PHILADELPHIA (October 19, 2010) -- The U.S. Environmental Protection Agency announced today that it is proposing the addition of the Dwyer Property Ground Water Plume located north of Elkton, Md. to the Superfund National Priorities List.

The site, which is currently abandoned and heavily overgrown, is being proposed to the NPL because the groundwater is contaminated with levels of trichloroethene (TCE) that are above EPA’s Safe Drinking Water Act maximum contaminant levels for potable water.

The site is a portion of a former industrial facility, Triumph Explosives, Inc., which primarily manufactured explosives for the Department of Defense from the 1930s through the end of World War II.

The National Priorities List is a national list of sites where hazardous contaminants could impact public health and/or the environment. National Priority List sites undergo a thorough investigation to determine the full nature and extent of contamination. EPA or the parties responsible for the contamination then address whatever risks the sites pose to human health and the environment.

Once a site has been proposed for inclusion to the National Priority List, there is a 60-day comment period. A final decision on listing sites will be made after EPA has evaluated and responded to all the public comments in writing. Nationwide, EPA is proposing to add nine sites to the Superfund list.
