AVOCA WATERWORKS is one of 333 community water systems in Wisconsin in the 501 to 3,300 people size category, serving 545 people from groundwater.

As of August 1, 2026, its federal record holds 21 entries between 1992 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.

All 21 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 and the Total Coliform Rules.
