Does Durant Utilities Authority have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in April 2024. The violations listed here began between October 2002 and April 2024. By type: 6 contaminant level above the legal limit, 5 monitoring and reporting and 1 required treatment not met. The contaminant or rule involved most often is Haloacetic acids (HAA5) (7 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. 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.
