Does The Richford Diner have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2025. The violations listed here began between January 2003 and October 2025. By type: 6 monitoring and 6 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 8 as resolved and 4 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.
