        WATER AND WATER RESOURCES

* WATER CYCLE*

Su sevkıyat veya hidrolojik sevkıyat, suyun Dünya yanından üzerinde ve altında sürekli hareketini kullananlar. Suyun okyanus ve denizlerdene, atmosferden ve tekrar deniz-usa atmosfer genel olarak bu başarıyı verir. Evrenin kanunu, dünyaki korunumu şehirz ifade eden, başı ve sonu olmayan bir terimdir.

WATER RESOURCES IN THE WORLD: Oceans, seas, lakes, streams, waters and glaciers. The waters on earth are in it for a long time. The world is in a balanced way. When growing in rainy waters; Water resources with more precipitation and less evaporation increase. The World's Freshest Water Lakes account for 87% of the water in freshwater. – The waters of a lake can be brackish, fresh, soda or salty. For this; • The lake is not in the toilet. • The characteristics of the land where the lake is located • The climate characteristics of the place where the lake is located • The condition of the lake.

While the world population is increasing day by day, fresh water resources are getting more polluted. For this reason, it is very important to protect clean fresh water resources not only for ourselves, but also for future generations and other living things. In order to raise awareness on this issue, 22 March is celebrated as World Water Day every year by the United Nations. We can also reduce our own water footprint by paying attention to the most efficient use of water.

Reasons for the decrease in the quality of potable water resources (Ahsen Nidam -Nazire Seyhan/Ağrı Bilsem)

Water quality:

1. Leakage from underground storage tanks

2. Agricultural currents

3. Unsuitable industrial applications

4. Mining Operations

5. Injection of waste chemicals underground

6. It can be greatly affected by corrosive water. Applications related to the treatment of drinking water can also be a direct cause of water pollution.

Industrial sources of water pollution are pulp mills, chemical

manufacturing factories, steel mills, textile manufacturers, food establishments.

Among the sources of urban water pollution, public sewage treatment units are the most important. In particular, water without treatment and processing of waste sludge

Accumulating or spreading close to sources can be one of the most important sources of pollution.

Combined sewer systems that carry rain water and sewage together can cause contamination of water resources with surface leaks, especially in flood.

situations.

Agricultural areas, manure, planting and grazing areas are the main agricultural

are the causes of pollution.

Construction of forest roads, road construction, forest management, forest cutting etc. applications can be counted as silvicultural.

The construction sector, especially highway construction, soil development works, etc.

may be polluting.

In mining applications, all kinds of mines, oil drillings, ore accumulation areas and their associated leaks are polluting.

trestle tank leaks; Landfill areas, hazardous waste disposal areas can be important pollution elements.

Finally, all water interventions, trenching, bird opening, dam construction, current bank interventions can cause water pollution.

What is water pullition?

Water pollution; is the general name given to pollution seen in water-containing basins such as lakes, rivers, oceans, seas and groundwater. All kinds of water pollution damages all living creatures around or within the basin where the pollution is found, as well as setting the environment for the destruction of various species and biological communities. Water pollution occurs when wastewater containing harmful components is discharged into basins without adequate treatment.

Different Types of Water Pollution?

The most common type of water pollution, chemicals can infiltrate both underground water sources and those sitting on the Earth’s surface. As an integral component of the agricultural industry, it’s unsurprising that much of chemical contamination comes from the pesticides and fungicides used in farming, but metals and solvents from industrial sites are also leading contributors.

Unlike most others on this list, microbiological pollution is a naturally occurring form of water contamination. Microorganisms such as bacteria, protozoa and viruses can infiltrate water supplies, causing diseases such as bilharzia and cholera. Humans are most susceptible to this kind of pollution in places where adequate water treatment systems are not yet in place.

3. Nutrient pollution

While they’re vital for underwater flora and fauna to flourish, an excess of nutrients can upset the delicate imbalance of water-based ecosystems. Fertilisers contain a high concentration of nutrients which, if they contaminate rivers, lakes and coastal areas, can cause algal blooming that can block out sunlight and inhibit the growth of other organisms.

4.Oxygen-depletion pollution

Another consequence of algal blooms is their consumption of oxygen supplies. This means that those species which depend upon oxygen to survive are killed off, while anaerobic ones thrive. Some anaerobic microorganisms are capable of producing ammonia, sulphides and other harmful toxins, which can make the water even more dangerous to animals (and humans, too).

5.Surface water pollution

Referring to all water sources above ground, such as rivers, lakes, seas and oceans, surface water pollution can occur both naturally, accidentally and intentionally. For example, monitoring has an all-important role in natural flood management, which can lead to poor water quality, while accidental oil spills and negligent industries emptying waste into water bodies are also key contributors.

Global water consumption is increasing day by day. In addition, the change in climate due to global warming, the frequency of extreme weather events and the pollution of clean water resources cause the gradual depletion of clean fresh water resources.
