Levels of lead in drinking water city-wide should begin dropping in early 2023 when orthophosphate is added at Edmonton’s water treatment plant, two years later than initially promised. Epcor announced Thursday the odourless, colourless chemical will be added to city water by early 2023. Orthophosphate creates a protective barrier inside a pipe to prevent lead from leaching into the water. Around 4,200 Edmonton homes are currently serviced by lead pipes owned by Epcor, the utility said. Adding this treatment by the end of 2020 was promised as part of broader lead-reducing plans approved by city council in March 2019 around the time Health Canada reduced the concentration of lead in water allowed to five micrograms per litre from 10 micrograms per litre.
Testing suggests 1 in 5 Winnipeg homes with lead pipes have unsafe levels of lead in drinking water
One in five Winnipeg homeowners with lead pipes will get unacceptable levels of lead in their drinking water the moment they turn on the tap, according to the City of Winnipeg. Under the city's lead water quality testing program, samples were taken from 268 homes with lead pipes between Aug. 15 and Nov. 19. The testing was done to ensure water quality met new national guidelines for lead in drinking water, which cut the acceptable amount of contamination in half last March. "Overall, the results are as expected," Renee Grosselle, manager of environmental standards with the City of Winnipeg, told reporters Tuesday afternoon.
