Field notes
Tapcensus says its database covers 142,155 active public water systems serving 346.1 million people, with EPA data updated Oct. 7, 2026. A lookup is matched to a county, not guaranteed to identify the utility serving one address; the homepage says the largest community system is usually the city or town utility. Results distinguish routine monitoring or reporting violations from open health-based violations and link to EPA facility reports.
