Study: Cancer risk 'disturbingly' higher near coal ash ponds
May 11th, 2009 by Jennifer Walker-Journey
Cancer rates among people living near coal ash ponds are “disturbingly high,” according to Environmental Integrity Project and Earthjustice, nonprofit organizations that studied Environmental Protection Agency (EPA) data from 210 coal ash ponds across the United States. The data is compiled in a report titled, “Coming Clean: What EPA Knows About the Dangers of Coal Ash.”
The EPA screening study conducted in 2002 was not made public until March 4, 2009. Numerous attempts to get the information made public through the Freedom of Information Act to the EPA during the Bush Administration were denied or released with the risk estimates blacked out. The data finally made public after seven years shows that cancer risk is substantially higher for up to one out of every 50 Americans living near wet ponds used to dispose of ash and scrubber sludge from coal-fired power plants across the United States.
The analysis focuses on 100 landfills and 110 surface impoundments examined by the EPA that lack effective synthetic liners to prevent leaks as the EPA found unlined and clay-lined waste units present far greater risks to both human health and ecosystems. These high-risk coal ash dump sites are in more than 35 states.
According to the report: “Can living next to one of these dumpsites increase your risk of getting cancer or other diseases? The U.S. Environmental Protection Agency (EPA) thinks so, especially if you live near one of those wet ash ponds, or surface impoundments, that dot the landscape near large coal plants, the pond has no protective liner, and you get your drinking water from a well … (N)earby residents have as much as a 1 in 50 chance of getting cancer from drinking water contaminated by arsenic, one of the most common, and most dangerous, pollutants from coal ash. And that’s not all. That same risk assessment says that living near ash ponds increases the risk of damage to the liver, kidney, lungs and other organs as a result of being exposed to toxic metals like cadmium, cobalt, lead, and other pollutants at concentrations far above levels that are considered safe. In addition, the danger to wildlife and ecosystems is simply off the charts, with one contaminant—boron—expected to leach into the environment at levels two thousand times thresholds generally considered to be safe.”
