Good indicators of sources of fresh drinking water are birds, animals, insects. All birds that feed on cereal plants, such as finches, wild pigeons and others, do not fly far from the water.
Indicators of the availability of sources of fresh drinking water, safe and dangerous water.
About the direction in which the water source is located, the nature of their flight can tell. Direct and low means, most likely, they fly to the water. Unhurried, broken, from tree to tree, with frequent rest usually means that birds return from sources of water. In the first case, it is necessary to move in the direction of flight, in the second in the opposite. Birds circling over one place or singing songs can also indicate the source of water..
, therefore, they cannot serve as indicators of water sources, since they are capable of moving away from water over long distances. Water birds are also able to make long flights without stopping to refuel with water and food, and therefore it is better not to focus on them.
Most mammals need regular water intake. Herbivores are especially attached to water. Imprints of their hooves and paws, converging in one place, can lead to a water source. Carnivores are able to do without moisture for a long period of time, as they get it together with the meat of eaten animals. Therefore, focusing on them, as conductors to water, is more risky than on their herbivorous relatives. Likewise, reptiles are not indicative of water. It is enough for snakes and lizards to maintain water balance in the body of the dew and moisture deposited in the bodies of the eaten victims falling in the morning.
More reliable indicators of water sources and moisture insects. Bees do not fly far from the water. Their maximum flight under normal conditions does not exceed 6.5 km. Most species of flies and mosquitoes cannot do without water. An exception can only be cases when they were carried away far from the water source on the eve of the past storm. The so-called European, with an iridescent green abdomen, the fly generally does not move away from water sources further than 100 meters. Flying waterfowl are also tied to open water. A column of ants moving in the same direction in an arid area can lead to a hidden source of water, for example, in a hollow of a tree standing not far from an anthill.
Safe and dangerous water.
The most safe from a medical point of view, and also tastes good, the water in the keys and springs. Having broken through the thickness of the earth, water is purified from harmful impurities, microorganisms. Such water can be drunk without any fear. The same can be said of most flowing reservoirs with fast flowing streams, small plain and mountain rivers. Most of these water sources feed groundwater or glaciers. They flow in the middle of the forest and therefore simply do not have time to get polluted.
In deserts, sometimes there are small lakes, hollows filled with water that has a salty or soapy taste. It is unsuitable for drinking. Inorganic salts and other impurities contained in it (more than 4-5 g / l) cause acute intestinal disorders, which contribute to increased dehydration. Such water can only be used to wet clothes. Or you need to distill this water before drinking.
Unlike fast-flowing streams and rivers, low-flowing bodies of water (wide flat rivers, elders, overgrown lakes, ponds, swamps) cannot offer ready-to-drink water to disaster victims. Stagnant water is usually heavily contaminated and saturated with various pathogens. It is better to play it safe and if you drink it, then after appropriate and very thorough processing.
Any body of water should alert you if there is no greenery around it or animal bones are lying around. Most likely, the water in it is infected. In an extreme case, when there is no other way to escape from anhydrous death, it is permissible to desalinate such water with the help of solar condensers and distillers. Precipitation water accumulates above groundwater and forms streams, ponds and swamps. Consider this water contaminated and dangerous, and it is better to endure thirst until there is a spring or other clean body of water on the way. At the same time, to reduce thirst, you can suck bones from the fruit or a clean pebble-naked.
A doubtful spring with running water can be checked by an old Cossack trick to spit in the water and see how saliva behaves in it. In pure water, saliva should quickly diverge and dissolve, in contaminated ones it often stagnates. It is clear that such an express analysis is not able to detect all pathogens, so it is better to be safe and boil dubious water. It is permissible to rinse your mouth with water unsuitable for drinking (just do not swallow it in any case), wipe your face, neck, and moisten your hat. Those who sweat a lot, it is advisable to eat 10-15 g of salt in the morning, washed down with water until it feels full. This will facilitate their condition during the daytime transition..
