All water in North America should be considered contaminated.
Organic contamination is bacteria from animal or vegetable matter:
Mineral contamination comes from commercial and natural sources.
- Boil at least 10 minutes
- Treat with water purifier
- Distill as last resort (inefficient)
- Tie a plastic bag around a leafy branch, or suspend it over
a bush. Don't let bag touch the leaves. Water will collect at
bottom of bag.
A water "still" can also be constructed. You need a
sheet of plastic, a container & a drinking tube. Dig a hole,
and add vegetation, then douse the ground in the hole with impure
water. It will evaporate and then condense, filling your container
with clean water.
