Safe Drinking Water


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:

  1. Boil water for three minutes in a clean container.  Water must be at a rolling or vigorous boil for the three minutes.
  2. 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.
  3. 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.
