July 25, 2010 - Tainted groundwater is spreading across thousands of acres in northern Delaware and has reached the Potomac Aquifer, which supplies drinking water to people across much of Delaware, Maryland and New Jersey.
In some areas of the upper Potomac near Delaware City and New Castle, concentrations of benzene, vinyl chloride and chlorinated benzenes are so high that exposure poses an immediate health threat. Elevated levels of these industrial byproducts significantly increase the risks of cancer. Sustained exposure could kill.
Northern Delaware is home to some of the worst chemical dumping grounds in America, a legacy of broken promises and corporate misdeeds. Regulators working for Delaware and the U.S. Environmental Protection Agency have long claimed that the deep clay layers above the aquifer protected it from the foul waters discharged by chemical and petroleum manufacturers.
