Does Riverside Inn Glendive have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2025. The violations listed here began between October 2022 and July 2025. By type: 11 monitoring and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (11 of them). EPA lists 8 as archived and 4 as resolved. 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.
