What does “non-transient non-community water system” mean?

A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Connecticut has 483 active non-transient non-community water systems, 20% of the state's 2,363 active systems. 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 The Masters School?

EPA lists The Masters School as privately owned. The CT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 179 of the 219 active systems in Hartford County (82%) are also privately owned.

Does The Masters School have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2022. The violations listed here began between January 2014 and April 2022. By type: 9 monitoring and reporting, 2 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (2 of them). EPA lists 11 as resolved and 1 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.
