ARLINGTON CITY WATER SUPPLY is one of 203 community water systems in Oregon in the 501 to 3,300 people size category, serving 628 people from groundwater.
As of August 1, 2026, its federal record holds 13 entries between 1976 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 13, 11 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 Radionuclides and Revised Rad Rule, and the Consumer Confidence Rule.
