HAGERSTOWN, Md. (AP) - The U.S. Environmental Protection Agency says it wants to learn the extent of groundwater pollution from a Superfund site in Hagerstown.
The agency is asking the mayor and City Council on Tuesday to let it install detector devices in surface water at several city parks.
The EPA would then inject a non-toxic dye at the Central Chemical Superfund site and look for it the dye at the monitoring locations.
Central Chemical Corp. blended agricultural pesticides from the 1930s to the 1960s. The company dumped DDT, arsenic and other toxic chemicals in an old quarry on the property.
The EPA says groundwater contamination has been confirmed beyond the site's boundaries.
Central Chemical was added to the EPA's list of the nation's most hazardous waste sites in 1997.
