Arizona
According to EPA SDWIS, Yuma, Arizona is served by 20 community water systems covering about 167,652 people. The same extract lists 266 health-based violation records, most recently coded 4006 in 2025. Counts are historical EPA registry rows, not a current compliance or drinkability score.
Drinking water in Yuma, Arizona is delivered through 20 EPA-regulated community water systems serving an estimated 167,652 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 266 violation records across the 20 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 11 distinct EPA contaminant codes: Combined Uranium, Groundwater Rule, LEAD AND COPPER RULE REVISIONS, Arsenic, Revised Total Coliform Rule and 6 others. 10 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 Yuma, 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.
