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 Marshall Hill Elem School?
EPA lists Marshall Hill 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. 36 of the 149 active systems in Passaic County (24%) are also owned by a local government.
Does Marshall Hill Elem School have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in September 2025. The violations listed here began between September 2000 and September 2025. By type: 6 monitoring and reporting, 2 reporting, 2 required treatment not met and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Lead and Copper Rule (5 of them). EPA lists 8 as unaddressed, 3 as resolved and 1 as archived. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
