MEMPHIS, Tenn. — An investigation by the Tennessee Valley Authority shows that the public water supply in Memphis, Tennessee, is not affected by high levels of arsenic and other toxins found in monitoring wells at a coal-fired power plant.
However, results of the investigation released Wednesday also show a connection between the shallow aquifer where toxins were found and the deeper Memphis Sand Aquifer that provides the city’s drinking water.
TVA began investigating last spring after toxins ended up in wells that monitor pollution from coal ash ponds at its Allen Fossil Plant in Memphis. The shallow monitoring wells are near far deeper wells drilled directly into the Memphis Sand Aquifer. The TVA had planned to use the deeper wells to cool a nearby natural gas plant that will replace the coal plant.
