The water CCWD provides to your meter consistently meets or surpasses all federal and state drinking water standards. However, for customers interested in having the water within their residence tested, here is a map of current State-certified laboratories. Customers can also contact the State to request a local commercial laboratory by calling 916-323-3431 or emailing elapca@waterboards.ca.gov. CCWD recommends confirming that any laboratory you choose to use is currently certified with the State prior to engaging its services.
