Subject: [CPEO-MEF] Spring Valley (DC) perchlorate
 
Groundwater Toxin Found At Site Near Aqueduct
EPA, Army Corps Debate '03 Tests; Inaction Criticized

Random tests performed in summer 2003 found unsafe amounts of a chemical toxin a few hundred yards from Washington's drinking water supply, a discovery that has set off a tense, largely behind-the-scenes debate over what steps are necessary to protect the water and the public.

The high concentrations of perchlorate, a toxin typically found in chemical weapons and explosives, were detected by chance in June and September 2003 as part of a long-term study and cleanup of chemical contamination in the surrounding Spring Valley neighborhood. A researcher with the U.S. Environmental Protection Agency found the chemical in groundwater near the Washington Aqueduct reservoir at levels 80 times the amount EPA considers a risk to humans.

For the past year, the results were known only to a relatively small group of scientists, government officials and neighborhood activists. Officials at the aqueduct said there is no cause for alarm because significant amounts of perchlorate have not been detected in the drinking water. The aqueduct has conducted tests several times this year that can detect perchlorate at concentrations as low as 4 parts per billion.
