GERMANTOWN WATER UTILITY is one of 87 community water systems in Wisconsin in the 10,001 to 100,000 people size category, serving 20,027 people from groundwater.
As of August 1, 2026, its federal record holds 10 entries between 1988 and 2024, all of which EPA lists as closed.
Of the 10, 8 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 2 Disinfectants and Disinfection Byproducts Rule, and the Lead and Copper Rule.
