Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,263 Connecticut systems (96%) list groundwater as their primary source.

Who owns and regulates Mountain Dairy Creamery?

Does Mountain Dairy Creamery have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2025. The violations listed here began between October 2017 and December 2025. By type: 6 monitoring, 4 public notice, recordkeeping or other and 2 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 9 as resolved, 2 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
