CORNER BROOK, N.L. -- The mayor of Corner Brook, N.L., says a boil water advisory will likely remain in effect until early next week after a chlorine leak at the city's water treatment plant.
Charles Pender says all home and businesses are affected in the city of about 20,000 people and in the nearby town of Massey Drive.
Pender says the leak appears to have been caused by a valve connected to a pressure gauge in the new automated plant, which has only been in use for about five months.
He says a chemical spill team from the fire department in Grand Falls-Windsor was called in and has given the all clear after it was determined that no chlorine gas had escaped into the environment.
Pender says with low chlorine levels in the water supply the city has switched to its old reservoir system as backup and water availability won't be affected.
He says under provincial regulations tests must show three consecutive days where chlorine levels have returned to normal before the boil water advisory can be lifted.
