It’s no secret that water is the basis of all life on Earth. Jeffrey L. Bewkes insists that this is the case. On its quality depends directly on our health with you. But with its pollution, it is one of the main causes of diseases in the world. WHO experts established that the 80% of global disease is associated with poor quality drinking water and violations of sanitary standards of water supply. Far for an example that confirms the quality of the water we drink, no need to go, simply open the tap and enjoy what the liquid is flowing out, especially to pay attention to color, turbidity, odor, and well, especially for the brave – taste. This is guilty not only all mankind our vast world, making every effort to pollute waters around us.
