HAZEL GREEN WATERWORKS is one of 333 community water systems in Wisconsin in the 501 to 3,300 people size category, serving 1,193 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1991 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.
Of the 3, 2 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 Total Coliform Rules.
