CHAPARRAL MOBILE RANCH is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 110 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1976 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.
All 3 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 the Radionuclides and Revised Rad Rule and the Total Coliform Rules.
