PROGRESSIVE FLAT WATER ASSN is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 335 people from groundwater.

As of August 1, 2026, its federal record holds 60 entries between 1979 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

Of the 60, 56 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 synthetic organic chemicals, volatile organic chemicals, and inorganic chemicals.
