IMPERIAL ESTATES MHP 4 is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, formerly serving 30 people from groundwater.
EPA's federal records list this system as inactive in 1996; the record below is historical.
As of August 1, 2026, its federal record holds 16 entries between 1993 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.
All 16 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 volatile organic chemicals and the Total Coliform Rules.
