ISLAND ESTATES is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, serving 50 people from groundwater.
As of August 1, 2026, its federal record holds 16 entries between 1994 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 16, 15 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 Consumer Confidence Rule.
