NORTH HIGH ROCK ESTATES W.S. is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 68 people from groundwater.
As of August 1, 2026, its federal record holds 26 entries between 2003 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.
Of the 26, 23 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, the Total Coliform Rules, and inorganic chemicals.
