DEEP WELL COOP is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 17 people from groundwater.
EPA's federal records list this system as inactive in 2025; the record below is historical.
As of August 1, 2026, its federal record holds 3 entries between 1989 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.
Of the 3, 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 Consumer Confidence Rule, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Radionuclides and Revised Rad Rule.
