System facts

System ID (PWSID): NJ1408001
System type: Community Water System
Population served: 15,881
Service connections: 5,000
Ownership: local government
Water source: groundwater (wells)

DENVILLE TWP WATER DEPT is one of 154 community water systems in New Jersey in the 10,001 to 100,000 people size category, serving 15,881 people from groundwater.

As of August 1, 2026, its federal record holds 76 entries between 1993 and 2025, all of which EPA lists as closed.

Of the 76, 75 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
