The Regional District of Central Okanagan has upgraded a previous water quality advisory to a boil water notice for the Killiney Beach and Westshore Estates water systems.

Each system off of Westside Road serves more than 250 properties.

鈥淗igher turbidity in the water system sources has resulted in a poor rating,鈥� said Bruce Smith, communications officer.

鈥淭he health risk posed to particularly at risk populations such as newborns, the elderly and people with weakened

immune systems increases as turbidity levels rise. Turbidity can interfere with disinfection, limiting chlorine鈥檚 ability to remove or inactivate viruses, bacteria and parasites.鈥�

All Killiney Beach and Westshore Estates water customers should drink boiled water or a safe alternative.

Water intended for drinking, washing produce, making beverages or ice, or brushing teeth should be boiled for at least one minute.
