HARSTINE ISLAND ESTATES ASSN is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 56 people from groundwater.

As of August 1, 2026, its federal record holds 26 entries between 1993 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

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 synthetic organic chemicals, the Total Coliform Rules, and inorganic chemicals.
