Does Watchung Hills Hs-Field have drinking water violations?
EPA's records list 8 violations for this system; 2 are health-based, and the most recent began in May 2025. The violations listed here began between April 1996 and May 2025.

The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 5 as resolved, 2 as unaddressed 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.
