BUEHNER WATER SYSTEM - WEBER COMPLEX is one of 3,951 community water systems in California in the 500 or fewer people size category, formerly serving 30 people from groundwater.
EPA's federal records list this system as inactive in 2019; the record below is historical.
As of August 1, 2026, its federal record holds 5 entries between 1981 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.
Of the 5, 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 Miscellaneous Other Rules, the Total Coliform Rules, and the Radionuclides and Revised Rad Rule.
