OKU INCORPORATED is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 35 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries in 2019, all of which EPA lists as closed. Nothing has been added since 2019.
All 3 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 volatile organic chemicals.
