Wheather snow water is useful for the people is depend upon various parameters like climatic condition, type and health of people and their age. Quality and quantity of snow and many many more. However it's usefulness varies people to people and one country to another.

Dear @Virendra Kumar Saxena,

Thank you very much for  opinion.

In some areas, rain could make up the difference in the snow deficit, with rain increasing even as snow decreases. But other areas face a more challenging future. In 32 of those drainage basins, snowmelt is the primary source of water for the 1.45 billion humans that live there. Relying so exclusively on that single source of water means that a dry or warm winter could have disastrous consequences in the future. Among the areas at risk are the drought-stricken American West, areas of Europe from Portugal to Italy, countries in Asia, Morocco, and perhaps most worryingly, areas of the Middle East, including Syria, and parts of Saudi Arabia and Iran. Adding additional stress to a volatile region is a worrying issue for international security

Dear @Sathish Dhandapani,

Thanks a lot of for answer.

Yes is useful 

Basically, you will have to find a clean source of ice or snow and you’ll have to melt it in order to quench your thirst. Keep in mind that it will take some time and energy to procure water, so don’t wait until the first symptoms of dehydration appear: start early, plan ahead.

First, you must be aware of the fact that snow and ice are as pure as the water from which they were born. Also, keep in mind that snow tends to retain all the impurities in the atmosphere; hence, you should avoid snow that looks contaminated with traces of dirt or other dubious debris.  Another thing to remember is that ice will give you more water than snow, all things being equal, because it has a much higher density than snow. So, basically, go for ice instead of snow, if possible.

Dear @Mushtaq Ahmad,

Thank you very much for interesting opinion.

In general, yes.

In a study published in Environmental Research Letters, researchers found 97 drainage basins that depend on snow melt for their annual allotment of water. The researchers examined 421 basins, but focused on these 97 basins because they not only supply fresh water to 2 billion people, but there is also a 66 percent chance that the snow available to those basins would decline in the coming years.

In those areas of the world, snow during the winter acts as a watery savings account for warmer, drier months. When snow melts in the spring, it fills rivers and streams, providing a steady, seasonal water supply.

Dear @Aristidis Matsoukis,

Thank you very much for informative answer and links.

Dear

I assum that snow water is useful for people. According to United States Department of Agriculture (USDA) Snow Water Equivalent (SWE) is a common snowpack measurement. It is the amount of water contained within the snowpack.

Dear colleague

 Although snow is less important than rainfall, the presence of a snow pack can be a very important source of water in the forest. Melting snow that serve as a critical habitat for many forest amphibians.

The snow that accumulates during an average winter also insulates the soil underneath it keeping the soil largely unfrozen and able to absorb water from melting snow. Most of the snowmelt water entering the soil infiltrates deep below the surface where it recharges ground water aquifers .

Ground water aquifers by melting snow provide water supply wells and streams with a steady source of cool ground water during the long, hot summer. Fish and other stream life have adapted to the increased stream flows in spring and the relatively cool ground water that is supplied to the stream throughout the summer. Without this spring recharge, stream levels may drop and stream temperatures may increase to dangerous levels during the summer.

Dear @Musab A. Al-Tarawni ,

Thank you very much for comments and link.

With the onset of cold weather and the first snow of many people once again became interested in the question of use of melt water. Many people know that the freeze allows you to structure the water molecule, and the question arises, it is good to our body affects slush?

For a long time it is known that the snow water has unique properties. This has been proven not once modern scholars. So, in the course of experiments it was found that the melted snow water watering can increase and improve the quality of the crop. And if you soak the seeds before planting in the melt water, the crop will be more than about three times.

However, to use and to use melted snow water should be as carefully as negligence in this regard may result in the emergence of many diseases.

Snow water is the result of melting snow. It is often also called "living" water. Icy water - it melted the ice that forms in natural waters. Snow water also has a large reserve of energy, because it is fueled by the sun, and receives more solar energy and which has beneficial effects on the body. All the benefits and importance of such a liquid is that it is easily digestible for the organism. Such water is dense enough, and for this reason is not too saturated with salts. This means that the water is soft snow, unlike water or borehole.

