The water that we provide to your meter consistently meets or surpasses all Federal and State drinking water standards. However, for those who would like to have the water within their residence tested, CCWD provides as a courtesy to its customers this list of local State-certified commercial laboratories. As a public agency, we do not endorse the services of these laboratories.

You can also contact the State to request a local commercial laboratory by calling 916-323-3431 or emailing elapca@waterboards.ca.gov. The State also provides a map of current State-certified laboratories. We recommend that you confirm that any laboratory you choose to use is currently certified with the State prior to engaging its services.
