after two air strippers were constructed to treat the groundwater. Site-related contaminants have migrated from shallow groundwater to deeper levels. The groundwater located in the upper level flows toward and discharges into the Allegheny River. Approximately 18,200 people live in the City of Olean. Site Responsibility: This site is being addressed through Federal and potentially responsible party actions.
