Water Availability and Water Quality
Water is the most precious natural resource that exists on our planet. Every living thing needs water in order to survive.

Water availability has become a great concern in our world today. Out of all the available water on earth, only 3 % of it is fresh water. 77% of this fresh water is frozen which basically means that there is a very limited amount of water that is available for usage. The pollution of water isn’t the only problem that limits its availability. As we know, it takes a certain amount of time for the water to go through the cycle in order to be reused. Of course many people might think that there is always groundwater as a last resource but they don’t realize that it takes thousands of years for aquifers to form and they must drill down really deep into the ground to get water. Water availability isn’t the only problem. Water quality has also become a big issue. The amount of clean water that is available has decreased within the past decade. Although some types of water pollution occur through natural processes, most of the pollution is caused by human activities. The water we use is taken from rivers, lakes and underground, and these are the same places the water returns to after we have finished using it – or actually, not finished using it but finished contaminating it. Water pollutants categorizes into four basic categories: pathogens and other organic materials, chemicals including organic and inorganic toxic substances, thermal heat, and suspended materials. Organic materials such as pesticides, fertilizers, plastics, detergents, gasoline, oil, factory waste water, and fossil fuels are among the most severe pollutants. In order to prevent water pollution, we have to remove the pollutants before the water rejoins the...
