British Columbia's Ministry of Health is warning residents in Metro Vancouver and the Fraser Valley of possible water contamination connected to the recent flooding in the province. Record-setting precipitation fell between Nov. 14 and Dec. 2 in southwestern B.C., causing severe flooding that destroyed homes and farms, and caused landslides that killed several people. Officials say heavy rain may have caused overflow or failure of liquid manure storage systems in the region. The province says it is working with farm operators to reduce the risks of possible overflow.
