https://grandpappy.org/hwater.htm

- Either 5.25% or 6% Strength
Kills Bacteria and Viruses.
Not effective against all Protozoa.
Does Not Neutralize Harmful Chemicals or Radioactive Particles.

Relatively Clear Water - Use 2 drops of bleach per quart of water or 8 drops per gallon (or 1 teaspoon per 10 gallons).
Cloudy Water - Use 4 drops of bleach per quart of water or 16 drops per gallon (or 2 teaspoons per 10 gallons).

The water should not be too cool. The water temperature should be 70°F or higher. If necessary, put the water in direct sunlight to raise the water temperature. The effectiveness of chlorine at killing pathogens diminishes rapidly at lower temperatures.

Add the required number of drops of chlorine liquid bleach (Clorox or store brand, unscented) to the water and wait one hour for the bleach to kill all the tiny organisms. If you can detect a faint chlorine smell in the water at the end of one hour, then it is safe to drink. If you can't smell the chlorine, then add the same amount of bleach a second time and wait another hour. If you can detect a faint chlorine smell, then the water is safe to drink. If you still can't detect the smell of chlorine, then discard the water because it contains too many germs. (Note: Always start with the minimum recommended amount of bleach and add a little more if necessary. Too much chlorine is harmful to your body.)
