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

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.

Does Timberlane Middle School have drinking water violations?

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.
