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. New Jersey has 637 active non-transient non-community water systems, 18% of the state's 3,496 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,313 New Jersey systems (95%) list groundwater as their primary source.

Who owns and regulates Union Township Elem School?

EPA lists Union Township Elem School as owned by a local government. The NJ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 51 of the 293 active systems in Hunterdon County (17%) are also owned by a local government.

Does Union Township Elem School have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2024. The violations listed here began between July 2019 and January 2024. By type: 11 monitoring and reporting and 1 required treatment not met. The contaminant or rule involved most often is Lead and Copper Rule (12 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.
