Water Quality/Consumer Confidence Reports (CCR):

Note:  As required by the California State Water Resources Control Board (SWRCB), the formal reports are updated annually and are due by July 1st of the next year.  For example, the upcoming 2025 report covers the most recent data available from 2025 and is due before July 1, 2026.  Please note that not all constituents have a SWRCB mandated testing period ranging from weekly to every 3+ years and the most recent test date is listed in the CCR.  Up to date water quality data is reported monthly to the SWRCB and available to the public (see SWRCB link below).

Questions about cloudy water

Customers may occasionally notice that the water coming from their taps appears opaque or cloudy. We want to assure customers that this is not a quality issue, and this water is perfectly safe to drink. Water looks like this when air mixes with water in the aquifer or pump column.
