CVWD must notify you by newspaper, mail, radio, TV, or hand-delivery if your water does not meet U.S. Environmental Protection Agency, State Water Resources Control Board, or California Department of Public Health standards, or if there is a waterborne disease emergency. The notice will describe any precautions you need to take, such as using store bought water or boiling your water. If a public notice is published and distributed regarding your drinking water, please carefully read it and follow the instructions.
