Tennessee water quality overview

Tennessee's drinking water quality is good overall, with a state average score of 82.8 out of 100 — 8.6 points above the national average of 74.2. The median city score is 86, reflecting how water quality is distributed across the state's 299 ranked cities. 88% of Tennessee cities earned an A or B grade, indicating broadly strong water quality infrastructure. Only 2 cities received a failing grade. PFAS "forever chemicals" were detected in 80 of 299 cities (27%). Of those, 35 cities exceed the 2024 EPA maximum contaminant levels — a health concern requiring action. 227 cities have recorded health-based violations with the EPA — meaning contaminant levels exceeded safe limits or required testing was missed.
