The total volume of fresh groundwater stored on Earth is between 8 and 10 million km3 or 96% of non-frozen freshwater. Groundwater provides almost 50% of all drinking water worldwide and 43% of all consumptive use of water for irrigation in agriculture. Changes in groundwater availability and quality impact human health, livelihoods, food security and national economic development. Many aquatic ecosystems and their biodiversity depend on groundwater. Failure to manage groundwater sustainably puts at risk massive benefits for human well-being, sustainable development and biodiversity conservation. The long-term viability of irrigation-based economies in our country is threatened, creating long-term risks for global food security. Over-exploitation of groundwater and contamination threatens drinking water supply for hundreds of millions of people. Degradation of groundwater reduces resilience of communities and economies to climate change. However, due to rapid and uneven development, this resource has come under stress in several parts of the country. Central Ground Water Board (CGWB) is involved in Hydrogeological investigations; major part of the country has been covered. CGWB has also carried out ground water exploration in different phases with prime objective of demarcating and identifying the potential aquifers in different terrains for evaluating the aquifer parameters and also for developing them in future. The reports and maps generated from the studies are mostly based on administrative units such as districts and blocks and depict the subsurface disposition of aquifer on regional scale. Volumetric assessments of ground water and strategies for future development and management, these reports are available for most parts the country in different scale. However, due to paradigm shift in focus from development to management of ground water in last one decade, the need for more reliable and comprehensive aquifer maps on larger scale has been felt for equitable and sustainable management of the ground water resources at local scale.
