MISSION HILLS CSD is one of 278 community water systems in California in the 3,301 to 10,000 people size category, serving 3,600 people from groundwater.
As of August 1, 2026, its federal record holds 2 entries in 2011, all of which EPA lists as closed. Nothing has been added since 2011.
All 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.
