Aquifer Mapping Studies and Management Plan has been carried out in South Garo Hills district, Meghalaya under National Aquifer Mapping and Management Plan (NAQUIM) program with an objective to know the different aquifer system prevailing in the study area, to decipher the vertical and lateral extend of the aquifer down to the depth of 200 m, its characteristic, quantity as well as quality so as to bring a complete sustainable and effective aquifer management plan for ground water resources development in the study area. These studies have been done through multi-disciplinary approach so as to achieve the said objectives. The total coverage area of aquifer mapping and management plan is 868 sq.km out of 1887 sq.km of the district and is underlain by consolidated rock of Gneiss and semi consolidated rock of Sandstone. Ground water occurs in the study area mainly in weathered and fractured sandstone and gneiss. The different hydrogeological data are generated through intensive field data collection and testing. The aquifers present in the district can be divided into a two aquifer system viz., first aquifer (shallow) and second aquifer (deeper). Shallow or first aquifer consists of weathered residuum where ground water occurs under water table condition and is mainly developed by construction of dug wells, shallow bore wells or hand pump. The second aquifer is the deeper aquifer constitute of fractured zones. Based on the study of litholog and analysis of depth of construction of dug wells and shallow bore wells, it is found that the first aquifer occurs within 2 to 30 m bgl. Ground water in the second aquifer occurs under semi-confined condition in the fractures zone upto the maximum depth of 142 m bgl.
