Good evening – earlier this evening, during routine water quality testing, a City water well located at Gilman Road and Camino Arroyo tested for nitrate levels at 12 milligrams per liter which exceeded the maximum contaminant level (MCL) of 10 milligrams per liter.
City staff immediately reported this occurrence to the California State Water Resources Board (Board). The Board is requiring that the City notify all residents and customers of the nitrate levels and provide important information concerning the drinking water.
The cause of the nitrate level is not known at this time and the well is no longer providing any water to consumers. The well will be continually tested until it meets the MCL of 10 milligrams per liter and is approved for use by the Board.
Please read the Drinking Water Warning below as it will provide all the health and safety information pertinent to this situation.