Snow water is useful in such cases:

Polyarthritis.

High blood pressure.

Diseases of the digestive tract.

Obesity.

Varicose veins.

Skin diseases.

In order to completely rid the body of unwanted toxins and salt, it takes an average of six months to a year. To start with heals and purified the organs that are most intoxicated. Then gradually the salt come from other organs, cleansing the body completely.

Snow water has no contraindications for use. But if you take too long drinking plain water from the tap, then the body will be a long time to get used to, and may experience stress and reducing functions. In order to smooth the transition to a new type of water, do not immediately throw the usual drinking water, and gradually introduce new, listening to your body.

How to drink snow water?

It is necessary to take a fresh snow, or snow, which lay in the shade. In this area, in which you collect it, to be environmentally friendly. Certainly about snow in the city and say no, because in this place it is contaminated by exhaust fumes and other things.

Melting snow should occur in an enamel pot, covered with a lid. In order to everything went rapidly into the container can be placed with a warm water bottle. In this case, you can not put snow on the stove. It should be noted that if the vessel walls will oily residue, then this can not drink the water, snow and must be discarded. Once the snow turns into water, it should be filtered. It is possible with a simple gauze, but you can with the help of the carbon filter. Clean water should be emptied and closed in a jar with a tight lid.

Before you drink this water, it is necessary to boil, and as soon as the first bubbles start to appear - turn off.

Snow water is considered to be distilled, and therefore it does not have any - any taste or smell, and in order to give it some color, you can add a few drops of lemon or honey.

Drink this water for half an hour before eating in the morning on an empty stomach.

Keep this water may be no more than seven days after it loses its beneficial qualities.

"Snow is important because it forms its own reservoir. But the consequences of reduced snowpack are not the same for all places—it is also a function of where and when people demand water," lead author Justin Mankin, a postdoctoral fellow at Columbia University’s Earth Institute said in a statement. "Water managers in a lot of places may need to prepare for a world where the snow reservoir no longer exists."

In some areas, rain could make up the difference in the snow deficit, with rain increasing even as snow decreases. But other areas face a more challenging future. In 32 of those drainage basins, snowmelt is the primary source of water for the 1.45 billion humans that live there. Relying so exclusively on that single source of water means that a dry or warm winter could have disastrous consequences in the future. Among the areas at risk are the drought-stricken American West, areas of Europe from Portugal to Italy, countries in Asia, Morocco, and perhaps most worryingly, areas of the Middle East, including Syria, and parts of Saudi Arabia and Iran. Adding additional stress to a volatile region is a worrying issue for international security.

I agree with the answer of Dr. Aristidis Matsoukis.

Dear Shafagat

Drinking water made from clean white snow melt is generally considered safe because pathogens don't usually survive in it. But that's not always the only consideration. In areas with lots of traffic like outside of well-used huts or in patches of late-season snow there may be added pollutants that you'd want to filter or otherwise clean out.

For the best results, pull fresh, clean-looking snow from a designated "drinking snow" area away from traffic zones, toilets, or dish pits. Also, add a little water to the it before heating up your melting pot, which can scorch and taint the water with a bad taste. Boiling water, which is the most effective method for disinfecting it, is often part of making coffee or warming up in winter, so if you do end up heating the water to that point you'll get some peace of mind no matter where you got it.

Glaciers provide drinking water

People living in arid climates near mountains often rely on glacial melt for their water for part of the year. Many of the rivers coursing through China, India, and other parts of the Asian continent are fed largely by snowmelt from the Himalaya, but in late summer a significant part of riverflow comes from melting glaciers. In South America, residents of La Paz, Bolivia, rely on glacial melting from a nearby ice cap to provide water during the significant dry spells they sometimes experience.

Dear Shafagat Mahmudova ,

yes.

i think this link will good,

I agree with Shafagat madam's answer

As stated by Dr Sheth

If the wastewater has become a resource, despite its pollution, it is certain that pure water of snow is better.
