LAKE GROVE WATER DISTRICT is one of 203 community water systems in Oregon in the 501 to 3,300 people size category, serving 3,100 people from surface water.
As of August 1, 2026, its federal record holds 30 entries between 1991 and 2024, all of which EPA lists as closed.
Of the 30, 26 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, the Total Coliform Rules, and the Consumer Confidence Rule.
