RAVENSDALE WATER SUPPLY is one of 3,227 community water systems in Washington in the 500 or fewer people size category, serving 389 people from surface water.

As of August 1, 2026, its federal record holds 23 entries between 1979 and 2025, all of which EPA lists as closed.

Of the 23, 22 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, inorganic chemicals, and the Consumer Confidence Rule.
