LAMONTAI IMPROVEMENT WTR DIST is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 255 people from groundwater.
As of August 1, 2026, its federal record holds 28 entries between 1976 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 28, 21 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 Groundwater Rule.
