Drinking water in El Mirage, Arizona is delivered through 20 EPA-regulated community water systems serving an estimated 335,830 people. Each system is tracked in the EPA Safe Drinking Water Information System (SDWIS) under the Safe Drinking Water Act, which requires testing for regulated contaminants, consumer notification of violations, and publication of an annual Consumer Confidence Report.

PlainEnviro's health-based SDWIS extract shows 216 violation records across the 20 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 7 distinct EPA contaminant codes: Chlorite, Lead and Copper Rule, Interim Enhanced Surface Water Treatment Rule, Surface Water Treatment Rule, Arsenic and 2 others. 4 TRI-reporting industrial facilities are also located within the city limits.

A past EPA health-based registry row does not describe water delivered today or current compliance status; utilities notify customers and remediate under state primacy oversight when required. For current water-quality status and treatment practices, review your local utility's most recent Consumer Confidence Report or contact the Arizona drinking water program. All records above reflect federal EPA SDWIS data and are not independently verified against state databases.

About This Data

Figures here are the current EPA SDWIS extract joined to the 20 community water systems whose service area lists El Mirage, ranked against the 191 Arizona places with at least one system on file. Data current as of 2026-08-25.

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.

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.

TRI facility data comes from the EPA Toxic Release Inventory. Facilities shown are those that self-report to the TRI program. PlainEnviro presents this data without advocacy framing.
