LITTLE LAKE MOBILE HOME PARK is one of 3,951 community water systems in California in the 500 or fewer people size category, formerly serving 38 people from groundwater.
EPA's federal records list this system as inactive in 2026; the record below is historical.
As of August 1, 2026, its federal record holds 3 entries between 1980 and 1996, all of which EPA lists as closed. Nothing has been added since 1996.
All 3 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 Radionuclides and Revised Rad Rule and the Total Coliform Rules.
