Water clarity is one factor that affects the quality of drinking water. Water that is cloudy often contains extremely fine particles like organic matter and sediment that can come from run-off from heavy rainfall during the fall and winter months. To ensure the safety of the water, Metro Vancouver conducts daily tests and takes precautions in anticipation of events that can cause cloudiness, also known as high turbidity levels.

Metro is committed to delivering and maintaining the best drinking water possible. To ensure drinking water meets provincial regulations and federal guidelines, Metro Vancouver has developed a Drinking Water Treatment Program that includes primary and secondary disinfection.

While treated drinking water is essential to human health, some marine and aquatic organisms can be affected by the chorine in our drinking water. Metro has developed strict guidelines and procedures for people to use when releasing tap water into the local environment to help prevent these types of problems.
