Pennsylvania Tap Water Quality by City

EPA UCMR5 PFAS monitoring, MCL / guideline flags, and WaterCheckup grades for 2 cities in Pennsylvania. "At Risk" means at least one UCMR analyte flagged above an EPA limit or a regulated PFAS violation on record for that system. "Monitor" means no such flag in UCMR data, but the city profile is medium or high concern. "Safe" means no exceedance flags and a low-concern city profile (still not a guarantee for every tap).

Average water hardness in Pennsylvania: 37 ppm → Mean of UCMR5 values for 2 tracked Pennsylvania cities (not every utility).

ABOUT WATER QUALITY IN PENNSYLVANIA

Pennsylvania water quality varies by city and water system. UCMR5 reports PFAS and related analytes; the "above limit" column uses the EPA-limit flags bundled with each analyte in our dataset (same basis as city pages). Here, 2 of 2 tracked cities show at least one such flag or a regulated violation count.
