HOLMES HARBOR WATER CO is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 110 people from groundwater.

As of August 1, 2026, its federal record holds 25 entries between 1979 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 25, 22 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 inorganic chemicals, the Total Coliform Rules, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
