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.

*** Disclaimer ***

EPA Guidance for state Source Water Assessment Programs has the ranking scheme of high, moderate and low for potential contamination to the water source.  This is a relative index of potential contamination to the untreated water source.  To ensure safe drinking water, all public water systems treat and routinely test their water. 

Each state has developed its own ranking system such that comparison from one state to another is not reasonable.  A number of states have actually chosen to score individual potential contaminant sources rather than the water sources.  There is also not a reasonable correlation for a “high” for a surface water source with a “high” for a ground water source.  For the purposes of Tennessee’s Consumer Confidence Reports, this relative index of risk of potential contamination has been adapted to more appropriately read “reasonably susceptible” for “high”; “moderately susceptible” for “moderate”; and “slightly susceptible” for “low.”
