The present study highlights techniques for detecting and mapping prospective groundwater regions situated in West Bengal, India along the district of Purulia by implementing geospatial techniques. The region experiences an episodic shortage of water supply although it receives moderate rainfall, which challenges sustainable groundwater provision. Remote sensing, GIS, and geospatial techniques, namely the analytical hierarchy process (AHP) are implemented to determine the prospects of groundwater levels using geology, geomorphology, lineament density, drainage density, soil, slope, rainfall, elevation, and land use/land cover datasets. Applying the comprehensive methodology results in delineating and classifying the study area into five different groundwater potential zones ranging from very low to very high. The analyzed data shows that 37% of Purulia comprises low potential zones and only 5% of it has high potential zones. Such an alarming distribution of groundwater potential zoning (GPZ) can be attributed to its unique geomorphological and geological setting that consists of less porous rocks, undulating topography, and poor drainage. On the other hand, the higher potential areas are credited for their flood-prone plains, efficient groundwater management, and measures of conservation undertaken by the Government. The study delves into understanding, monitoring, and exploring the groundwater quality in the study area and helps in devising alternative sources in cases of shortages and crises using technically advanced measures. The techniques used in the study are relevant not only in terms of local specifications but can also be widely used to study similar areas that are experiencing similar challenges in terms of geographical characteristics.
