The word water is life, so life on this planet cannot be possible without water. Water is an essential natural resource that is a surface and groundwater device for human society. The purpose of this research is to assess the groundwater potentiality of the Purba Bardhaman district. All data (primary and secondary) are collected from different sources and analyzed in geographic information system (GIS) software to prepare thematic maps. Different geo-environmental factors like as land use and land cover, soil, lithology, rainfall and distance from the river, etc., can impact on groundwater availability directly or indirectly in Purba Bardhaman area. To identify groundwater potential zones, all these factors are composed into GIS software using multi-criteria decision analysis (MCDA) method. The groundwater potential map has been divided into five classes based on their magnitude as very high, high, medium, low and very low groundwater potential zones. It shows that the areas of very low, low, medium, high and very high groundwater potential zones are 21.54%, 35.80%, 26.47%, 10.13%, 6.06%, respectively, of the total area. Finally, validation is carried out using groundwater depth data collected from 44 drilled tube wells which are located in a scattered manner for whole Purba Bardhaman district which indicates a higher similarity with an area under curve value of 86.8%.

水是生命，所以没有水就不可能在这个星球上生存。水是必不可少的自然资源，是人类社会的地表和地下水设备。这项研究的目的是评估Purba Bardhaman地区的地下水潜力。所有数据（主要和次要）均从不同来源收集，并在地理信息系统（GIS）软件中进行分析以准备专题图。不同的地球环境因素，例如土地利用和土地覆盖，土壤，岩性，降雨以及与河流的距离等，都可能直接或间接影响Purba Bardhaman地区的地下水供应。为了确定地下水的潜在区域，使用多标准决策分析（MCDA）方法将所有这些因素组合到GIS软件中。地下水位图根据其高，高，中，低和非常低的地下水位区的大小分为五类。结果表明，地下水位极低，低，中，高和极高的区域分别占总面积的21.54％，35.80％，26.47％，10.13％和6.06％。最后，使用从44个钻探管井中收集的地下水深度数据进行验证，这些数据以散布的方式分布在整个Purba Bardhaman地区，表明与曲线下面积的86.8％相似。总面积的 最后，使用从44个钻探管井中收集的地下水深度数据进行验证，这些数据以散布的方式分布在整个Purba Bardhaman地区，表明与曲线下面积的86.8％相似。总面积的 最后，使用从44个钻探管井中收集的地下水深度数据进行验证，这些数据以散布的方式分布在整个Purba Bardhaman地区，表明与曲线下面积的86.8％相似。
