Water is essential for the life of both plants and animals. If we take in consideration only 3% of water is fresh water between which most of it frozen. As a matter of fact, groundwater is a key source of freshwater, providing nearly half of the world's drinking water. Groundwater is invisible source of water with visible result in life of human being. We are using groundwater like an advantage because of its unparalleled quality and availability, and now we all have groundwater management challenges across the globe.
