Environmental Investigations

Note: Environmental investigations are currently being conducted at the site. Conclusions about the presence or absence of risk at a CCR unit cannot be made based on the individual data results posted on this website. The collective data will be reported and evaluated in the Environmental Assessment Report (EAR). This will be used by TVA and TDEC to determine if further study is necessary. Conclusions about actions to be taken at the site will then be addressed in a Corrective Action/Risk Assessment (CARA) plan, after being made available for public review and comment.
