PHILADELPHIA (March 8, 2010) -- The U.S. Environmental Protection Agency announced the addition of the Dwyer Property Ground Water Plume located north of Elkton, Md. to the Superfund National Priorities List.

The National Priorities List is a national list of sites where hazardous contaminants could impact public health and/or the environment. National Priorities 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.

The site, which is currently abandoned and heavily overgrown, is on the list 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 property 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 Dwyer site is one of 10 sites nationwide that EPA is adding to the National Priorities List today.
