What you haven't been told about chemicals polluting the aquifer that serves Del., Md., N.J.
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.
Those assurances have proved false.

Hundreds of Thousands Exposed Daily to Rad Levels Many Times over Safety Limits
Radioactivity levels in state drinking water wells are much higher than previously known and at-risk wells cover a bigger slice of the Garden State, according to agency documents released today by Public Employees for Environmental Responsibility (PEER). Despite significant adverse public health implications of the findings, the state has not taken steps to alert or protect affected populations.

A February 2009 DWQI report estimated that more than 211,000 people are exposed to an individual cancer risk which is 600 times the acceptable risk level. DWQI recommended that the state adopt a drinking water MCL for radon 222 but it was not acted upon and no follow-up action is scheduled.
