Vulnerability analysis in areas vulnerable to anthropogenic pollution has become a key element of sensible resource management and land use planning. This study is intended to estimate aquifer vulnerability using the DRASTIC model and using the vertical electrical sounding (VES) and electrical conductivity (EC) outcomes. The model allows for the identification of hydrogeological environments within the scope of the research, based on a composite definition of each environment’s main geological, geoelectrical, and hydrogeological factors. The results from the DRASTIC model were divided into four equal intervals, high, medium, low, and very low drastic index values. The SW area and NE area depict drastic index values from medium to very high, making it the most vulnerable zone in the study area, while the NW and SW areas show low to very low drastic index values. In addition, the results from the VES and EC the freshwater aquifer in the NE area and brackish water in the SE area, while the rest of the area falls into the category of brackish water. Overall, it can be concluded that areas having freshwater assemblages are on the verge of becoming contaminated in the future while the rest of the NW and SW areas constitute less vulnerable zones. The validation conducted for DRASTIC and EC shows a nearly positive correlation. Wastewater treatment policies must be developed throughout the studied region to prevent contamination of the remaining groundwater.

“…Figure 4 shows the final susceptibility map of the investigation region. The map is generated by combining the impact of all the seven considered factors in GIS [1]. Chitral is divided into five classes; very high, high, medium, low, and very low and the DRASTIC index ranges for these classes are 80-100, 100-120, 120-140, 140-160, and 160-180 in that order.…”

“…It is the only life support source proving substantial for cultivable lands and uncultivable, where there is no other water source available [4,5]. More than two billion people need drinking water and rely on groundwater [1]. However, in recent times, due to accelerated population increase, agriculture needs, and high manufacturing expectations, the quantity and quality of groundwater sources are failing across the globe [4,[6][7][8].…”

“…Around 60% of the world's total grain is irrigated and harvested by two-thirds of the freshwater, which is expressively contributed by groundwater. Statistics show that the extraction of groundwater globally is anticipated to be 750-800 billion cubic meters (BCM) annually for agriculture use [1]. Furthermore, the percentage is increasing by 1-3% yearly around the globe because of increasing population and high living demands [18].…”

Groundwater contamination along with anthropogenic actions and land use forms are increasing threats in urbanized zones around the world. Additionally, water quality and quantity are declining due to urbanization development. DRASTIC parameters (depth to the water table, net recharge, aquifer media, soil media, topography, impact of the vadose zone, hydraulic conductivity) were considered to investigate hydrological characteristics for assessment of contamination. Having a major effect of anthropogenic activities, various susceptibility zones were produced by modifying the DRASTIC model into DRASTICA, integrating anthropogenic effects as the “A” parameter in an alphabetic system. After the assessment, the research exposes that from the total area, 14% is under very high susceptibility, 44% is of high susceptibility, 39% is of moderate susceptibility, and 3% is of low susceptibility to groundwater pollution. The results in the built-up areas and based on the parameter of nitrate in quality of water show that the altered DRASTIC model or DRASTICA model proved to give better outcomes compared with the usual DRASTIC model. The policy advisers and management authorities must use the analysis data as precaution measures so that future calamities can be avoided.
