CHILOQUIN MUNICIPAL WATER DEPT is one of 203 community water systems in Oregon in the 501 to 3,300 people size category, serving 730 people from groundwater.

As of August 1, 2026, its federal record holds 37 entries between 1976 and 2025, of which 6 remain open; none are health-based.

Of the 37, 25 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 Consumer Confidence Rule, and the Radionuclides and Revised Rad Rule.
