Analysis

Vermont water quality overview

Vermont's drinking water quality is good overall, with a state average score of 76.7 out of 100 — 2.2 points above the national average of 74.5. The median city score is 82.4, reflecting how water quality is distributed across the state's 90 ranked cities. 72% of Vermont cities earned an A or B grade, indicating broadly strong water quality infrastructure. Only 5 cities received a failing grade. PFAS "forever chemicals" were detected in 3 of 90 cities (3%). Of those, 1 city exceeds the 2024 EPA maximum contaminant levels — a health concern requiring action. 1 city has lead levels exceeding the EPA action level of 15 ppb, typically a sign of aging lead service lines or lead solder in older plumbing. Residents in these areas should use an NSF 53-certified filter. 82 cities have recorded health-based violations with the EPA — meaning contaminant levels exceeded safe limits or required testing was missed. Use the table below to find your city's specific record.
