TRENTON WATER WORKS is among the 11 largest community water systems in New Jersey, serving 217,000 people from surface water.

As of August 1, 2026, its federal record holds 8 entries between 1980 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 8, 5 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 the Stage 2 Disinfectants and Disinfection Byproducts Rule, synthetic organic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
