Does Acoma Main have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in November 2025. The violations listed here began between October 2019 and November 2025. By type: 10 monitoring and reporting, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Gross alpha (excluding radon and uranium) (4 of them). EPA lists 8 as resolved and 4 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
