Hydrogeochemical Studies of Groundwater

Water is a non-renewable and most precious resource. Groundwater occupies a major part in water supply for drinking, irrigation and industrial purposes in the world. In India arid and semiarid regions, especially in rural regions, most population depends on the groundwater for their drinking and irrigation purposes. It is evaluated that nearly one third of the world's population depends on groundwater for drinking purpose. Drinking water is an important resource that needs to be protected from pollution and biological contamination. Water is vital to health, well-being, food security and socioeconomic development of mankind. Underground water is clean but it depends upon quality and quantity of minerals dispersed and dissolved in it. Therefore, the presence of contaminants in natural fresh water continues to be one of the most important environmental issues in many areas of the world, particularly in developing countries where several communities are far away from potable water supply.
