AbstractIn the present paper groundwater potential is analyzed with the help of aquifer parameters like transmissivity, storage coefficient etc. The pumping test is conducted in gajulamalkapuram village which comes under. the musi basin. The demand of ground water is increasing in the study area caused deploiting of water levels below the ground. The pumping test is conducted for exisiting bore wells in agricultural fields of gajulamalkapuram. The test are conducted for 120 minutes with constant rate of pumping in single well (i.e., the pumping and drawdown is observed in the same well) The collected data was analysed by using theis and cooper and Jacob methods. from the results of pumping data, it is observed that the aquifer showing the high draw down rate due to the presence of lineaments or the structural displacements. the aquifer exhibiting the low transmissivity with moderate yield. This is due to the lack of secondary porosity, compaction of litho units and a shallower weathered layer. The Poor groundwater potential is the result of the over-exploitation of groundwater through the drilling of deeper bore wells.
