Does Calamity Water Users Assn have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in June 2024. The violations listed here began between July 2004 and June 2024. By type: 4 monitoring, 2 public notice, recordkeeping or other, 2 required treatment not met, 2 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 7 as resolved, 3 as archived and 2 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
