Circle Court Ground Water Plume Added to NPL of Superfund Sites

Site makes National Priorities List after tests showed that public water supply and five private wells within a one-mile radius all had elevated TCE levels

EPA Texas Circle Court Ground Water Plume NPL

The U.S. Environmental Protection Agency (EPA) announced that, with support from the Texas Commission on Environmental Quality, the Circle Court Ground Water Plume in Willow Park, Texas, has been added to the National Priorities List (NPL) of Superfund sites.

The site is located in Willow Park, Parker County. In 2006, routine sampling of a well in the city’s water system showed concentrations of trichloroethene (TCE) to be above safe levels. Subsequent tests showed that public water supply and five private wells all had elevated TCE levels. These water sources are all within a one-mile radius of the site, which extends for a half-mile along Russell Road. The city of Willow Park shut down the wells and installed a carbon filter to provide safe drinking water for affected residents. The source of the contamination has not been identified.

Superfund is the federal program that investigates and cleans up the most complex, uncontrolled or abandoned hazardous waste sites in the country.

The NPL is the list of hazardous sites in the United States eligible for longterm cleanup action financed under the federal Superfund program. EPA works to identify companies or people responsible for the contamination at a site and requires them to conduct or pay for the cleanup. For newly listed sites without viable potentially responsible parties, EPA will investigate the full extent of the contamination before starting significant cleanup at the site. It may take several years before cleanup funding is available for these sites.
