Ground Water Pollution

The purpose of this paper is to describe and analysis of ground water pollution. When many people think of a water source, they think of lakes, rivers and streams; in other words, surface water.  However, of all of the usable freshwater in the world, approximately 97 percent of it is groundwater. Scientists agree that there is a lot of water under the earth’s surface! The crucial role groundwater plays as a decentralized source of drinking water for millions rural and urban families cannot be overstated. According to some estimates, it accounts for nearly 80 per cent of the rural domestic water needs, and 50 per cent of the urban water needs in India. Groundwater is generally less susceptible to contamination and pollution when compared to surface water bodies. Also, the natural impurities in rainwater, which replenishes groundwater systems, get removed while infiltrating through soil strata. But, In India, where groundwater is used intensively for irrigation and industrial purposes, a variety of land and water-based human activities are causing pollution of this precious resource.
