Boil water advisories in New Jersey
We do not read this state's advisories
We checked New Jersey DEP Water Supply's site on 22 August 2026 and did not find a list of active advisories published there. That is one page on one day, not a statement about what New Jersey DEP Water Supply publishes. Advisories may still be issued by your utility or your county directly.
