PLAIN FLATS WATER SYSTEM is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 29 people from groundwater.

As of August 1, 2026, its federal record holds 12 entries between 2004 and 2025, all of which EPA lists as closed.

Of the 12, 7 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, the Lead and Copper Rule, and the Consumer Confidence Rule.

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
