Toxic Coal Ash Spill
News 2 Comments »A six-foot wall of coal fly ash mud broke loose from an earthen dam early Monday morning near Harriman, TN, washing out a road, isolating a dozen homes and posing a possible threat to drinking water downstream from Watts Bar dam on the Tennessee River. No injuries were reported, TVA officials said.
The spill involved 2.6 million cubic yards of dry material, or an estimated 525 million gallons of wet coal fly ash sludge. The material flowed from facilities at the 1.7 gigawatt Kingston Steam Plant into the Emery River, then into the lake at Watt’s Bar dam on the Tennessee River. The earthen dam that broke was one of three being maintained by the TVA as part of the Kingston facility. The other two dams are intact at present.
As of Tuesday, TVA and municipal water authorities had not closed down drinking water intakes on the river. Tom Kilgore, president and CEO of the Tennessee Valley Authority, told the Nashville Tennessean newspaper that heavy metal contamination was a concern, but the situation was “probably safe.”
The spill is the largest on record, and compares to a 300 million gallon coal slurry sludge spill on Oct. 11, 2000 at Inez, Martin County, Kentucky.
