HIGHLAND ESTATES is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 110 people from groundwater.
As of August 1, 2026, its federal record holds 11 entries between 1979 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.
Of the 11, 10 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 inorganic chemicals, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
