Does Mbnf-Mirror Lake Pg have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2022. The violations listed here began between April 1995 and July 2022. By type: 10 monitoring and reporting, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 6 as resolved and 6 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.
