Aquifer Mapping studies and Management Plan has been carried out in West Garo 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. This study has been done through multi-disciplinary approach so as to achieve the said objectives. The total coverage area of aquifer mapping and management plan is 1830 sq.km out of 2811 sq.km of the district and is underlain by unconsolidated rock (alluvium), semi consolidated rocks (sandstone and shale) and consolidated rocks (granite gneiss). Geomorphologically, the district represents a remnant of an ancient plateau of Precambrian Indian shield block, uplifted to its present height due to tectonic activities in the past. The southern and northern parts form a platform on which Tertiaries were deposited in the post- cretaceous period. Agriculture is the main stays of livelihood of the people in the district. The importance of agriculture in the life of the people is reflected in the population which is predominantly rural. The main crop being paddy, the other crops cultivated in the district are mustard, sugarcane, jute, potato, tapioca, cotton etc. Major part of the district is covered with hill and communication is poor. As such habitation is clustered in plain area and ground water abstraction structures are also clustered in the plain area. Occurrence of ground water in the study area is mainly of weathered and fractured Gneissic rocks, fractured Sandstone and granular zone of alluvium formation. 35 key dug wells and 7 nos. of springs are established to study the water level, quality, spring discharge and its behavior periodically. Besides there are 14 ground water monitoring station in the district and 8 Exploratory well and 4 observatory well (drilled during the AAP) were monitored throughout the year. Moreover, water samples were collected from monitoring wells for detailed, iron, heavy metals and arsenic.
