MARANA MUNICIPAL - MARANA is one of 67 community water systems in Arizona in the 10,001 to 100,000 people size category, serving 15,162 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries between 1979 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.
All 5 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, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Radionuclides and Revised Rad Rule.
