Residents in Meaford have officially been given the all-clear to use their water again after a “do-not-consume” advisory was issued on Sunday. City officials declared the “do-not-consume” advisory over Wednesday night after receiving confirmation from the Grey Bruce medical officer of health, Dr. Ian Arra, that the water from the municipal water system was safe to drink. While the advisory has been lifted, the municipality says the state of emergency remains in place. The municipality issued the emergency Sunday following concerns about contaminants leaching into the ground and the water supply in Georgian Bay around Johnny B’s Automotive and Car Care following the fire.
Testing the waters: Do Regina's asbestos-cement water mains pose a risk?
Snaking beneath Regina's streets are 600 kilometres of water mains built with asbestos-cement. That's about 60 per cent of some 1,000 kilometres of the mains that deliver water to homes around the city.

Windsor delays adding fluoride back to drinking water by one year
According to the report presented to WUC, the additional testing is primarily necessary to determine how fluoride will interact with the phosphoric acid already present in the system as a mechanism to prevent lead from leaching into the water supply. "WUC will be the first known water utility to add fluoride to the drinking supply which already contains phosphoric acid for purposes of lead mitigation," reads an excerpt from the report. "While other utilities have both additives … no other utility (in North American based on research to date) is known to have fluoride added subsequent to the addition of phosphoric acid."
