Sometimes a situation occurs where the safeness (due to biological or chemical contamination) or the availability of water is a concern for the proper operation of a food service facility. When the water supply may have been biologically contaminated a Boil Water Advisory will be issued. If it is confirmed that the water supply has been biologically contaminated a Boil Water Notice will be issued.
If a boil water advisory is issued for your area, it means that the water supply in your area may be contaminated, either by a sewage overflow, a water line break, a chemical spill, a natural disaster such as a hurricane or flood, or some other unusual event. Please check with your local government for the status of boil water advisories in your area.
If a issue a boil water notice, it means the water in your area is definitely contaminated. Your family members could get very sick if they drink the water or use it to cook food.
