Does Aldridge Ditch Co Ws 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 January 2021 and March 2026. By type: 7 public notice, recordkeeping or other, 3 monitoring and reporting, 1 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Consumer Confidence Rule (6 of them). EPA lists 6 as unaddressed, 5 as resolved and 1 as archived. 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. 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.
