Pure water contains a minimum of impurities, there are no heavy metals and elements harmful to human health, it is considered soft. Such water flows in the water pipes of Switzerland and many European countries. It can be found in some bodies of water that have not yet been contaminated by humans: for example, Baikal and Blue Lake in Australia.
What is clean water?
Pure water is distilled, moderately hard or soft water without heavy metals and other elements: fluorine, iron, carbonates. This does not mean that it should not contain any substances: some mineral salts and other elements only improve the properties of water. The main thing is that it meets the hygiene standards adopted by the World Health Organization. Pure water can be drunk without consequences for human health, it dissolves toxins in the body, easily passes through the kidneys, leaving no inorganic compounds and not contributing to the formation of stones.
The cleanest water on our planet is enclosed in clouds and pours on the Earth in the form of rain (unless, of course, there are no pollutants nearby). In the mountains, in forests and other places far from civilization, you can not only wash yourself with such water, you can drink it. But in cities it is dangerous to use it.
The cleanest tap water
The cleanest tap water flows in Switzerland. In any big city, small town or even small town, tap water is of the highest quality - it can be compared to good bottled water that is sold for drinking. Its composition has been well studied by various associations and organizations that monitor hygiene standards: it is not just pure, but mineral, it contains useful salts that have a therapeutic and prophylactic effect. Moreover, the Swiss consumer federation encourages the inhabitants of this country to drink tap water, as it is healthier and cleaner than bottled mineral water. And several hundred times cheaper.
Almost all Scandinavian countries can boast of high water quality: these are Norway, Finland, Sweden. Good water in France and Luxembourg: here they use the purest underground rivers and springs with an admixture of minerals. In Austria, water flows from artesian springs in water pipes, and in Italy you can safely drink water not only from the tap, but also in a fountain on the street.
The cleanest water in the reservoir
The cleanest body of water is considered to be the Blue Lake in Australia, so named because of its rich azure hue. Scientists have carefully studied the composition of the water in it and found that it does not contain any impurities: this water can be drunk without fear directly from the lake. It is so transparent that you can see the bottom ten or more meters away. Researchers have traced the path of water replenishment in this reservoir: it passes through a natural filtration system, getting rid of pollutants.
Russia has one of the cleanest bodies of water in the world: Lake Baikal. Its water contains a negligible amount of impurities and dissolved substances, as a result of which it is possible to distinguish stones lying at the bottom forty meters from the surface. It contains about 96 milligrams of mineral salts per liter, which brings its properties closer to distilled water.
