RAINBOW WATER DISTRICT is one of 63 community water systems in Oregon in the 3,301 to 10,000 people size category, serving 6,300 people from surface water.

As of August 1, 2026, its federal record holds 16 entries between 1976 and 2025, all of which EPA lists as closed.

Of the 16, 15 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 Surface Water Treatment Rules, and inorganic chemicals.
