Surface water is any body of water which is on the earth’s surface: lakes, rivers, streams, and reservoirs. About 75% of the earth is covered in water. Perlman, H. (2016, December 2). Although the levels of clean, potable water do not vary significantly year after year, climate change is currently changing the rules about how much potable water we'll have access to. Although surface water is an important source of drinkable water, surface water depends on several variable precipitation patterns, which makes it unreliable.

Potable water is essential for all life forms to thrive. There is no shortage of water on earth. Yes, hydraulic fracking, as a method of oil and gas production, has been performed since the early 1950s and has become much more widespread across the United States within the past decade.

Other illicit activities such as pirating and livestock raiding are seen as reasonable alternatives to the declining stability of animal herding (Factbook). Using membrane water treatment technology to make potable water means that we can still have a future in which all water needs are met, ecosystems are kept healthy and all living organisms stay healthy, even with climate changes. (2010, September). Because process of evaporation, condensation, and precipitation has essentially “distilled” the water, it is considered clean before it hits the ground.

Every day, water goes through a cycle that sees it flow from land, to the seas and then evaporates into the atmosphere through the processes of evaporation and precipitation. Rivers can obtain their water from two sources: base flow and runoff. hbspt.cta._relativeUrls=true;hbspt.cta.load(2373607, 'bf3ec425-0c53-4a1f-b883-2f16ddc9a496', {}); Topics: • Violence erupts in 1992 over a dispute between Uzbekistan and Turkmenistan regarding the contested Tyuyamuyun reservoir.

Glaciers and icecaps cover 10% of the worlds mass and exist primarily in Greenland and Antarctica. Can humans drink seawater? The groundwater emerges and feeds the streams and saturated wetlands. It is a common fact that the world is covered in water. Most of it flows through underground aquifers which can be accessed by digging wells; the rest are found in rivers and streams which we refer to as, surface water. Of the fresh water available on earth, only 31% is accessible for use. One could assume that water shortage shouldn't be much of a concern for humans when considering how much water is in the ocean, especially when 70% of the earth’s surface is covered in it (Bureau of Reclamation, 2017).

How Much Water is on and in the Earth. 70% of the earth is covered in water, yet only 3% of it is fresh. So, if only 31% of the fresh water is available for drinking, this means 31% of 2.5%=0.00775, which equates to less than 1%. About 3.6 million people die annually from diseases resulting from unsafe drinking water. I n order to calculate the percentage of drinkable water on earth, we’ll have to start large and "filter" our way through.. One could assume that water shortage shouldn't be much of a concern for humans when considering how much water is in the ocean, especially when 70% of the earth’s surface is covered in it (Bureau of Reclamation, 2017). The remaining 3% is fresh water. There are 263 rivers and countless aquifers worldwide which either cross or demarcate geopolitical boundaries.

They usually start as small creeks in the mountains, and then gradually merge with larger streams as they flow downward, eventually forming large rivers which empty out into the ocean. I'm Jeremiah Castelo, the owner of World Water Reserve. Oceans are the world’s largest source of surface water and makes up 97% of it, but due to its high salinity, it is unusable for humans (Postel, 2010). This lack of economic stability fuels recruitment appeal with militant groups such as Al Shabaab, which provide cash incentives and other benefits to their soldiers. Anything less that 100% is considered soil mixture. Condensation begins when the moisture from these gas molecules become so great that they fall back to earth in the form of precipitation.

Runoff is when the force of gravity naturally pulls water downhill from higher to lower altitudes. They’re either locked up in polar ice caps and glaciers, stored in the atmosphere or soil, are highly polluted, or are too far underneath the earth’s surface to be extracted.
