NOGALES CITY OF is one of 67 community water systems in Arizona in the 10,001 to 100,000 people size category, serving 22,000 people from groundwater.
As of August 1, 2026, its federal record holds 313 entries between 1980 and 2025, all of which EPA lists as closed.
Of the 313, 301 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 synthetic organic chemicals, inorganic chemicals, and volatile organic chemicals.
