Does Willowcreek Store & Cafe have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in March 2026. The violations listed here began between July 2024 and March 2026. By type: 7 monitoring, 2 public notice, recordkeeping or other, 2 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (7 of them). EPA lists 9 as resolved, 2 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
