WATER FILTRATION DEVICES
If the water you find is also muddy, stagnant, and foul smelling, you can clear the water--
- By placing it in a container and letting it stand for 12 hours.
- By pouring it through a filtering system.
Note: These procedures only clear the water and make it more palatable. You will have to purify it.
To make a filtering system, place several centimeters or layers of filtering material such as sand, crushed rock, charcoal, or cloth in bamboo, a hollow log, or an article of clothing (Figure 6-9).
Remove the odor from water by adding charcoal from your fire. Let the water stand for 45 minutes before drinking it.
