Surface Water Results

The effects of the TVA ash spill on water quality are a mix of obvious and more subtle impacts. The physical impacts were immediate as ash from the failed impoundment completely filled two embayments and a portion of the Emory River main channel. Ash has also been carried downstream into the Clinch River and plumes have been observed entering the Tennessee River after heavy rainfall. The initial impacts of the slide killed or displaced fish and other aquatic life or caused physical impacts to fish through gillways, ingestation, etc.

Daily water quality testing has not indicated an impact to drinking water facilities. Rockwood and Kingston water is safe to drink. Water in close proximity to the spill site has contaminants at levels that would not be suitable for drinking water supply. However, there are no water treatment facilities in this immediate area.

The more subtle potential impacts to aquatic life in the spill area will need to be carefully tracked. For this reason, monitoring of area rivers and the collection of fish for tissue analysis began immediately following the event and will continue. Exceedences of Tennessee’s clean water goals have been noted. Parameters of concern that we are monitoring closely include arsenic, lead, thallium, and mercury. Fish tissue samples will be tracked for the metals associated with the ash.

Because clean water goals include criteria that measure both acute (short term) and chronic (longer term) toxicity, it may be some time before we can reach conclusions about the breadth of impacts to water quality in the Kingston area. In the meantime, we have committed to continued area monitoring and to make information available to the public as we fulfill our mandate the protect public health and water quality.
