Does Pomerene Dwid have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in November 2025. The violations listed here began between July 2024 and November 2025. By type: 4 monitoring and reporting, 3 public notice, recordkeeping or other, 3 contaminant level above the legal limit, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Fluoride (4 of them). EPA lists 9 as resolved and 3 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.
