Who owns and regulates Withrow Water Works?

Does Withrow Water Works have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in April 2024. The violations listed here began between October 1979 and April 2024. By type: 9 monitoring and reporting, 1 monitoring, 1 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (3 of them). EPA lists 6 as resolved and 6 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.
