TUMWATER CITY OF is one of 111 community water systems in Washington in the 10,001 to 100,000 people size category, serving 51,802 people from groundwater.

As of August 1, 2026, its federal record holds 10 entries between 1979 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 10, 6 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 the Total Coliform Rules, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
