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.

Water source: surface water (rivers, lakes, or reservoirs)

DANBURY WATER DEPARTMENT is among the 8 largest community water systems in Connecticut, serving 62,055 people from surface water.

As of August 1, 2026, its federal record holds 25 entries between 2009 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 25, 23 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 Surface Water Treatment Rules, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
