Water provides the earth with the capacity of supporting life. An organism does not have to be told how important water is to their existence. An amphibian knows to lay its eggs in water or else there will be no new born. Even flies know to lay their eggs in fresh water. The only organism that does not understand the importance of water is humans especially in industrialized countries.
Although water covers more than 70% of the Earth, only 1% of the earth’s water is available as a source of drinking. Yet our society continues to contaminate this precious resource.Water is known as a natural solvent. Before it reaches the consumer’s tap, it comes into contact with many different substances including organic and disease – producing contaminants that may be present in the water. Although disinfection is an important step in the treatment of potable water, they are used to prevent disease, can create byproducts which may pose significant health risks. Today, drinking water treatment at the point-of - use is no longer a luxury, it is a necessity.
