Water Quality Consumer Confidence Report
State law requires water retailers to provide information to their customers about the quality of their drinking water and the reliability of the water supply. The City of Chino Hills is dedicated to providing you with a safe and reliable supply of high-quality drinking water. Prior to reaching your faucet, your water undergoes an extensive treatment and testing process as dictated by the State Water Resources Control Board (SWRCB) and the U.S. Environmental Protection Agency (USEPA).
To learn more about Chino Hills' water quality, we urge you to read the annual Water Quality Consumer Confidence Report. Any questions referencing this report, can be made to our Water Quality Technician at 909-364-2808. You can also download The Water Quality Consumer Confidence Report (PDF).
