Does Aqua Nj - Byram have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2026. The violations listed here began between April 2022 and January 2026. By type: 12 monitoring and reporting. The contaminant or rule involved most often is Gross alpha (excluding radon and uranium) (2 of them). EPA lists 6 as archived, 5 as resolved and 1 as unaddressed. 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.
