Chlorine in water

by Jeff
(United States)

An army friend of mine said he used to carry a small eyedropper bottle full of straight chlorine bleach. He get his drinking water from a clear stream and would squeeze one drop of bleach in his canteen for clear water and two drops if it was cloudy.



He said that since straight bleach is so highly concentrated that it would kill the bacteria in the water, and such a small amount would not have any detrimental effect on the human body.

I haven't been able to confirm this as a viable water purification method.

Any ideas?

Clorine/bleach
by: Anonymous

You can use 2-3 drops of bleach in a quart of water if you cannot boil it and it will kill everything in the water that would otherwise make you sick.

Big bubbles
by: Chuck McKinney

Actually it is not necessary. By the time water reaches 185 degrees most of the biological contents of the water are dead. When the water reaches a roiling boil its ready. Big bubbles no troubles is how they express it in New Zealand and Australia. Chlorine is good if you have it and can't boil your water.

Boiling
by: Janeen

This is the best way to purify water - boiling. However, you don't have to boil for 20 minutes. Boiling for 3 to 5 min is enough to kill bacteria. Boil 5 to 7 min in high altitudes.

More on chlorine and water
by: Charles McKinney

With chlorine, two drops per quart of clear water and 4 drops per quart of cloudy water is the recommended dosage. Cold water, sunlight, particulates and high PH will all slow down the effect of chlorine.

Treat the water, wait 30 minutes, sniff the water, if a slight chlorine odor you're good to go.

If not then add another dose of chlorine and wait another 15 minutes and sniff again.

If still no odor of chlorine discard the water because something is neutralizing the chlorine and the water will NOT be purified.

I have used this and drank the water. I am not dead yet not had any ill effects from water. Take pure water with you but if you need this method it is good.

Bleach is recommended by Red Cross
by: Anonymous

From American Red Cross
http://www.redcross.org/services/prepare/0,1082,0_91_,00.html#sources


Disinfection: You can use household liquid bleach to kill microorganisms. Use only regular household liquid bleach that contains 5.25 percent sodium hypochlorite. Do not use scented bleaches, colorsafe bleaches 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 treat water should be household liquid bleach. Other chemicals, such as iodine or water treatment products sold in camping or surplus stores that do not contain 5.25 percent sodium hypochlorite as the only active ingredient, are not recommended and should not be used.

Chlorine Purification
by: Anonymous

I just finished reading an interesting book called 98.6 Degrees The Art of Keepin Your Ass Alive by Cody Lundin. In the book, it talks about purifying water with chlorine and this is what he had to say: Quote, "In the case of sodium hypochlorite 5.25%, otherwise known as chlorine bleach, organic matter bonds with the chlorine itself, and actually changes its chemical makeup into something called chloramine, which doesn't do jack to disinfect your water. This is just one reason why chlorine sucks for field water disinfection." Lundin's recommendation for purifying water is in the use of Tincture of Iodine 2%. Just another point of view I found.

Sounds Like a Good Idea

That would definitely help keep your survival kit light-weight. Now we just need to get this confirmed and I can add it to my own survival kit.

Chlorine causes the runs.
by: Anonymous

The problem with using chlorine bleach is if you ingest too much chlorine in that form you will get a mean case of diarrhea. This will defeat the purpose of purifying water. The best way is to boil the crap out of the water. 2 minutes minimum at a full boil.
There is also much safer commercially prepared water purification tablets that are inexpensive.

Clorine and Iodine
by: Ned

Using chlorine is one of two common method of chemical treatment for water purification. The other method is using iodine.

Remember that chemical purification methods may only be partially effective, depending on the water temperature, pH level, and clarity of the water. Cloudy water often requires higher concentrations of chemical to disinfect.
