TVA’s Coal Ash Sludge Pond Bursts
Dec 22nd, 2008 by admin
Update (Thanks Dave Cooper): This Tennessee TVA spill is over 40-48 times bigger than the Exxon Valdez spill in Alaska, if local news accounts are correct. This is a huge environmental disaster of epic proportions; approximately 1 Billion gallons of nasty black coal ash flowed into tributaries of the Tennessee River - the water supply for Chattanooga TN and millions of people living downstream in Alabama, Tennessee and Kentucky. We’re “lucky” it was sludgy and slow moving, or thousands could have died. Click here to see an amazing aerial video of the spill - the big chunks in the river are mounds of coal ash.

Suprisingly, the industry still says that coal will be “clean” if we find out how to sequester the carbon– here is more terrible proof they are wrong. On Monday, 39 groups, including our friends with the Citizens Coal Council and The Alliance for Appalachia banded together to ask President-Elect Obama to overturn Bush’s recent attempts to de-regulate coal ash even more.
In some twist of grim irony, the night before these groups sent out their demand for increased regulation of coal ash, 4 to 6 feet of toxic coal ash and ice cold slurry burst out of a faulty TVA containment pond in Eastern Tennessee and destroyed 12 homes, 400 acres, and wrecked a train; you can read more about it in the Knoxville News Sentinel. This break isn’t the first terrible sludge dam disaster. It is a huge tragedy, and we won’t know for years how the mercury, arsenic, and other toxic heavy metals like beryllium and cadmium commonly found in coal ash will have impacted the local community and wildlife.
Coal ash is what is leftover when you burn coal. Coal ash is an enormous problem throughout the US. It is more radioactive than nuclear waste, according to Scientific American and is under-regulated. It is made into concrete, drywall, and as a road building material. People living near coal ash dumps have been estimated to have up to 900 times the national cancer rates.
I might hazard a guess that that cancer figure just increased even more in eastern Tennessee.
