CITY OF FULLERTON is one of 92 community water systems in California in the more than 100,000 people size category, serving 139,461 people from surface water.
As of August 1, 2026, its federal record holds 4 entries between 1992 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.
Of the 4, 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 Total Coliform Rules and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
