SANDFLAT WATER ASSOCIATION is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 260 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries between 1999 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.
All 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 inorganic chemicals, the Total Coliform Rules, and the Lead and Copper Rule.
