Chlorine Bleach

All water has a perfect memory and is forever trying to get back to where it was. - Toni Morrison

How to use Chlorine Bleach for Emergency Water Purification:

Treating water with bleach is very effective at killing germs. For chemical disinfection to be effective, the water must be filtered and settled first Chlorine disinfectant work much better in warm water.

You need to have a bottle of plain liquid chlorine bleach and a dropper. The bleach should be 5 to 6 percent sodium hypochlorite with no preservatives and no additional ingredients. Do not use scented bleaches, color safe bleaches, powdered bleaches, or bleaches with added cleaners. It can be hard to choose because bleach is now available in different concentrations. Ultra Clorox is a 6% solution instead of 5.25% but it is the same stuff. Keep a bottle of plain 5.25% or 6% chlorine bleach with no additives to use for water purification.

To treat water with chlorine bleach, put the water in a clean container and add 16 drops of bleach for every gallon of water. Stir in the bleach and let the water stand for 30 minutes. If the water does not have a little smell of bleach, repeat the dosage of 16 drops per gallon and let it sit for another 15 minutes. If it smells of bleach now it is OK to drink. If it doesn't smell of bleach after two treatments, the water is too dirty to use. Throw it away and treat a new batch of water.
