Public Health Sudbury & Districts has issued a drinking water advisory for all residents of Kagawong on Manitoulin Island.
According to the release, the advisory means people who take their water from the municipal system should not use it for drinking, consumption, or brushing their teeth, and boiling the water may not make it safe for drinking.
The Municipality of Kagawong says residents can bring and fill their own containers at the water treatment plant filling station.
Officials say residents should not use the water for consumption until advised otherwise by the agency.
