“…As shown in the last sub-section, the EWQI is calculated using several physical and chemical parameters. More importantly, these parameters are inter-correlated, particularly the correlations that existed between the cations and anions associated with dissolved matter in groundwater due to various hydro-geochemical facies such as Na-Cl, Na-Mg-Ca-Cl, and Ca-Mg-HCO3-Cl [14] . Therefore, the generation of virtual datasets requires the conservation of the relationships that exist between the chemical parameters, so that the virtual generated data keeps the reel physical information that existed in the original dataset.…”

“…4) The Cenomanian, predominantly made up of dolomitic limestone and yellow marl, with green marl intercalated across a thickness of roughly 120 m (Ruhard 1975); Pliocene that set the Berrechid aquifer system made up of sandstone, sand, sandy limestone, and small conglomerates with a total thickness of 5 to 40 m (Droubi et al 2008); 6) Quaternary: The dominating facies is characterized by silts and conglomerates, which are followed by red silty clays, pebbles, and gravels with thicknesses varying from 0 to 50 m. As far as water quality is concerned, this water table is classified into three hydro-geochemical facies (Na-Cl; Na-Mg-Ca-Cl; Ca-Mg-HCO 3 -Cl). This region is marked by fertile soils and productive water tables, which causes the depletion of the water tables and the degradation of water quality, the latter becoming non-compliant with the consumption standard (El Ghali et al, 2020). Farmers mainly consume water for market gardening and livestock (Ouassissou et al, 2019).…”

In order to provide a recommendation on the quality of groundwater in the region of Berrechid, Morocco, we analysed the concentration of conductivity as one of the main measures to identify the salinity of the water. We applied artificial intelligence models for predicting the conductivity of water while analysing several physical parameters as input parameters of the models. To achieve this purpose, we exploited and evaluated the Random Forest (RF), Support Vector Regression (SVR), and k-nearest neighbour models using 400 data samples related to ten groundwater quality parameters in the Berrechid aquifer, Morocco. The results revealed that the overall prediction performance of the RF models is higher than the SVR and KNN models. Overall, the developed models are able to predict conductivity with high accuracy. The approaches developed in this study are promising for real-time and low-cost prediction of groundwater quality by using physical parameters as input variables.

Clay aquitards are semipermeable membranes that allow groundwater flow while retarding solute migration has been researched extensively but also subjected to much debate. At present, there is no evidence of whether the physical and chemical properties of clay soil and the isotopic composition of pore water affect the semipermeable membrane effect. In this study, we collected clay samples from drilling cores (30-90 m) in the Hengshui area located in the North China Plain (NCP), then extracted pore water using a high-pressure squeezing device. Vertical hydrochemical and isotopic profile variation trends for the pore water were revealed using hydrochemical (Cl À , Na + , Ca 2+ , K + , Mg 2+ , and SO 4 2À ) and stable isotopic measurements of H, O and Cl. The results showed that the hydrochemical clay interlayer pore water of the saline aquifer is Cl/SO 4 -Na/Mg type and the average total dissolved solids (TDS) are 10.17 g/L. However, the hydrochemical clay aquitard pore water is
