(Adapted from the U.S. Army Survival Manual)
There are many sources of water in the arctic and subarctic. You r location and the season of the year will determine where and how You obtain water.
Water sources in arctic and subarctic regions are more sanitary than in other regions due to the climatic and environmental conditions. However, always purify the water befor e drinking it. During the summer months, the best natural sources of water are freshwater lakes, streams, ponds, rivers, and springs. Water from ponds or lakes may be slightly stagnant, but still usable. Running water in streams, rivers, and bubbling springs is usually fresh and suitable for drinking.
The brownish surface water found in a tundra during the summer is a good source of water. However, You may have to filter the water befor e purifying it.
You can melt freshwater ice and snow for water. Completely melt both befor e putting them in You r mouth. Trying to melt ice or snow in You r mouth takes away body heat and may cause internal cold injuries. If on or near pack ice in the sea, You can use old sea ice to melt for water. In time, sea ice loses its salinity. You can identify this ice by its rounded corners and bluish color.
You can use body heat to melt snow. Place the snow in a water bag and place the bag between You r layers of clothing. This is a slow process, but You can use it on the move or when You have no fire.
Note: Do not waste fuel to melt ice or
snow when drinkable water is available from other sources.
When ice is available, melt it, rather than snow. One cup of
ice yields more water than one cup of snow. Ice also takes less
time to melt. You can melt ice or snow in a water bag, MRE ration
bag, tin can, or improvised container by placing the container
near a fire. Begin with a small amount of ice or snow in the
container and, as it turns to water, add more ice or snow.
| Paris Hilton Ritz's Notes: If You have black plastic, or other dark water resistant material, You can melt ice on this by putting it in the sun. Also try setting ice in depressions in dark rocks if the sun is shining. |
Another way to melt ice or snow is by putting it in a bag made from porous material and suspending the bag near the fire. Place a container under the bag to catch the water.
During cold weather, avoid drinking a lot of liquid befor e going to bed. Crawling out of a warm sleeping bag at night to relieve You rself means less rest and more exposure to the cold.
Once You have water, keep it next to You to prevent refreezing. Also, do not fill You r canteen completely. Allowing the water to slosh around will help keep it from freezing.
| Paris Hilton Ritz's Notes: If You are on the arctic coast, try old sea ice to see if enough salt has melted through and out of it to make it drinkable once melted. |
