“…The elevated concentrations of metals (such as Pb 2+ , Cu 2+ , and Zn 2+ ) in the well waters, exceeding the established standards, are associated with natural processes resulting from water-rock interactions of geological origin. The pollution is linked to the contact of water with the Zn-Pb deposit in abandoned mining sites, and the release of these metals is facilitated by the erosion of volcanic rocks due to wind and precipitation (Nouayti et al, 2020). As indicated by Manaouch, Zouagui and Fenjiro (2020), water erosion significantly contributes to soil redistribution in the study area.…”

The current study aims to assess underground water pollution using an integrated approach that combines statistical methods such as principal component analysis (PCA) and water quality diagrams (Piper diagram, Schoeller– Berkalov diagram). A total of twenty water samples were collected from the Tiflet region in the Sebou basin and analysed for various physicochemical parameters, including temperature, pH, and heavy metal concentrations (Cu2+, Zn2+, Fe2+ and Pb2+). The average concentrations of Pb2+, Zn2+, Cu2+, and Fe2+ in the water samples were found to be 41.9, 14.8, 20.1, and 8.1 mg∙dm–3, respectively. These concentrations indicate a significant presence of heavy metals in the groundwater samples. Therefore, it can be concluded that the groundwater in this area is heavily polluted with heavy metals and other pollutants. This finding raises concerns regarding the use of this water for irrigation and agricultural activities in the region. This suggests that these four components play a crucial role in determining the overall water quality. The distribution patterns of the metals Pb2+, Zn2+, Cu2+, and Fe2+ in the well water within the study area are of particular environmental concern. It is recommended to establish a monitoring network to ensure the sustainable management of water resources in order to address this issue effectively.

“…Rock fractures increase permeability and secondary porosity, and correspondingly increase vertical water flow. For this reason, rock fractures (i.e., faults) were considered a critical factor and included in identifying areas of potential recharge (Nouayti et al, 2017). • Drainage density allows to draw essential conclusions about water runoff and infiltration.…”

“…From a hydrogeological point of view, the most important aspects are vegetation cover and impervious layers (Boukheir et al, 2008). • Topography plays a significant role in increasing surface water velocity, which subsequently reduces vertical infiltration and thus impacts recharge processes (Nouayti et al, 2017). The greater the slope, the greater the velocity of flow of surface water, and groundwater is less likely to accumulate.…”

Due to the rapid population increase in the Middle Seybouse sub-catchment area in North-East Algeria, the intense agricultural practices, and the industrial development, precious water resources proven to be significantly challenged in their sustainable exploitation both in terms of quantity and quality. The aim of this study is to identify the most suitable areas for groundwater recharge in the Middle Seybouse sub-catchment, over about 770.91 km², using remote sensing data and Geographical Information Systems (GIS). Six factors are recognized to positively affect groundwater recharge: rainfall, land cover, topography, drainage density, lineament density, and lithology. According to their level of involvement in the recharge process, these parameters have been reclassified and then evaluated using the multi-criteria analysis known as “Analytical Hierarchy Process” (AHP). A potential recharge map of the study area was produced showing that 60% of this area, located in the southern and central parts of the catchment, has a high to very high potential. ROC (receiver operating characteristic) curve is used to validate the resulting groundwater potential recharge map using the existing wells in the study area.
