Does Roman Nose State Park have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2025. The violations listed here began between October 2021 and October 2025. By type: 8 monitoring, 2 monitoring and reporting, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (8 of them). EPA lists 10 as resolved and 2 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.
