TREASURE ISLAND COUNTRY CLUB is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 321 people from groundwater.
As of August 1, 2026, its federal record holds 12 entries between 1979 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.
Of the 12, 5 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, synthetic organic chemicals, and the Radionuclides and Revised Rad Rule.
