Tennessee  Source Water Assessments

This website contains Source Water Assessment summaries for public water systems in the State of Tennessee. These reports present susceptibility analysis findings and the susceptibility score for each public water system. The susceptibility analysis score indicates the potential risk (Low, Medium, High) of the water systems to contamination. The susceptibility analyses are required for each water system in order for Tennessee's Wellhead Protection/Source Water Assessment program to be effective and meet congressional requirements of the 1996 amendments to the Safe Drinking Water Act.
