Does Msad 33 Wisdom Jr-Sr High School have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in December 2023. The violations listed here began between January 2006 and December 2023. By type: 9 monitoring and reporting, 2 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Lead and Copper Rule (5 of them). EPA lists 9 as resolved, 2 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
