Aquifer Mapping studies and Management Plan has been carried out in South West Khasi Hills district, Meghalaya under National Aquifer Mapping and Management Plan (NAQUIM) programme 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 has been done through multi-disciplinary approach so as to achieve the said objectives. Out of the total area of 1401 sq.km of the district, the total coverage area of aquifer mapping and management plan is 609 sq.km, which is underlain by consolidated rocks of Granite, Gneiss, Sandstone and Limestone. Occurrence of ground water in the study area is mainly of weathered and fractured Granite, Gneiss, Sandstone and Limestone. Being a hard rock terrain, the aquifer system in this district can be divided as 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 or shallow bore wells. The second aquifer is the deeper aquifer which tapped the fractured zone.
