EAST TROY ALONG WEST BANK OF MIAMI RIVER

The East Troy Contaminated Aquifer site is located in the eastern portion of the City of Troy, Miami County, Ohio along the western bank of the Great Miami River. The site boundaries and all contamination source(s) have not yet been identified. The remedial investigation and feasibility study (RI/FS) will provide this information. Existing data demonstrates that the site includes at least a 25-block area where volatile organic compounds (VOCs) have been identified in groundwater, soils, and indoor air space of residential, public and commercial properties. Across the Great Miami River, within 0.25 miles of the site is the city of Troy's East Well Field which serves as a drinking water supply for the city of Troy. Since 1988, the VOCs, cis-1, 2-dichloroethane (cis-1, 2-DCE) and trichloroethene (TCE), have been consistently detected in samples taken from the East Well Field. The site was proposed on the National Prorities List (NPL) in September 2007, and one year later in September 2008, the site was finalized on the NPL.
