Just weeks after recent headlines about hexavalent chromium, a cancer-causing toxic chemical, contaminated drinking water systems around the U.S., a new report shows that scores of leaking coal ash sites across the country are additional documented sites for such contamination.
Hexavalent chromium first made headlines after Erin Brockovich sued Pacific Gas & Electric because of poisoned drinking water from hexavalent chromium. Now new information indicates that the chemical leaks readily from leaking coal ash dump sites maintained for coal-fired power plants.
Public interest law firm Earthjustice, Physicians for Social Responsibility, Environmental Integrity Project and the Sierra Club are pushing for federally-enforceable safeguards from coal ash as this new information is released. Also, in a signal that the Senate Environment and Public Works Committee recognizes the hazards of hexavalent chromium exposure, they have called on U.S. Environmental Protection Agency Administrator Lisa Jackson to testify tomorrow on a hearing about the chemical.
“Communities near coal ash sites must add hexavalent chromium to the list of toxic chemicals that threaten their health and families,” said Lisa Evans, senior administrative counsel at Earthjustice. “It is now abundantly clear that EPA must control coal ash disposal to prevent the poisoning of our drinking water with hexavalent chromium.”
Coal ash, the leftover waste from power plants, contains arsenic, lead, cadmium, mercury, selenium and many other chemicals that can cause cancer and damage the nervous system and organs, especially in children. Hexavalent chromium is a highly toxic carcinogen when inhaled, and recent studies from the National Toxicology Program indicate that when leaked into drinking water, it can also cause cancer.
“The cancer risk from hexavalent chromium is one more serious threat to health from coal ash,” said Barbara Gottlieb, Deputy Director for Environment & Health at Physicians for Social Responsibility. “To protect the public from carcinogens and other dangerous substances, the EPA needs to regulate coal ash as a hazardous waste.”
“The pollution from coal ash sites is making people sick,” said Dalal Aboulhosn who works on coal ash for the Sierra Club. “As we’ve seen time and again, big polluters can’t be trusted to police themselves. We need EPA to hold them accountable.”
“Studies by EPA, the state of California, and the Agency for Toxic Substances Disease Registry show that ingesting minute amounts of hexavalent chromium increases the risk of cancer,” said Eric Schaeffer, executive director for Environmental Integrity Project.
“Coal ash dumps have contaminated groundwater with much higher concentrations of this deadly carcinogen, according to the industry’s own monitoring data. The Obama Administration should keep its promise to respect science and protect the public’s health, by putting strict standards in place to keep this contamination from spreading even further.”
Among the findings from the new report:
• The U.S. Environmental Protection Agency found that the type of chromium that leaches from coal ash sites is nearly always of the hexavalent variety, which is the most toxic form of chromium.
• The threat of hexavalent chromium drinking water contamination is present at hundreds of unlined coal ash sites across the country.
• At least 28 coal ash sites in 17 states have already released chromium to groundwater at levels exceeding by thousands of times a proposed drinking water goal for hexavalent chromium.
• Power plants dump more than 10 million pounds of chromium and chromium compounds into mostly unlined or inadequately lined coal ash landfills, ponds and fill sites each year. The electric power industry is the largest single source of chromium and chromium compounds released to the environment.
• The U.S. Department of Energy and electric utility industry have known for years about the aggressive leaking of hexavalent chromium from coal ash.
• Hexavalent chromium contamination from coal ash is clearly a grave threat. Yet the U.S. EPA, which is currently in the process of deciding whether or not to regulate coal ash as a hazardous waste, has completely ignored the cancer risk from chromium in groundwater.
