Survival and preparedness is not all about zombies and being all “tacticool”. Often it is as simple as having water that is safe to drink. A well known method for disinfecting water is with common household bleach. Bleach is inexpensive and readily available at any grocery store.
Why bleach? Most municipalities use chlorine as part of their system to sanitize water for human consumption. Sodium hypochlorite is the active ingredient in bleach and is the source for chlorine. It is important when selecting bleach for water purification to only use regular bleach. Do not use scented bleach as you will be consuming the chemicals used for that feature.
How much to use?
|Treating water with household bleach containing 5.25-8.25 percent chlorine|
|Volume of Water to be Treated||Bleach Solution to Add|
|1 quart/1 liter||5 drops|
|1/2 gallon/2 quarts/2 liters||10 drops|
|1 gallon||1/4 teaspoon|
|5 gallons||1 teaspoon|
|10 gallons||2 teaspoons|
The recommended guidelines listed above come from numerous government sources. Many survival/preparedness websites have been suggesting a lower quantity of 2 drops per quart. This is probably just fine depending on the contamination level. Regardless – allow the treated water to sit for 60 minutes prior to consuming.
If water is cloudy or contains particles/sediment filter through a coffee filter, t-shift, or similar material prior to treating. It is worth noting is that bleach has no effect on chemical contamination.
Lastly – if boiling water is a possibility I would choose that method for purifying water over bleach.
