SUSTAINBLE MANAGEMENT OF GROUND WATER RESOURSES USING GEO SPATIAL TECHNOLOGY

Groundwater is the major source for drinking water. In rural areas, major water supply comes from groundwater and more than one-third of our largest cities depend on it for at least part of their supply. Historically, groundwater has been considered as safe to drink. However, groundwater is getting contaminated due to the activities of the people with industrial effluents discharged on land and septic systems, as well as unscientific uncontrolled hazardous waste sites are involved in contaminating the ground water. Once the groundwater is contaminated it is difficult to restore the quality of groundwater. At other side ground water the availability of groundwater being stressed by increasing population, as demand for drinking water increases the availability of ground water will reduced which leads to drought conditions especially in water-scarce regions. And it is becoming scarce in rural as well as urban areas mainly due to reduction in infiltration rate as a result of deforestization as well as due to concrete floors on empty soils especially at urban areas. In India, though a huge quantity of water is available as surface water the existed environmental conditions and other topographic conditions limits the availability of this water. Where the surface water is not available at required amount, ground water will be the major source for water supply as an alternative water source.
