Sources of water pollution

Water is an essential element is very important for human and animal and plant life, where fuel, which can not do without it, Vlmejrd Alastaina her briefly disrupted vital functions in the body of organisms, and not to drink for a long time lead to death as a result of an imbalance and disorders in the limbs. The variety of water sources around the world, and is distributed between the rainwater, groundwater, rivers and lakes, water wells, water and sea water and sea water and those used by some countries after the desalination process them. Due to the presence of water in one of the open and open to all the external factors spaces, making water susceptible to contamination by leakage of pollutants and toxic substances, waste and waste, thus wasting and make a non-resource use, leading to a decrease in useable quantities of water surface of the Earth. There are several sources of water pollution sources may be caused by natural factors such as high levels of life, leading to increased evaporation and thus increasing the salinity of water bodies, or impurities move from one place to another and stability within these organs. Or pollution that gets the water bodies be due to leakage of chemicals such as pesticides or insecticides waste plants oil or radioactive materials or waste water or waste or 

wastewater and many other contaminants Ooualemwad , so that these factors contribute to increase the proportion of the growth of harmful substances and bacteria and viruses in the water as it leads to organizations that rely on drinking this water, or organisms that live in the plans water such as fish and aquatic plants poisoning, pollution of water leads to a decrease in the proportion of the elements and gases necessary for the life of aquatic organisms such Kaloksgen, which is important to the process of breathing. Note that the man is responsible for all these factors, Femiah wastewater Almgayh freshwater lead to cause several serious diseases to humans and animals when they drink this water diseases such as cholera, schistosomiasis, and various infections, diarrhea and vomiting, malaria and salmonella. The spill of pesticides in water leads to cancer, asthma, allergies, birth defects and fetal diseases of the stomach, while oil spills in water mainly leads to cancers and reduce amount of aquatic organisms. And these are the ways to reduce and prevent pollution of various kinds of water for several states to take Ktnqah procedures and wastewater treatment and disposal of radioactive materials in appropriate ways to the environment, and Mills control and industrial waste, and community awareness of the need to maintain the supply of clean, pure water for the sustainable use of all living organisms and creatures.
