Does City of Dunseith have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in July 2025. The violations listed here began between September 1991 and July 2025. By type: 5 monitoring and reporting, 4 public notice, recordkeeping or other, 1 required treatment not met, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Public Notice (4 of them). EPA lists 6 as resolved, 4 as archived and 2 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.
