RANCHO ESTATES MUTUAL WATER CO. is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 200 people from groundwater.
As of August 1, 2026, its federal record holds 19 entries between 1982 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 19, 14 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, inorganic chemicals, and the Lead and Copper Rule.
