SINGLE TREE ESTATES is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 146 people from groundwater.
As of August 1, 2026, its federal record holds 25 entries between 1979 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
All 25 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 volatile organic chemicals, inorganic chemicals, and the Lead and Copper Rule.
