COUGAR RIDGE is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 216 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 1998 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
Of the 4, 1 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.
