PALOMAR MOUNTAIN MUTUAL WATER CO. is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 193 people from groundwater.
As of August 1, 2026, its federal record holds 11 entries between 1980 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
Of the 11, 4 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 Miscellaneous Other Rules, the Radionuclides and Revised Rad Rule, and the Total Coliform Rules.
