As you know, there is no life without water. The human body must be constantly replenished with water, especially in the campaign, when a tourist on the move, which results in excessive sweating. At home, the replenishment of the body often occurs due to water vegetables, juices and other sources, which is practically devoid of tourist campaign. The ability to find drinking water in the field is very important for the traveler. Best water — spring, but in a way more common rivers, lakes, ponds and reservoirs. Dig a hole next to the water and wait a few minutes until it is full of cleaner, filtered through the ground water. During the period of high water and snow melt water from lakes and streams do not require cleaning. In winter, the water can get out of the snow, collecting it in a metal pot and melt in the fire. Intense boiling — the most radical method of purification from bacterial pond and swamp water. If you boil the water once, it can be partially neutralize a few drops of iodine or potassium grains (water is almost to be painted). There are also special tablets for disinfecting water is not boiling swamp. But we should not get involved in such water. To provide cold drinking water the whole group is better to boil, then pour into a flask or aluminum cans, wrap them dense material (cloth, towel, handkerchief) and abundantly watered from the top, so that the material it is soaked, hang water bottles in the background, it is desirable to wind: the water is cold, even in hot weather. In a way, especially during the day, a flask of water and a wet towel wraps periodically wet. If you are in the area, where there are no streams or lakes or wells, — do not despair. We must make an attempt to find water. Start digging in the lowlands, the hollows at the foot of the dunes on the leeward side. If you see a dark wet sand or clay, then after a while the hole fills the groundwater. In the mountain-desert water source can be found at the foot of the plateau, on the steep slopes. Places the water sweat covering thick drops of rock or hidden under a thin layer of soil, covered with bright green vegetation. Often, after the rain water collects in the depressions at the base of the cliffs, on the edges of pebble placer. On. proximity of groundwater sometimes indicate clusters of midges and mosquitoes after sunset, as well as bright green patches of vegetation of sun-baked steppe. These indicators include broadleaf cattail, sitnyag, common reed, bulrush and timber, creeping buttercup, meadow foxtail, sand sagebrush, knotweed pochechuyny, a series of tripartite, sorrel horse, wild rose and other plants. , If you have an adequate supply of water, keep in mind that to maintain the water balance of the body of water should be proportional to the ambient temperature. So, with an air temperature of 50 degrees at night consumed 2.9 liters of water, 44-1,9, at 38 -: 1.6, at 33-1,4, 28-1,3 in at 22 degrees-1 , 2 liters.
