A water quality advisory has been extended for the lower zone of the Okanagan Falls water system. Announced earlier this week, the Regional District for Okanagan Similkameen (RDOS) says the advisory for manganese will remain in place until further notice. The regional district says it “recognizes that residents in the lower zone are continuing to encounter poor water quality and the RDOS is working on making changes to the water system with the anticipation of long-term improvements to the water quality.”
