MULINO WATER DISTRICT is one of 203 community water systems in Oregon in the 501 to 3,300 people size category, serving 700 people from groundwater.

As of August 1, 2026, its federal record holds 24 entries between 1976 and 2025, all of which EPA lists as closed.

The record involves the Lead and Copper Rule, the Total Coliform Rules, and the Consumer Confidence Rule.
