Purifying Water

If water contains sediment or floating material, strain it through a cloth before purifying it.
  • If you have access to heat or power, boil water at a hard boil for 10 minutes. Cool. Store in clean containers with covers.
  • If you have no access to heat or power, treat the water with chemicals (chlorine bleach or water purification tablets).
    • Chlorine bleach – Add 1/8 teaspoon (or eight drops) of regular unscented liquid household bleach containing 5.25 percent sodium hypochlorite for each gallon of water.
      • Stir well and let stand for 30 minutes before use.
      • Store disinfected water in clean containers with covers.
    • Water purification tablets – Purchase them at drugstores or camping/sporting goods stores. Carefully follow the manufacturer’s instructions. Purification tablets are for emergency use only, not everyday use.
