The Coast Guard and Florida Marine Patrol try to mark sunken debris in channels, but they can't mark or locate all the floating debris in the open waters of the rivers, bays and gulf. Until you're informed that tap water from your water system is safe and free of dangerous bacteria, drink water that was bottled before the hurricane. Water saved in clean containers is good for two to three weeks. In addition to drinking, use safe water for cooking, washing dishes and brushing teeth. To kill bacteria in tap water that has possibly been contaminated, use eight drops of chlorine bleach per gallon and let the bleached water stand for 10 minutes before drinking.
Some stores sell iodine tablets that kill bacteria.
If you have fuel to spare, boiling water for at least three minutes kills bacteria. If you have natural gas appliances, check your home for the smell of gas before turning on any switches or appliances. If you smell gas call, Okaloosa Gas. Don't turn anything on. Most gas stoves and water heaters will work without electricity, but some with electronic pilot lights require electric power to start on their own.
