KINO RANCH 1 is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 150 people from groundwater.
EPA's federal records list this system as inactive in 2008; the record below is historical.
As of August 1, 2026, its federal record holds 19 entries between 1987 and 1990, all of which EPA lists as closed. Nothing has been added since 1990.
All 19 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 volatile organic chemicals and inorganic chemicals.
