SHIRONA WATER SYSTEM is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 243 people from groundwater.

As of August 1, 2026, its federal record holds 24 entries between 1979 and 2025, all of which EPA lists as closed.

Of the 24, 16 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 the Total Coliform Rules, inorganic chemicals, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
