HILLSIDE MOBILE HOME PARK is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, formerly serving 15 people from groundwater.
EPA's federal records list this system as inactive in 2025; the record below is historical.
As of August 1, 2026, its federal record holds 19 entries between 1993 and 2000, all of which EPA lists as closed. Nothing has been added since 2000.
Of the 19, 18 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, the Consumer Confidence Rule, and the Lead and Copper Rule.
