The Tennessee Valley Authority has released results of an environmental investigation at the Allen Fossil Plant in Memphis. In teh report, the TVA says while arsenic and other “constituents” were found in the shallow upper aquifer, the public water supply in the deeper Memphis Aquifer is not affected.
The Southern Environmental Law Center responded to the report with the following statement:
“TVA’s statement about the remedial investigation confirms our biggest fear–that there is a hydraulic connection between the arsenic-contaminated groundwater and the Memphis Sand Aquifer, the city’s drinking water source,” said Amanda Garcia, staff attorney with the Southern Environmental Law Center. “Although TVA is working on a contingency plan to supply cooling water from Memphis Light, Gas & Water, we still have major concerns that the pressure from pumping millions of gallons of water each day from a nearby station could pose similar contamination risks. These threats to Memphis’s drinking water source could have been avoided if TVA had gone through the appropriate steps including conducting an in-depth environmental review, involving the public in the decision-making process and admitting its on-site contamination sooner. TVA should learn from its past mistakes and involve the public now in deciding how to provide water for the gas plant, including fully analyzing options like using recycled gray water as it originally proposed to the citizens of Memphis.”
