LAKE CASSIDY ESTATES is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 70 people from groundwater.
As of August 1, 2026, its federal record holds 11 entries between 1992 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.
Of the 11, 9 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.
