Superfund Site Profile
The Chisman Creek site, located in York County, Virginia is a 27-acre site consisting of four former sand and gravel pits in which an estimated over 500,000 tons of fly ash from the Yorktown Power Generating Station was disposed from 1957 to 1974. The fly ash was removed from one of the pits and placed in another pit in the 1970s. In the early 1980s, the Virginia State Board of Health, the Virginia State Water Control Board, and the Virginia Institute of Marine Science sampled residential wells and the surface water in the area of the pits in response to a homeowner reporting discolored well water. These investigations found heavy metal contamination in Chisman Creek and in the groundwater in and near the fly ash disposal areas. This site was proposed to the National Priorities List on December 30, 1982 and formally added to the list on September 8, 1983.
