HOLLISTER RANCH ESTATES is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 150 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 2003 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.
Of the 3, 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 inorganic chemicals.
