A boil water advisory has been issued for the village of Alma, about 79 kilometres south of Moncton, because of high levels of turbidity in the reservoir. "These levels exceed the New Brunswick maximum acceptable concentrations," a notice issued by the local government on Wednesday morning says. Recent heavy rainfall caused the problem, according to chief administrative officer Hanna Downey — a drastic change from last weekend when the village almost ran out of water and had to urge residents to conserve as much as possible.
