GRAND MOUND is one of 112 community water systems in Washington in the 3,301 to 10,000 people size category, serving 3,764 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 2009 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 4, 2 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 Consumer Confidence Rule, the Total Coliform Rules, and inorganic chemicals.
