BETHEL ISLAND MHC is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 185 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1980 and 1984, all of which EPA lists as closed. Nothing has been added since 1984.
Of the 3, 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 Radionuclides and Revised Rad Rule and the Miscellaneous Other Rules.
