If you live in an area under a boil advisory or you have lost water pressure at your tap or if the water pressure is extremely low State Health Officer Jimmy Guidry, MD, recommends that you disinfect your water by any one of the following methods prior to consumption (including drinking, cooking, brushing teeth or preparing food):
• Boil water for one full minute in a clean container. The one minute boil time begins after the water has been brought to a rolling boil. (The flat taste can be eliminated by shaking the water in a bottle or pouring it from one container to another.);
• If the water is clear, mix 1/8 teaspoon of unscented, liquid chlorine laundry bleach with one gallon of water and let it stand for at least 30 minutes prior to consumption;
• If the water is cloudy or colored, use 1/4 teaspoon per gallon of water. Be sure to mix thoroughly. If treated water has too strong a chlorine taste, it can be made more palatable by allowing the water to stand exposed to the air for a few hours or by pouring it from one clean container to another several times.
Boiling is the most effective method of disinfecting water, particularly for people who are severely immunocompromised (infected with HIV/AIDS, cancer and transplant patients taking immunosuppressive drugs, or anyone born with a weakened immune system) and for infants and the elderly who wish to take extra precautions.
People obtaining water from a public water system (a system providing water to 15 homes and businesses or more) must continue to disinfect their drinking water by one of the above listed methods until a public notice is issued by DHH that the water has been tested and is safe to drink. It may take as long as three weeks before a water system is declared safe.
People who have been affected by loss of water service may expect some irregularities with their water while efforts are being made to ensure that the water is safe. It is expected that water may have an unusual chlorine odor as well as possible sediments appearing in the water while these special precautions being taken. Flushing household taps for a few minutes should fix this problem.
