The City of Gatineau issued a boil water advisory Wednesday for about 900 homes in the Hull sector. The advisory is in effect until further notice. It encompasses an area north of Boulevard des Hautes-Plaines between Boulevard de la Techologie and Boulevard de la Cité-des-Jeunes, south of Galene Street. Residents are advised to boil their tap water for at least one minute before consuming it. Once the advisory is lifted cold water taps must be opened and left running for one minute or it gets cold. Any ice made from tap water during the boil water advisory should be discarded.
