Drinking water in Mayhill, New Mexico is delivered through 4 EPA-regulated community water systems serving an estimated 1,855 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 37 violation records across the 4 active community systems shown here. Monitoring and reporting records are not present in the extract. The records carry 4 distinct EPA contaminant codes: Groundwater Rule, LEAD AND COPPER RULE REVISIONS, Revised Total Coliform Rule, Surface Water Treatment Rule.
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.

Figures here are the current EPA SDWIS extract joined to the 4 community water systems whose service area lists Mayhill, ranked against the 255 New Mexico 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.

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.
