ILLAHEE OYEHUT is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 971 people from groundwater.

As of August 1, 2026, its federal record holds 14 entries between 1979 and 2000, all of which EPA lists as closed. Nothing has been added since 2000.

Of the 14, 11 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 and the Total Coliform Rules.
