A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits.

System facts

System ID (PWSID): WA5392850
System type: Community Water System
Population served: 4,674
Service connections: 907
Ownership: local government
Water source: groundwater (wells)

WARDEN CITY OF is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, serving 4,674 people from groundwater.

As of August 1, 2026, its federal record holds 87 entries between 1979 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
