Who owns and regulates Dexter By the Sea?

Does Dexter By the Sea have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in July 2015. The violations listed here began between October 1999 and July 2015. By type: 6 public notice, recordkeeping or other, 4 contaminant level above the legal limit and 2 monitoring and reporting. The contaminant or rule involved most often is Consumer Confidence Rule (6 of them). EPA lists 8 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.
