WASHINGTON STATE UNIVERSITY is one of 111 community water systems in Washington in the 10,001 to 100,000 people size category, serving 21,506 people from groundwater.
As of August 1, 2026, its federal record holds 7 entries between 1979 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.
All 7 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 synthetic organic chemicals, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
