DESERT HILLS WATER is one of 84 community water systems in Arizona in the 3,301 to 10,000 people size category, serving 4,220 people from surface water.
As of August 1, 2026, its federal record holds 8 entries in 1988, all of which EPA lists as closed. Nothing has been added since 1988.
All 8 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.
