Does Lyndsay'S Tavern 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 August 2023 and October 2025. By type: 8 monitoring and 4 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (8 of them). EPA lists 10 as archived, 1 as unaddressed and 1 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
