AJO DWID is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, serving 405 people from groundwater.
As of August 1, 2026, its federal record holds 2 entries between 1984 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.
All 2 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 and the Radionuclides and Revised Rad Rule.
