superboj writes "Forget Deepwater Horizon or Three Mile Island: The biggest industrial disaster in American history actually happened in 2008, when more than a billion gallons of coal sludge ran through the small town of Kingston, Tennessee. This story details how, five years later, nothing has been done to stop it happening again, thanks to energy industry lobbying, federal inaction, and secrecy imposed on Congress. 'It estimated that 140,000 pounds of arsenic had spilled into the Emory River, as well as huge quantities of mercury, aluminum and selenium. In fact, the single spill in Kingston released more chromium, lead, manganese, and nickel into the environment than the entire U.S. power industry spilled in 2007. ... Kingston, though, is by far the worst coal ash disaster that the industry has ever seen: 5.4 million cubic yards of coal ash, containing at least 10 known toxins, were spilled. In fact, the event ... was even bigger than the Deepwater Horizon oil spill in April 2010, which spewed approximately 1 million cubic yards of oil into the Gulf of Mexico."
