Drinking water in Mesilla, New Mexico is delivered through 1 EPA-regulated community water system serving an estimated 2,167 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 11 violation records across the 1 active community system shown here. Monitoring and reporting records are not present in the extract. The records carry 2 distinct EPA contaminant codes: Groundwater Rule, LEAD AND COPPER RULE REVISIONS.
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.
