Aquifer Mapping studies and Management Plan has been carried out in East 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. The total coverage area (mapable area of the district) of aquifer mapping and management plan is 1053 sq.km, out of 2748 sq.km of the district. The area is underlain by consolidated rocks of Archaean Gneissic complex, Granite pluton, limestone, Quartzite and Phyllites (Shillong Group), with narrow belt of dolerite and ultrabasic sills and dykes from khasi green stone belt with limited areal extent in North-Central part. Small patches of conglomerate and sandstone from Khasi Group of rocks are also found in south western part of the district. Occurrence of ground water in the study area is mainly in weathered and fractured Gneissic, Granite pluton Quartzite formation and to a very less extent in dolerite dykes and sills at some places. The different hydrogeological data are generated through intensive field data collection and testing.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 residum where ground water occurs under water table condition and is mainly developed through construction of dug wells. The second aquifer is the deeper aquifer which tapped the fractured zone and is mainly developed through boring and construction of tubewells Based on the study of litholog and analysis of depth of construction of dug wells and bore wells, it is found that the first aquifer occur within 2 to 35 m bgl. Ground water in the second aquifer occurs under semi-confined to confined condition in the fractures upto the maximum explored depth of 247.6 m bgl.
