PALOUSE WATER DEPT CITY OF is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 1,298 people from groundwater.

As of August 1, 2026, its federal record holds 30 entries between 1979 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

The record involves volatile organic chemicals, the Total Coliform Rules, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
