Can Snow Be Used As An Alternative Water Source?

Melted Snow as Drinking Water

Melted snow can be used as drinking water in emergency situations or when access to other water sources is limited. To collect and melt snow, dig a hole in a shaded area or use a tarp to create a makeshift snowmelter. For a small group, a hole about 10-15 inches deep can collect 10-20 pounds of snow, which is equivalent to 1-2 gallons of water.

Purifying Snowmelt

To purify snowmelt, use a water filter or boil the water for at least 1 minute at an elevation of 5,000 feet or lower. At higher elevations, boil the water for an additional 1 minute for every 1,000 feet above 5,000 feet. If a filter or boiling equipment is not available, use sand filtration, solar disinfection, or other proven water purification methods to remove contaminants and pathogens.

Collecting and Storing Snowmelt

When collecting and storing snowmelt, use a clean container to prevent contamination and bacterial growth. Keep the container covered to prevent re-contamination and to maintain water quality. If storing the snowmelt for an extended period, add a small amount of water treatment tablets or liquid chlorine to prevent bacterial growth and maintain water quality.
