Does Hidden Valley Amish School have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in February 2026. The violations listed here began between January 2024 and February 2026. 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 11 as archived 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.
