MOUNTAIN DELL WATER INC is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, serving 250 people from groundwater.

As of August 1, 2026, its federal record holds 10 entries between 1986 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 10, 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 inorganic chemicals, the Consumer Confidence Rule, and the Radionuclides and Revised Rad Rule.
