RIO VISTA MOBILE HOME PARK is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, serving 217 people from groundwater.
As of August 1, 2026, its federal record holds 18 entries between 1987 and 1988, all of which EPA lists as closed. Nothing has been added since 1988.
All 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 volatile organic chemicals and the Radionuclides and Revised Rad Rule.
