FRIESLAND WATERWORKS is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, serving 345 people from groundwater.

As of August 1, 2026, its federal record holds 27 entries between 1987 and 2026, all of which EPA lists as closed.

Of the 27, 25 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 synthetic organic chemicals, the Total Coliform Rules, and the Groundwater Rule.
