Analysis

Ohio water quality overview

Ohio's drinking water quality is good overall, with a state average score of 77.3 out of 100 — 3.1 points above the national average of 74.2. The median city score is 80.6, reflecting how water quality is distributed across the state's 511 ranked cities. 82% of Ohio 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 152 of 511 cities (30%). Of those, 44 cities exceed the 2024 EPA maximum contaminant levels — a health concern requiring action. 2 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. 398 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.
