HILDALE COLORADO CITY is one of 84 community water systems in Arizona in the 3,301 to 10,000 people size category, formerly serving 5,500 people from surface water.

EPA's federal records list this system as inactive in 2021; the record below is historical.

As of August 1, 2026, its federal record holds 28 entries between 1987 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 28, 27 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, synthetic organic chemicals, and the Total Coliform Rules.
