TOPPENISH WATER DEPARTMENT is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, serving 8,950 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 1979 and 2025, all of which EPA lists as closed.
All 4 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
