Interior Health and Regional District of North Okanagan - Greater Vernon Water (RDNO-GVW) remind customers on provincial recommendation that newborns (0-6 mos) and people with weakened immune systems drink boiled water or a safe alternative at all times if served by an unfiltered surface water source.


Good: If the reading for your source is “Good” except for the note above there is no requirement to take extra precautions at this time.
