Who owns and regulates St. Augustine Ws?

Does St. Augustine Ws have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2024. The violations listed here began between April 2016 and July 2024. By type: 6 monitoring and reporting, 3 monitoring, 2 public notice, recordkeeping or other and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 6 as archived, 3 as unaddressed and 3 as resolved. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
