Summary
Rock boiling: heat rocks in a fire, then place them in
your water container (with water) and boil the water.
Construct a filter from a cone of birch bark, fill it
with grasses and sand in layers. Unfortunately, this doesn't
get rid of pollutants.
Construction of a solar still will help to naturally
purify water. Just pour the contaminated water next to the
solar still (not in it), and the filtered water will be drawn
right out of the ground and collected in the cup in the
still. The same can be done with human urine.
