Kentucky Tap Water Quality by City

EPA UCMR5 PFAS monitoring, MCL / guideline flags, and WaterCheckup grades for 2 cities in Kentucky. "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).
