COPPER MOUNTAIN RANCH CFD is one of 272 community water systems in Arizona in the 501 to 3,300 people size category, serving 1,071 people from groundwater.
As of August 1, 2026, its federal record holds 11 entries between 1980 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.
Of the 11, 9 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
