MAPLE GROVE MHP is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, serving 125 people from groundwater.
As of August 1, 2026, its federal record holds 17 entries in 1994, all of which EPA lists as closed. Nothing has been added since 1994.
All 17 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.
