A little over a week ago more than one billion gallons of wet coal ash spilled after a retaining wall ruptured forty miles west of Knoxville. Initially authorities didn't realize how much of eastern Tennessee was actually covered in the semi-toxic sludge. More than one billion gallons of coal ash have spilled through the valley adjacent to the Kingston Fossil Plant and now Tennessee Valley authorities have to figure out how to get rid of it and clean up the state. Josh Flory from the Knoxville News Sentinel just returned from the spill site. He joins John and Adaora from Knoxville.
