MCMINNVILLE WATER & LIGHT is among the 23 largest community water systems in Oregon, serving 34,515 people from surface water.
As of August 1, 2026, its federal record holds 36 entries between 1976 and 2024, all of which EPA lists as closed.
All 36 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, inorganic chemicals, and the Total Coliform Rules.
