Changes

Aside from the TVA disaster, the EPA has documented the following damage cases in TN:

 [[U.S. Department of Energy]] – Oak Ridge Y-12 Plant Chestnut Ridge Operable Unit 2, Oak Ridge: Aluminum, arsenic, iron, and selenium contamination, as well as fish deformities and fish kills from coal ash releases.

 [[Tennessee Valley Authority]] – [[Bull Run Fossil Plant]], Oak Ridge: Exceedancess of aluminum, calcium, iron, and sulfate were detected

in surface water and a toxicity study indicated the potential for ecological impacts. In addition, Earthjustice, Environmental Integrity and Sierra Club identified five additional sites where coal ash has been responsible for environmental contamination in Tennessee.

 [[Tennessee Valley Authority]] – [[John Sevier Fossil Plant]]. On-site groundwater contamination including exceedances of cadmium, aluminum, manganese, sulfate, and arsenic.

 Trans-Ash CCW Landfill, Ash from TVA– Johnsonville Fossil Plant. Off-site damage to groundwater and private residential water wells with mercury. Tenn. Dept. of Environment and Conservation had to connect a residence to the municipal water supply because the water had become un-potable.

 [[Tennessee Valley Authority]] – [[Cumberland Steam Plant]]. On-site groundwater, which may spread into nearby drinking water sources, contains arsenic more than twice the MCL, selenium 3 times the MCL, and boron 13 times the Child Health Advisory level.

 [[Tennessee Valley Authority]] – [[Gallatin Fossil Plant]]. An unlined ash pond contaminated groundwater with beryllium up to 6 times the MCL, cadmium, nickel exceeding the TN MCL by 2.5 times and boron over the Child Health Advisory. Concentrations of aluminum, iron, manganese, sulfate and TDS exceed SMCLs.

 [[Tennessee Valley Authority]] – [[Johnsonville Fossil Plant]]. An active ash disposal area resides on an unlined island in the middle of the Tennessee River. Groundwater on the island and at-on shore dumps contains arsenic, aluminum, boron, cadmium, chromium, iron, lead, manganese, molybdenum, sulfate and TDS far above federal MCLs, SMCLs, and federal health advisory levels. Disposal areas discharge into recreational waters of Tennessee River within a mile of New Johnsonville and Camden municipal water intake pipes.<ref>[http://earthjustice.org/sites/default/files/library/references/tn-coal-ash-factsheet-1111.pdf "Tennessee Coal Ash Factsheet"] Earthjustice, accessed January 19, 2011.</ref>
