An environmental group said the Tennessee Valley Authority (TVA) has, again, delayed the release of tests results from its wells drilled into Memphis’ drinking water source but a TVA official said they don’t have the results and are awaiting them to compile into a state report.
TVA drilled five wells into the Memphis Sand Aquifer last year. The agency planned to draw 3.5 million gallons of water from the aquifer to cool its new $975 million natural gas plant, which will replace an older coal-burning plant.
That plan was halted last year after a local group, Protect Our Aquifer, filed a lawsuit to stop TVA from using the wells. Then, TVA announced its researchers had found high levels of arsenic and lead in groundwater under a coal ash pit close to the wells drilled into the aquifer.

After that, TVA said it would not use the wells until an investigation proved they were safe to use. The agency hired the United States Geological Survey (USGS) and the University of Memphis (U of M) to conduct parts of the investigation.
In early October, TVA ran the wells for a 24-hour period to test the water from them for any contaminants.
Amanda Garcia, an attorney with the Southern Environmental Law Center, said TVA promised at the time to release the results at the end of the month. They didn’t, she said. The agency, then, delayed the release of the results until January, she said.
Through a state records requests, Garcia found a document that says TVA won’t release the results until March.
“We are concerned that the public — and especially regulators — are not being made aware of the results of this test that is suppose to provide insights on whether the cooling water wells at the gas plant are safe to operate,” Garcia said.
But Scott Brooks, a TVA spokesman, said, simply, they don’t have the results.
“(The Tennessee Department of Environment and Conservation) has asked that we put all the results together at once, including U of M and USGS,” Brooks said. “We’re still awaiting the final results.”
“It would be hard to push back a “timeline” by 5 months when the initial discovery of the arsenic was barely 6 months ago. We just contracted with USGS and U of M in August.”
But the SELC’s Garcia said TVA has known “for several years” that there was arsenic in the groundwater under the coal ash ponds at the Allen Fossil Plant. Though, TVA found extremely high levels of arsenic in a groundwater well in fall 2016, she said.
“At least our understanding is that they did not provide that information to (TDEC) until May of 2017,” Garcia said. “The public didn’t know about it until July of 2017. Meanwhile, they were planning to operate gas plant wells, which could potentially pull contaminated groundwater into the city’s drinking water source.”
Ward Archer, president of Protect Our Aquifer, said the fact that the results of the tests have no yet been made public was “concerning.”
“If the test isn’t complete or something else is going on, just tell us,” Archer said. “Tell us something. To just be completely silent about it seems odd to me. It doesn’t instill trust, which I think we could use some of, I think.”
When asked to clarify whether or not TVA had the test results, Brooks said, "U of M and USGS still have their tests, from what I understand, and we are still compiling ours. TDEC has asked for it all to be presented at once.”
SELC’s Garcia said her group has requested the test results from TVA through a Freedom of Information Act (FOIA) request and “TVA denied expedited treatment of the request despite the potential risk to the city’s only drinking water source.”
“That TDEC allegedly asked for TVA to present all of the information at once wouldn’t prevent TVA from informing the residents of Memphis who rely on the Memphis Sand Aquifer for drinking water sooner rather than later,” Garcia said.
