Boiling: Bring the water to a rolling boil for 3-5 minutes.  Let cool before drinking.

Disinfect: You can use household liquid bleach (regular household bleach contains 5.25% sodium chloride) to kill microorganisms. Do not use scented, color-safe or bleaches with added cleaners.  Add 16 drops of bleach per gallon of water, stir and let stand for 30 minutes.  If the water does not have a slight bleach odor, repeat the dosage and let stand another 15 minutes.  The only agent used to purify water should be household liquid bleach. 

Distillation: Fill a pot halfway with water.  Tie a cup to the handle on the pot’s lid so that the cup will hand right side up when the lid is upside-down. Make sure the cup is not dangling in the water.  Boil the water for 20 minutes.  The water that drips from the lid to the cup is distilled.
