How to Purify Water with Bleach


This article will instruct you on how to purify water with bleach. If boiling water takes too much time and energy there are other ways to purify water. While purification tablets make the most sense, if you are thrown into a survival scenario – you will most likely not have access to them. Survival doesn’t necessarily mean you are in the wilderness, so you may have access to something as simple and common as bleach.

Purify water with bleach if boiling isn’t an option. Bleach contains chlorine which is already present in most people’s drinking water today, so if used in small amounts it will not hurt you. Here are the rules for cleaning water with bleach.

For 1 liter of water add 1 drop of 10% strength or 10 drops of 1% strength. Add 5 drops of 10% strength per gallon or 10 drops of 1% strength per gallon. Bleach will not always kill everything but it’s certainly better than using nothing. For a good rule of thumb, a tablespoon of bleach per gallon of water will not hurt you at all, so be generous with the amount you use. Be sure to shake the water and bleach mixture and let it sit for 20-30 minutes after mixing.
