Water is the single most abundant substance in the human body, making up to 60 percent of an adult’s weight and up to 80 percent of an infant’s weight. A person can live several days without food, but just a few days without water. It is second only to air in importance to life.
Because water is so important to human survival, never ration it. Drink at least 2 quarts per day, as long as supplies last, and look for alternative sources.
If necessary, drinking water may be disinfected by ONE of the following methods:
- Boil water for three minutes in a clean container. Water must be at a rolling or vigorous boil for the three minutes.
- Mix 1/2 teaspoon of liquid, unscented chlorine laundry bleach, such as Clorox or Purex, with 2-1/2 gallons of water. Let stand for at least 30 minutes before drinking.
- Add 2 drops of tincture of iodine to 1 quart water. After mixing thoroughly, allow to stand for at least 30 minutes before drinking.
Use boiled or disinfected water to brush teeth.
