EPA Prioritizes Texas Site to List of Contaminated Areas
The Environmental Protection Agency (EPA) proposed to add the El Dorado Chemical Company site in near San Antonio, to the National Priorities List (NPL) of Superfund sites, a list of sites that pose risks to public health and the environment. Superfund is the federal program that investigates and cleans up the most complex, uncontrolled or abandoned hazardous waste sites in the country and converts them into productive community resources by eliminating or reducing public health risks and environmental contamination.
The site is located in the suburb of Live Oak, Bexar County, northwest of San Antonio. The former cleaning product manufacturing site contains soil and groundwater contaminated with chlorinated solvents including tetrachloroethene, trichloroethene, dichloroethene and vinyl chloride.
“Every year we identify sites that are serious risks to public health and the environment,” said EPA regional administrator Ron Curry. “Cleaning hazardous waste in our communities and returning properties to environmental and economic vitality will improve quality of life for the affected communities.”
If not addressed, the contaminants could harm the Edwards Aquifer, which provides drinking water to 215,722 local residents. Tetrachloroethylene is considered a potential human carcinogen. Animal studies have shown exposure over long periods could cause other effects in the liver and kidneys and changes in brain chemistry.
EPA regularly works to identify companies or people responsible for the contamination at a site, and requires them to conduct or pay for the cleanup. For the newly listed sites without viable potentially responsible parties, EPA will investigate the extent of the contamination before assessing how best to treat it.
The NPL contains the nation’s most serious uncontrolled or abandoned hazardous waste sites. The list serves as the basis for prioritizing both enforcement actions and long-term EPA Superfund cleanup funding; only sites on the NPL are eligible for such funding. A site’s listing neither imposes a financial obligation on EPA nor assigns liability to any party.
