Strain any sediment through layers of paper towels or clean cloths, before purifying.
Boiling water is the safest way of purification, if you are able. Bring water to a rolling boil for at least 10 minutes.
Using a water purification device, like those sold for camping is another method. The smaller the number of the micro-filter, the better. A micro-filter of 0.3 microns is really good. These devices are compact and can be used to purify as much as 200 gallons or so, depending on the water quality, before replacing the filter.
Chlorination is a method of purification using liquid chlorine bleach to kill microorganisms in the water.
Use liquid bleach that contains 5.25% sodium hypochlorite and no soap.
If other chemicals, such as iodine or water treatment products do not contain 5.25% sodium hypochlorite as their only active ingredient, they should not be used!
Use this chart for proper dosage amount.
A medicine dropper is recommended if available, otherwise you can use a spoon and a thin strip(about ¼ inch X 2 inches) of paper or cloth. Put one end of the strip in the spoon, with the other end hanging down about ½ inch below the scoop of the spoon. Put bleach in the spoon and tip it gently. The drops will drip off the end of the strip into the water.
Stir the water and let stand for 30 minutes.
If the water doesn’t have a slight chlorine taste and smell, use another Clear Water dose and let stand another 15 minutes.
minutes. Let it cool before drinking. If the water tastes flat you can re-oxygenate it by pouring the water back and forth between two containers, several times.
