TIETON WATER DEPT CITY OF is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 1,475 people from groundwater.

As of August 1, 2026, its federal record holds 62 entries between 1979 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

The record involves synthetic organic chemicals, volatile organic chemicals, and inorganic chemicals.
