Water is the most important natural resource: problems of its quality

Fresh water has become one of the world's most valuable resources.
The issue of water scarcity is very relevant. The indicators of its quality and the level of water reserves in the world are no less important.
Water is a natural resource that receives little attention from the world community.
In the modern world, there is a very shortage of clean drinking water. In some countries, entire areas where people live suffer from this. They have to travel tens of kilometers to get water.
The earth is two-thirds covered with water, its total volume is 1386 million cubic kilometers. On the other hand, it is clear that the problem is not the quantity but the quality of the water.
Fresh water reserves on Earth are only about 35 million cubic kilometers. Only one hundredth of these reserves are within walking distance for humans. Extraction of water resources requires serious material and labor costs and this is not the main problem. Humanity needs the rational use of even existing water supplies.

Distribution of water resources of the world

One third of all fresh water reserves are concentrated in South America, a fourth of it is in Asia, and the countries of Eastern Europe account for just over 20%. To the Middle East and North Africa about 2%.
The largest consumers of fresh water are India, China, USA, Pakistan, Japan, Thailand, Indonesia, Bangladesh, Mexico and Russia. A particularly acute shortage of drinking water is observed in China, India and throughout Africa.
In addition to the lack of fresh water, there is another urgent problem - its quality. Its deterioration directly depends on the increased level of environmental pollution. In most cases, this is due to human activities and overpopulation.

Major sources of water pollution

Plastic pollution of the planet. Is there life without plastic?
40% of water pollution comes from industry. The activities of public utilities, washing off of fertilizers from agricultural land, "acid rain" and other anthropogenic "natural" phenomena also play a role in pollution.
The main source of freshwater pollution is oil and oil products. Oil can get into water and in places of its occurrence. In most cases, this pollution is caused by oil production, transportation, processing and the use of raw materials as fuel.
Industry also severely degrades the quality of fresh water. Every day, its quality deteriorates due to the release of toxic substances. They appear in the form of a layer of foam, which is especially noticeable on rapids, at locks and rifts.

 

Modern methods of water purification

Heavy metals such as mercury, lead, copper and manganese are strong pollutants in fresh water. For the environment and human health, the greatest threats are posed by mercury, lead, cadmium and their compounds. All this makes it difficult to use fresh water, even for domestic and industrial purposes, without preliminary purification.
Scientists Explain Why People Buy Bottled Water
To date, there is no single universal method for purifying fresh water - its choice depends on the composition of the water, the requirements for it and the scope of its further use. For example, there are ozone, osmotic, filtration and ionic purification systems, each of which has its own pros and cons. The most promising so far is the nano filtration technology. This method will effectively eliminate even halogen organic and chlorine-containing impurities in water without the use of aggressive reagents. Nano filtration is used in Holland, USA and France. This method is one of the most expensive, so it is not widely used. Even in countries where nano filtration technology is used, they do it only for purifying water with a special purpose.

The problem lies in the fact that fresh water is being extracted from soil or rivers in these parts of the world faster than its renewal.
The extraction and production of a vital resource requires serious technological development, investment and time. Developed countries can do this, but here a problem arises - less developed countries will become even more dependent on the world's "giants", and many densely populated poor regions of the planet will completely turn into a lifeless desert if the problems with access to water are not resolved.
That is why the countries of the first world have already embarked on the path of careful, rational and efficient use of fresh water, having developed and enacted special laws on the protection of water resources.
Our organization purchases and distributes individual and collective water purification equipment to disadvantaged polluted areas of the planet.

We need sponsorship for the purchase of water purification equipment.
We will be very grateful that you will contribute to an ecological project to purify the water of our planet.
