Analysis

Pennsylvania water quality overview

Pennsylvania's drinking water quality is below average overall, with a state average score of 58.3 out of 100 — 15.9 points below the national average of 74.2. The median city score is 57, reflecting how water quality is distributed across the state's 560 ranked cities. 48% of cities scored a D or F, pointing to significant water quality challenges across much of the state. 187 cities did earn an A or B grade, showing that strong systems do exist. PFAS "forever chemicals" were detected in 155 of 560 cities (28%). Of those, 81 cities exceed the 2024 EPA maximum contaminant levels — a health concern requiring action. 131 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. 487 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.
