Does Aspc Yuma have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in February 2026. The violations listed here began between July 2021 and February 2026. By type: 6 reporting, 3 monitoring and reporting, 1 monitoring, 1 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 11 as resolved 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.
