CUYAMACA WATER DISTRICT is one of 728 community water systems in California in the 501 to 3,300 people size category, serving 2,923 people from groundwater.
As of August 1, 2026, its federal record holds 11 entries between 1980 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.
Of the 11, 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 the Miscellaneous Other Rules, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
