Tennessee Coal Sludge Disaster What Happened? The largest environmental disaster in U.S. history occurred on December 22nd, 2008 when a 84-acre pit containing toxic coal combustion residue at the Tennessee Valley Authority Fossil Plant in Kingston, Tennessee gave way. According to a report by AECOM, the firm hired to perform the root cause report, a â€Å"combination of the high water content of the wet ash, the increasing height of ash, the construction of the sloping dikes over the wet ash, and the existence of an unusual bottom layer of ash and silt were among the long-evolving conditions that caused the ash spill at Kingston Fossil Plant† (TVA, 2010). The resulting slide sent a wave of over a billion gallons of sludge out on the†¦show more content†¦On top of emitting 1.9 billion tons of carbon dioxide each year, coal-fired power plants in the United States also create 120 million tons of toxic waste. That means each of the nations 500 coal-fired power plants produces an average 240,000 tons of toxic waste each year. A power plant that operates for 40 years will leave behind 9.6 million tons of toxic waste† (2009). Coal Combustion Residue despite containing toxic metals such as arsenic, mercury, lead, selenium, and cadmium that are proven to cause cancer, kidney problems, birth defects, and wreck havoc on the nervous system. Coal Combustion Residue can is disposed by either being land filled, used to reclaim mine shafts, or are stored in pits on-site of coal burning plants. Even without a spill these contaminants can leach into the ground and pose a health risk if they are not disposed of properly. What was dangerous about this spill? The Tennessee Coal Valley plant in a press release detailing the extent of the disaster showed the sheer magnitude of this spill, â€Å"In just one year, the plant’s byproducts included 45,000 pounds of arsenic, 49,000 pounds of lead, 1.4 million pounds of barium, 91,000 pounds of chromium and 140,000 pounds of manganese.
