OAKLEY VALLEY WATER CORPORATION is one of 969 community water systems in Idaho in the 500 or fewer people size category, serving 500 people from groundwater.

As of August 1, 2026, its federal record holds 4 entries between 1991 and 2024, all of which EPA lists as closed.

Of the 4, 2 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 Groundwater Rule, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
