SW1/4 SEC21 WATER CO-OP is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 30 people from surface water.

EPA's federal records list this system as inactive in 2002; the record below is historical.

As of August 1, 2026, its federal record holds 2 entries between 1985 and 1986, all of which EPA lists as closed. Nothing has been added since 1986.

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 inorganic chemicals and the Radionuclides and Revised Rad Rule.
