ALMA RANCHETTES is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 22 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 49 entries between 1989 and 2024, all of which EPA lists as closed.

Of the 49, 37 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 Total Coliform Rules, and volatile organic chemicals.
