Use the following methods to purify water.

Water can be purified quickly and cheaply by adding chlorine bleach to it. to purify a liter of water, do the following.

1. Get a large clean container and label it “drinking water”

2. Fill it with one liter of water. Add four drops of chlorine bleach. Bleach used for this purpose should contain 4 to 6 percent sodium hypochlorite. If you can only get bleach with 1 percent sodium hypochlorite, you must add twenty drops of bleach to a litter of water.

3. Cover the container with a clean lid or cloth. Let the water stand for thirty minutes.

4. Taste the water and notice the faint chlorine taste. If there is no chlorine taste, add two more drops of bleach. If the chlorine taste is too strong, pour the water back and forth from on clean container to another to improve the flavor.

Water can also be purified by boiling it. Bring the water to a rolling boil, and let it continue to

boil for thee to seven minutes.

You may be able to purchase iodine tablets or other chemical purifiers to purify small amounts of

water for use while hiking or backpacking. Follow the instructions on the label carefully, and

make sure that the tablets are not outdated.

Camping suppliers offer water purification filters for use with small amounts of water. Carefully

follow the instructions that come with the filter. Once you have purified some water, make sure

that no germs or parasite eggs get in it before you use it. Keep it in a clean container covered with

a lid. Use the purified water when preparing meals. You cannot kill germs by adding chlorine

bleach to fruit drink after it is made. Broths and drinks that are boiled are purified by the boiling.

Boiling: Boiling has been the traditional way to treat water. It does a good job of killing

parasites, bacteria, and viruses but it does not neutralize any chemicals or improve the taste. The

drawback is that this method requires a LOT of time and fuel. To use this method, boil water 5-

10 minutes plus one minute for every thousand feet over sea level.

Sodium Dichloro-s-triazinctrione- 99% and 1% inert ingredients powdered bleach.

2 lb container of soduim dichloro-s-triazinctrione costs $15-20.00 and will clean up to 160,000

gallons of water, enough for your family and you will have sufficient to share with extended

family, friends and neighbors.

• Its advantages, only 1/4 teaspoon is used to treat a 55 gallon drum of water and the shelf

life of a container of this concentrate is 15 to 25 years if kept dry and stored in a cool

location.

• Two oz treats 10,000 gallons.

• Dissolves instantly with no residue.

• Clears up water fast and keeps it clear.

Instructions for Use: Add 1/4 teaspoon of the chlorinating concentrate to your 50 or 55-gallon

drum. Place the cap on the container and seal it, and allow the water to sit for 24 hours. After 24

hours, remove the lid and test for the presence of free chlorine in the water. This can be done by

smelling, or by using test strips for free chlorine, available at pool and spa stores. These test

strips cost about $10.00 for 50 strips. If the chlorine can be detected after 24 hours, then the

water has been purified. At the point, remove the lid from the water container and allow it to sit

open for another 24 hours. The free chlorine will come out of the water, and the water is then fit

for drinking. If no chlorine is present after the first 24 hours with the container closed, repeat the

process, as organic matter (bacteria, cysts, etc.) Are still present. Until free chlorine can be

detected after 24 hours, there are probably organisms still present.

When water is heated to 165 degrees for 10 minutes it kills all bacteria, parasites and viruses.

Water is pasteurized most quickly (@ 2 hours in mid-day) when put in black bottles or thin black

pots w/ lids in a solar oven (funnel, CooKit, or other solar oven). If NOT using a solar cooker,

then it could take 4-6 hours to pasteurize. Let cool before drinking.

WAPI’s are used to monitor water pasteurization. These are small tubes with soy wax in them

that acta s a kind of thermometer. When the wax melts and goes to the bottom you know it is safe

to drink.

Cut tubing into lengths of 2 ½”. Use PVC pipe cutters (easiest). Using a small propane torch,

heat one tube end and crimp closed with a pair of pliers and let cool. Put wax inside tube (about

3/8" of wax) and add large washer over non-crimped end. Using the propane rorch, heat opposite

end of tube and crimp using pliers. Let cool. Drill 1/32" diameter hole in each flattened end of

tube. Cut fish line to 15" lengths. Tie one small washer (3/8" OD) to one end of fish line. Thread

this line through one end of the tube, up along side of tube, under and through the large washer,

and through the hole at the opposite end of the tube. Tie a small washer (3/8" OD) at opposite

end of fish line.

Aerobic Stabilized Oxygen : (oxygenforlife.net) Aerobic Oxygen is safe, non-toxic, and

destroys harmful bacteria without the need to boil the water. Unlike chlorine or iodine, Stabilized

Oxygen acts selectively and DOES NOT harm beneficial aerobic bacteria which is needed for

good health. It kills any infectious disease such as: Salmonella, Cholera, E.Coli, Streptococcus,

Pseudamonas, and Staphyloccus A and Giardia-Lamblia.

oz. Of questionable water; 20 drops per gal. for water storage. ½ bottle per 55-gallon barrel.

Bacterial contamination on food: 60 drops to a gal. of water, spray or dip food for 30 seconds or

more. It can be sued as a “natural” antibiotic and to disinfect scratches, cuts and minor wounds. It

has an unlimited shelf life. (WaltonFeed.com $18)

Ozone: Ozone, aka O3 is made with oxygen and electricity. It is many times more powerful as a

purifier than bleach. The down side is it needs electricity and has a short life span. Ozone is used

to purify all bottled water we buy. Ozone machines cost as little as $150 or a house unit for about

$1,500.

Micropur Tablets: the only purification tablets that re EPA registered on the market. They are

effective against viruses, bacteria, cryptosporidium, and Giardia. Unlike iodine tablets, these

tablets leave you with only the taste of fresh water. Each tablet treats up to one liter of water,

eliminating all micro-organisms. Tablets come in a bottle of 30. (Beprepared.com $13)

Polar Pure Water Disinfectant: It uses pure crystallized iodine in a unique delivery system to

destroy water-borne pathogens including giardia cysts and micro-organisms (viruses) that pass

through filters. Iodine creates health problems for some people, including: thyroid problems,

allergic, pregnant women, but is safe for others for 3 months if no filtering after treating. Works

well in extreme temperatures, will treat 2000 liters of water, stores indefinitely.

Distillation: It is a process of boiling the water and collecting the evaporated of water. This

method does not remove all chemicals but it does give you clean water from polluted or salt

water. The easiest form of distillation is solar but you can also boil it. This method does not make

much water nor does it taste very good. 1.2 hours to distill 1 gallon of water. (That is a lot of

fuel) Cost: about $300 for non-electric.
