Does Aquarion Water Company (Dover) have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in September 2024. The violations listed here began between July 2006 and September 2024. By type: 6 monitoring and reporting, 3 contaminant level above the legal limit, 1 monitoring, 1 public notice, recordkeeping or other and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 6 as archived, 4 as resolved and 2 as addressed. 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. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
