VINEYARD ESTATES MWC is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 90 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 2002 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.
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.
