MESQUITE MUTUAL WATER CO. is one of 3,951 community water systems in California in the 500 or fewer people size category, formerly serving 42 people from groundwater.

EPA's federal records list this system as inactive in 2025; the record below is historical.

As of August 1, 2026, its federal record holds 11 entries between 2002 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.

Of the 11, 9 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 the Consumer Confidence Rule.
