CORNER BROOK, NL — There were two boil water advisories in Canada this week because of issues at water treatment plants in Cornerbrook, NL, and Saskatoon.

A boil water advisory was issued for all homes and businesses in Corner Brook after a chlorine leak at the city’s water treatment plant. There’s no word on what caused the leak.

And residents of a Saskatchewan city are being told to boil their tap water as a precaution because it might be contaminated.

Dustin MacDonald, the city’s acting communications manager, said partially treated water spilled into treated water at one of North Battleford’s treatment plants on Aug. 11. That happened for six minutes before alarms went off and the plant was shut down.

“The partially treated water went through the filter system as well as the ultraviolet disinfection system … the accepted engineering travel time would indicate that the partially treated water was caught within the water treatment plant, but that needs to be scientifically proven that this water did not reach the water distribution system.”

Engineers and city staff were doing tests and analyzing data to determine how far the water got, said MacDonald.

The city said operational error was the cause.

About 8,000 litres of water goes through the system in six minutes – enough to fill about eight hot tubs, MacDonald said.
