WATER FILTRATION DEVICES

If the water you find is also muddy, stagnant, and foul smelling, you can clear the water with a filtration device--

• By placing it in a container and letting stand for 12 hours.
• By pouring it through a filtering system.

Note: These procedures only clear the water to make it more palatable. You will still have to purify it
To make a filtering system, space several inches or layers of filtering material such as sand, crushed rock, charcoal (from your fire) in a hollow log, or an article of clothing or other  cloth. Charcoal also removes any odour. Let stand 45 minutes before drinking it.
