Does Pinon Pines Mwc have drinking water violations?

Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in October 2024. The violations listed here began between January 2011 and October 2024. By type: 8 contaminant level above the legal limit, 2 monitoring and reporting, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Arsenic (5 of them). EPA lists 9 as resolved, 2 as addressed and 1 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement. 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.
