MIDVALE FARMS WATER COMPA is one of 1,189 community water systems in Arizona in the 500 or fewer people size category, formerly serving 23 people from groundwater.

EPA's federal records list this system as inactive in 2004; the record below is historical.

As of August 1, 2026, its federal record holds 11 entries between 1986 and 1989, all of which EPA lists as closed. Nothing has been added since 1989.

All 11 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.
