Drinking water in Nunapitchuk, Alaska is delivered through 1 EPA-regulated community water system serving an estimated 496 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 13 violation records across the 1 active community system shown here. Monitoring and reporting records are not present in the extract. The records carry 3 distinct EPA contaminant codes: Groundwater Rule, Total Haloacetic Acids (HAA5), TTHM.
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.

All records above reflect federal EPA SDWIS data and are not independently verified against state databases.
