From Pittsburgh Post-Gazette:

Two southwestern Pennsylvania fly ashdisposal sites are among 28 such sites in 17 states that have contaminated groundwater by leaking toxic, cancer-causing hexavalent chromium, according to a new report by Earthjustice and two other environmental groups.

Unsafe hexavalent chromium levels were found in groundwater near a landfill used by Allegheny Energy’s 1,710-megawatt Hatfield’s Ferry power plant in Greene County; and around an unlined pond and landfill near the GenOn’s Seward power plant in New Florence, Indiana County, the report found.

Another Pennsylvania fly ash disposal site, an unlined pond used by PPL’s Martins Creek power plant in Northhampton County, in the eastern end of the state, was also on the report’s list.

Hexavalent chromium was made famous by the 2000 film “Erin Brockovich.”

The report released Tuesday calls for tighter drinking water limits for chromium and federal regulations designating coal fly ash as a hazardous waste. The report was released on the eve of scheduled Senate testimony by U.S. Environmental Protection Agency Administrator Lisa Jackson about the public health concerns of contaminated drinking water and hexavalent chromium exposure.

“It is now abundantly clear that EPA must control coal ash disposal to prevent the poisoning of our drinking water with hexavalent chromium,” said Linda Evans, Earthjustice senior administrative counsel.

Studies by the EPA, the state of California and the agency for Toxic Substances and Disease Registry have found that exposure in drinking water to small amounts of hexavalent chromium can increase human cancer risk.
