Quick Answer
Collect snow for drinking by scooping it into a clean container, then melting it over a fire or in a solar still. Use a clean water filter or purification tablets if the snow may be contaminated. Ensure the melting process doesn't introduce bacteria or other contaminants.
Collecting and Melting Snow
When collecting snow for drinking, it’s essential to use a clean scoop or shovel that won’t contaminate the snow. Scoop the snow into a clean, waterproof container to prevent seepage and contamination. For melting, use a solar still, which involves placing the snow in a container and covering it with a clear plastic sheet. Weigh down the center of the plastic with a rock, allowing the sun’s heat to melt the snow and collect the water in a separate container. Alternatively, you can melt the snow over a fire, using a metal container or a hole in a rock, but ensure the container is at least 6 inches off the ground to prevent contamination from the ground or fuel.
Purifying Melting Snow
If you’re unsure of the snow’s purity, it’s crucial to purify the melting snow before consumption. One method is to use a water filter, such as a LifeStraw or a Sawyer Mini, which can remove bacteria, viruses, and other contaminants. Another option is to use purification tablets, such as chlorine or iodine-based tablets, which can effectively kill bacteria and viruses. When using purification tablets, follow the manufacturer’s instructions, typically 2 tablets per 1 liter of water. Allow the treated water to sit for 30 minutes before consumption to allow the disinfectant to work. Always test the water for purity before consuming it, and if in doubt, err on the side of caution and purify the water.
