The easiest and most simple way to collect water is through precipitation like rain or snow. Always melt snow before drinking so that it doesn’t lower your body temperature. Dew can also be collected early in the morning where there is a lot of dew-covered foliage. Walk through the area with a shirt wrapped around your legs, then, wring the shirt directly into your mouth or a container. Transpiration is a water collection method in which water is basically “sweated” out of foliage using a piece of plastic like a grocery bag or garbage bag and cord or string. Find a leafy branch of foliage, bag it up completely with the plastic and secure tightly with string. Water will transpire from the leaves and drip into the bag. Sources that water are collected from generally do not need to be purified.
