MONROE WATER SYSTEM is one of 111 community water systems in Washington in the 10,001 to 100,000 people size category, serving 23,467 people from surface water.
As of August 1, 2026, its federal record holds 14 entries between 1979 and 2024, all of which EPA lists as closed.
Of the 14, 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 inorganic chemicals, the Consumer Confidence Rule, and the Total Coliform Rules.
