Analysis

Wisconsin water quality overview

Wisconsin's drinking water quality is good overall, with a state average score of 78 out of 100 — 3.8 points above the national average of 74.2. The median city score is 82.1, reflecting how water quality is distributed across the state's 446 ranked cities. 78% of Wisconsin cities earned an A or B grade, indicating broadly strong water quality infrastructure. Only 19 cities received a failing grade. PFAS "forever chemicals" were detected in 64 of 446 cities (14%). Of those, 19 cities exceed the 2024 EPA maximum contaminant levels — a health concern requiring action. 4 cities have 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. 388 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.
