COSMOPOLIS WATER DEPARTMENT is one of 428 community water systems in Washington in the 501 to 3,300 people size category, serving 1,812 people from surface water.

As of August 1, 2026, its federal record holds 46 entries between 1979 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.

Of the 46, 39 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, inorganic chemicals, and the Consumer Confidence Rule.
