| Abstract | Groundwater is the primary source of drinking water for Kabul city residents, and it is also widely utilized for industrial and agricultural purposes. Identification of the major hydrogeochemical processes is significantly important for sustainable groundwater management in Western Kabul Plain (WKP) aquifer. In this research, the physicochemical results and isotopic ratios of water-stable isotopes of 13 groundwater and river water samples from the WKP were collected in April 2021 and employed to assess the hydrogeochemical processes using multivariate statistics and self-organizing map (SOM). The results of this study indicated that Ca–(Mg–Na)–HCO3 is the dominant type of hydro-chemical facies in the WKP aquifer. The findings revealed that all water samples originated from modern meteoric precipitation and the aquifer is mainly recharged from Kabul and Paghman rivers. The sampling locations were divided into three clusters based on Q-mode hierarchical cluster analysis and SOM models. The factor analysis and SOM models indicated that groundwater chemistry in the WKP aquifer is primarily controlled by the dissolution of calcite, dolomite, gypsum, halite, weathering of silicates, and ion exchange. The factor analysis and SOM models showed that NO3̄ concentrations principally originated from anthropogenic activities. The findings of this research may contribute to sustainable groundwater resource management in Kabul city. |
