Every utility EPA sampled for PFAS under UCMR 5, any other community system serving 3,300 people or more, and any smaller one with results from 2020 on, from CDC. Other systems appear in ZIP code results. People served is what each utility reports to EPA. Data: EPA SDWIS 2026 Q3, UCMR 5 and EPA’s 2012 to 2019 compliance results, and CDC’s yearly averages.
