Geology of any region refers to its history of sequential occurrence of rocks. It presents origin, nature and structure of rocks. Occurrence, nature and structure of rocks help to know about their water bearing properties. Generally, alluvium rocks mainly kankar and sand or bazari and sand denotes better water bearing properties of rocks due to its porosity, permeability and specific yield, which determine the capacity of rocks to hold and transmit water. Alluvium deposits consisting of medium to coarse grained sand are the main source of groundwater for tube wells of the study area. The water table depth and its recharge is controlled not only by climatic factors and relief but also by hydro-geological characteristics of rock formation. The water table stage fluctuates almost continually under the combined influence of a set of forces- causing recharge to or discharge from the groundwater reservoir. But this recharging and discharging properties depends upon nature and structure of rocks mainly on porosity, permeability, thickness and transmissibility of geologic formations. The hydro-geological studies indicate that near groundwater occurs under water table condition while deeper aquifer occurs under semi-confined conditions and water table stage reflects the quantity of groundwater in storage. The water bearing characteristics of a stratum is noted by borings. It is generally determined by on spot examination of the hydraulic pressure prevailing in the stratum by the level to which water rises in the boring tube. It is noted that in non-water bearing stratum, the water level in the tube is appreciably lower than the static level, while in a water bearing stratum, it either approximates to or is higher than the static level.
