Tennessee Valley Authority shares 2018 CCR groundwater monitoring and corrective action report
The Tennessee Valley Authority (TVA) recently shared its 2018 coal combustion residual (CCR) groundwater monitoring and corrective action reports online.
The public web page also includes fact sheets and information specific to TVA’s CCR units. The reports show elevated levels of molybdenum, arsenic, fluoride, lead, cobalt, lithium or cadmium above groundwater protection standards at some of TVA’s CCR sites.
“Public drinking water supplies are not impacted,” TVA said in a press release. “The data reflects the quality of groundwater beneath TVA’s CCR units. It does not mean there are adverse impacts to human health or the environment.”
The Environmental Protection Agency’s (EPA) 2015 CCR Rule establishes a process, implemented over time, for monitoring, investigating and addressing any issues through corrective action. It requires groundwater monitoring of active, inactive and new CCR impoundments as well as active and new CCR landfills through multiple phases of groundwater monitoring including baseline sampling, detection monitoring, and assessment monitoring.
