Do not drink the water without boiling it first. Bring all water to a rolling boil for at least two minutes, and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, food preparation, and water for pets. Boiling kills harmful bacteria and other organisms in the water that may cause illness. You should throw away ice made during the time the notice was issued (freezing does not kill bacteria).
