Little Butte Water System is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 101 people from surface water.
As of August 1, 2026, its federal record holds 4 entries between 1991 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.
Of the 4, 2 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, the Surface Water Treatment Rules, and the Consumer Confidence Rule.
