The types and concentrations of natural contaminates depend on the nature of the geological materials through which the groundwater flows and quality of the recharge water. Of course it depends on individual susceptibility and mode of contact with the body. Higher levels of contaminants in drinking water are seldom to cause acute health effects. These may be geological or anthropogenic (man-made) (Fawell and Nieuwenhuijsen 2003). Water contamination is a common problem to all over the world. Continued research efforts in this area for more than few decades result in many processes/technologies (Shannon et al. Providing safe water for all is a challenging task. Contaminated water causes problems to health and leads to waterborne diseases which can be prevented by taking measures even at the household level. It is seen that developed countries suffer most from chemical discharge problems, whereas developing countries from agricultural sources. One-sixth of the world population suffers from the freshwater unavailability situation (Elimelech 2006). With the advancement of technology and industrial growth, fresh water resources all over the world are threatened. It is a well-known fact that fresh water is an important necessity for our health. Ironically, sometimes, natural or added contaminations rob us of the gift and making us confront a lot more challenging world. The adequate supplies of water are necessary for agriculture, human consumption, industry as well as recreation. Availability of fresh water, the nature's gift controls the major part of the world economy.
