OREGON WATERWORKS is one of 87 community water systems in Wisconsin in the 10,001 to 100,000 people size category, serving 11,200 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, 1 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.
