NEW YORK — The U.S. Environmental Protection Agency (EPA) has finalized a plan to clean up ground water at the Peninsula Boulevard Ground Water Plume Superfund site in Hempstead, N.Y.
The ground water is contaminated with tetrachloroethylene and trichloroethylene, dry-cleaning chemicals that can seriously impact people’s health, EPA says.
The cleanup plan entails extracting ground water from the site using pumping wells and treating the water to remove the contaminants before it is disposed of at a public wastewater treatment facility or sent back into surface or ground water.
Residents in the area get their drinking water from the Long Island American Water Co., which operates a drinking water well field approximately 1,000 feet north of the Peninsula Boulevard site. EPA did not detect any contaminants above acceptable levels in ground water from the company during its investigation.
A series of New York State Department of Environmental Conservation investigations in the 1990s revealed an extensive ground water contaminant plume at the site of the former Grove Cleaners, EPA says.
The site was added to the Superfund list of the most contaminated hazardous waste sites in 2004, and EPA investigated the site from 2005 to 2010.
