Pinal County, Arizona hosts 74 EPA-regulated community water systems delivering drinking water to approximately 420,676 people. Each system is catalogued in the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act, which mandates monitoring for dozens of regulated contaminants, public notification when standards are exceeded, and the issuance of an annual Consumer Confidence Report.
PlainEnviro's health-based SDWIS extract shows 779 violation records across these active community systems, with 35 systems carrying at least one record. The extract excludes monitoring and reporting violations. The county contains 17 incorporated places where these systems deliver service.
A historical health-based registry row does not establish water delivered today or describe current compliance. For current conditions, request the utility's most recent Consumer Confidence Report or contact the Arizona drinking water program. Figures shown here reflect only the health-based subset fetched from federal EPA SDWIS.

About This Data
Water system data comes from the EPA's Safe Drinking Water Information System (SDWIS). PlainEnviro's violation fetch is restricted upstream to records EPA flags as health-based and then joined to active community water systems. Monitoring and reporting violations are not included.
Figures here are the current EPA SDWIS extract joined to the 74 community water systems whose service area falls in Pinal County, ranked against the 15 Arizona counties with at least one system on file. Data current as of 2026-08-25. Editorial standards, methodology, report an error.
A health-based violation row in this extract is a historical EPA registry entry. It does not describe water delivered today or current compliance status. Many records are later resolved, and public water systems notify customers when required. For current conditions, contact your local water utility or the state drinking water program.
