On June 3, 2016, surface water from the Woodland-Davis Clean Water Agency was introduced into the City of Davis water distribution system. Surface water from the Sacramento River is treated at the Regional Water Treatment Facility and then travels about 6 miles to Davis’ local distribution pipeline. As surface water is gradually introduced, weekly water quality samples are being taken at the following distribution sampling stations: 5th Street (downtown), Wake Forest Drive, Whaleback Park, Mockingbird Place, Wintun Place and Rockwell Drive.
Samples are taken at dedicated sampling stations located throughout the distribution system. These sites were chosen to reflect the overall water quality throughout Davis. All samples are tested for aluminum, calcium, iron, magnesium, manganese, total chromium, lead, zinc, color, turbidity, alkalinity, bicarbonate, carbonate, hydroxide, hardness, pH, orthophosphate as PO4, heterotropic plate count (measures bacteriological quality of drinking water) and asbestos. Distribution water quality sampling results for all parameters will be available monthly, for the 6 sampling stations, in the PDF files below. Sampling is currently planned to be conducted through August 2017.
The levels of orthophosphate at the sampling stations can serve as an indicator of whether surface water is reaching that area of town. If the orthophosphate level is above 0.5 mg/L then you are likely receiving a blend of surface and groundwater.
