New Jersey has 637 active non-transient non-community water systems, 18% of the state's 3,496 active systems.

Does Mt Olive High 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 September 2025. The violations listed here began between May 2011 and September 2025. By type: 7 monitoring and reporting, 2 reporting, 2 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 6 as resolved, 4 as archived and 2 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.
