The City of Montreal says a boil-water advisory in Montreal's West Island has now been fully lifted, more than a week after tests found water in the Dollard-des-Ormeaux reservoir had been contaminated.

As of Friday, residents in DDO could safely use their taps, but people in Pierrefonds-Roxboro had to wait until Sunday evening, when the city sent out a notice saying their water was once again safe to consume.

In a statement to CBC, city spokeswoman Audrey Gauthier said construction work was being done to seal and reinforce the reservoir last week. She says the renovations combined with heavy rains allowed contaminants to seep through a crack in the structure — one that wasn't visible to workers.

Gauthier says the city found the crack and filled it, secured the rest of the reservoir and disinfected the water inside it. She says in the past week, the water quality has been tested more than it usually is in a whole month, with samples being taken almost every hour.

Gauthier says the city needed to have two full days of lab results in both areas demonstrating the water was safe to drink again before the advisory could be lifted.
