ARIZONA WATER CO - SUPERIOR is one of 84 community water systems in Arizona in the 3,301 to 10,000 people size category, serving 4,393 people from groundwater.
As of August 1, 2026, its federal record holds 32 entries between 1978 and 1991, all of which EPA lists as closed. Nothing has been added since 1991.
All 32 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, inorganic chemicals, and synthetic organic chemicals.
