Analysis

Illinois water quality overview

Illinois's drinking water quality is good overall, with a state average score of 79.7 out of 100 — 5.5 points above the national average of 74.2. The median city score is 83.4, reflecting how water quality is distributed across the state's 891 ranked cities. 83% of Illinois cities earned an A or B grade, indicating broadly strong water quality infrastructure. Only 24 cities received a failing grade. PFAS "forever chemicals" were detected in 178 of 891 cities (20%). Of those, 25 cities exceed the 2024 EPA maximum contaminant levels — a health concern requiring action. 24 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. 695 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.
