Does Fairmont Rv Resort have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in April 2026. The violations listed here began between September 2015 and April 2026. By type: 5 monitoring, 3 monitoring and reporting, 2 required treatment not met and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (8 of them). EPA lists 11 as resolved and 1 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.
