Background: Groundwater contamination may be localized or spread over a large area, depending on the nature and source of the pollutant and on the nature of the groundwater system. A problem of growing concern is the cumulative impact of contamination of a regional aquifer from nonpoint sources and point sources. For the regional level investigation, geoelectrical methods are emerging advance technological supports to identify the contamination hotspot in groundwater. The geoelectrical methods integrated with the sediments chemistry and hydrogeological conditions can be used to investigate groundwater and vadose zone contamination investigation. Objective: The aim of this study is to investigate the aquifer contamination hotspot using advance geophysical techniques. Materials and Methods: In this study we have performed three level of sounding in study area at different geophysical level. The resistivity meter was installed at different AB/2 values to measure the resistivity of the geological formation using different sounding configuration. Parallel to sounding, the hydro-geological parameters were investigated and plotted in same scale. The measured resistivity of all three sounding was applied to hydro-geological formation to prepare the vulnerability maps. Results: The results of this study indicated the different level of the contamination in study aquifer and present in the vulnerability maps. The extension of the contamination was also indicated in the prepared vulnerability map to identify the area or zone of contamination hotspots. Conclusions: The investigation gives the understanding of the aquifer configuration at regional levels as well as the hotspots of contamination. On the basis of aquifer configuration and contamination level, the management’s strategy of the groundwater development and managements becomes the cost effective and more efficient technological supports to sustainable developments of water resources.
