WALNUT GROVE MOBILE HOME PARK is one of 675 community water systems in Indiana in the 500 or fewer people size category, formerly serving 41 people from surface water.
EPA's federal records list this system as inactive in 2012; the record below is historical.
As of August 1, 2026, its federal record holds 3 entries between 1987 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.
Of the 3, 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 inorganic chemicals, volatile organic chemicals, and the Radionuclides and Revised Rad Rule.
