Residents and commercial customers in the affected area are advised to boil all tap water used for drinking, cooking, making ice, brushing teeth or washing dishes as a precautionary measure. A one-minute rolling boil is sufficient. Cool the water before using. Alternatively, bottled water may be used. Any ice produced by automatic icemakers should be discarded.
For laundry, allow the water to run until clear before washing clothes.
Officials said the advisory may be lifted Tuesday, depending on testing results. However, the county will let residents know when the water is safe to resume normal usage.
