MAHER MUTUAL WATER COMPANY is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 140 people from groundwater.
As of August 1, 2026, its federal record holds 12 entries between 1980 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 12, 5 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 inorganic chemicals, the Miscellaneous Other Rules, and the Radionuclides and Revised Rad Rule.
