MARIAN HEIGHTS SUBDIVISION is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, serving 400 people from groundwater.
As of August 1, 2026, its federal record holds 6 entries between 1991 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.
Of the 6, 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 Consumer Confidence Rule, the Total Coliform Rules, and the Public Notice Rule and Revised PN Rule.
