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.
EPCOR adjusting water chemistry to mitigate lead
Starting in December 2022, EPCOR will add orthophosphate to its treated water to reduce lead. As EPCOR is Leduc’s water provider, this includes our community’s water supply. Orthophosphate is an odorless, tasteless substance that creates a protective barrier on plumbing surfaces to reduce the release of lead in drinking water from all sources, including lead service lines and plumbing. Many municipalities across North America use orthophosphate. It has no negative health effects, and is endorsed by Alberta Health Services and Alberta Environment and Parks.
B.C. community of Hedley under do-not-consume water advisory due to arsenic levels
Residents of a small B.C. community are facing an ongoing water issue that started in late December and could stretch into March. Located in the Southern Interior, the village of Hedley is under a do-not-consume water advisory because of higher-than-safe arsenic levels. The advisory came into effect on Christmas Day and, because of wrinkles caused by the ongoing coronavirus pandemic, is expected to last another four weeks.
