KITTITAS COUNTY WATER DISTRICT #4 is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 510 people from groundwater.

As of August 1, 2026, its federal record holds 6 entries between 1993 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 6, 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 the Stage 2 Disinfectants and Disinfection Byproducts Rule, the Total Coliform Rules, and the Consumer Confidence Rule.
