Does Williston WTP have drinking water violations?
EPA's records list 11 violations for this system; 2 are health-based, and the most recent began in July 2023. The violations listed here began between September 1991 and July 2023. By type: 7 monitoring and reporting, 2 contaminant level above the legal limit, 1 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Haloacetic acids (HAA5) (3 of them). EPA lists 7 as resolved and 4 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.
