“…Tese results are similar to those found in the study by Bouteraa and colleagues who showed that groundwater quality is infuenced by geochemical processes (water-rock interaction) and human practices (irrigation) [20]. In addition, the study conducted in the Zinder region of Niger revealed that there are two mechanisms responsible for water mineralization which are soil rainfall and residence time in the aquifer [9]. On the other hand, the distribution of nineteen physicochemical and bacteriological parameters using varimax rotation on the factorial planes (Factor 1-Factor 2), (Factor 1-Factor 3), and (Factor 1-Factor 4) showed that all factors except Factor 1 showed contamination by nitrates which are mainly due to anthropogenic action and are introduced into the subsoil, either by leaching of applied fertilizers or by wastewater discharge.…”

“…Generally, the factorial designs (F1-F2), (F1-F3), and (F1-F4), show a negative correlation with the parameters Fe 2+ , TC and K + . Tis could be due to the heterogeneity of the waters of these aquifers and the low values of these ions recorded, as according to the work of Souley Moussa et al in 2019 [9], out of the nineteen parameters he studied, fve of them do not participate in the constitution of the factorial axes. Similarly, the distribution of physicochemical and bacteriological parameters on the factorial planes (F1-F2), (F1-F3), and (F1-F4) allowed the identifcation of the phenomena at the origin of the mineralization of these groundwater, which are related to soil rainfall and residence time in the aquifer, as well as to agricultural pollution due to the use of nitrogenous fertilizers, and to water-rock contact.…”

“…Unfortunately, the presence of public dumps near these water resources increases the risk of pollution and transmission of vector-borne diseases and threatens human and environmental health [7,8]. Hence, the need for physicochemical and bacteriological analyses, which constitute a reliable source of information to characterize the impact of human, agricultural, and industrial activities and of the diferent landscape units, as well as the origin of mineralization [9]. Indeed, the presence of Na + , K + , and HCO 3 − refects the nature of the minerals encountered during infltration and the nature of the rocks crossed, for the high contents of Cl − , and SO 4 2− indicate leachate wastewater, and the high content of NO 3…”

Groundwater is a vital resource and a development lever for many countries, including Morocco. To develop these resources, mineralogical and hydrogeochemical studies as well as a bacteriological study were carried out on the groundwater of the Angads aquifer, which is located in the northeast of Morocco to highlight the processes at the origin of mineralization, their quality for human consumption and irrigation, as well as the hydrogeochemical facies of these waters. To do this, a multivariate statistical analysis using principal component analysis, varimax rotation of factors, and hierarchical ascending classification were conducted for all the groundwater samples of the Angads aquifer in Oujda. The main results revealed that these waters present faecal contamination by faecal and total coliforms and faecal streptococci. And another one by nitrates due to the high values of NO3−, as well as the mineralization of these waters is controlled by the nature of the geological formations crossed and the residence time in the aquifer, which is confirmed by the presence of ions such as Cond, HCO3−, Ca2+, Mg2+, and SO42−. Concerning the quality of the groundwater, according to Moroccan standards and the World Health Organization, the results show that they are generally unsuitable for human consumption and irrigation. Two diagrams were used to study the facies: Piper and Schoeller–Berkaloff. The results show that these waters are highly mineralized, with the chloride and sulphate calcic and magnesian facies dominating with 89.47%. To protect this vital resource, sustainable management actions must be implemented, in particular, to reduce the use of pesticides, control the use of fertilizers, and clean up and purify the groundwater.

“…The Zeroud groundwater samples had pH values ranging from 6.7 to 7.73, with an average of 7.286, suggesting that the water samples were slightly alkaline and fell within the pH range of (6.5-8.4) recommended for irrigation purposes [89]. These slightly neutral to alkaline values of pH were probably due to the alteration of feldspars and some carbonated minerals [90]. The electrical conductivity (EC) values in the groundwater samples varied significantly from 1514.7 to 5185.9 µS.cm −1 .…”

In the Zeroud basin, a diverse array of methodologies were employed to assess, simulate, and predict the quality of groundwater intended for irrigation. These methodologies included the irrigation water quality indices (IWQIs); intricate statistical analysis involving multiple variables, supported with GIS techniques; an artificial neural network (ANN) model; and an XGBoost regression model. Extensive physicochemical examinations were performed on groundwater samples to elucidate their compositional attributes. The results showed that the abundance order of ions was Na+ > Ca2+ > Mg2+ > K+ and SO42− > HCO3− > Cl−. The groundwater facies reflected Ca-Mg-SO4, Na-Cl, and mixed Ca-Mg-Cl/SO4 water types. A cluster analysis (CA) and principal component analysis (PCA), along with ionic ratios, detected three different water characteristics. The mechanisms controlling water chemistry revealed water–rock interaction, dolomite dissolution, evaporation, and ion exchange. The assessment of groundwater quality for agriculture with respect IWQIs, such as the irrigation water quality index (IWQI), sodium adsorption ratio (SAR), sodium percentage (Na%), soluble sodium percentage (SSP), potential salinity (PS), and residual sodium carbonate (RSC), revealed that the domination of the water samples was valuable for agriculture. However, the IWQI and PS fell between high-to-severe restrictions and injurious-to-unsatisfactory. The ANN and XGBoost regression models showed robust results for predicting IWQIs. For example, ANN-HyC-9 emerged as the most precise forecasting framework according to its outcomes, as it showcased the most robust link between prime attributes and IWQI. The nine attributes of this model hold immense significance in IWQI prediction. The R2 values for its training and testing data stood at 0.999 (RMSE = 0.375) and 0.823 (RMSE = 3.168), respectively. These findings indicate that XGB-HyC-3 emerged as the most accurate forecasting model, displaying a stronger connection between IWQI and its exceptional characteristics. When predicting IWQI, approximately three of the model’s attributes played a pivotal role. Notably, the model yielded R2 values of 0.999 (RMSE = 0.001) and 0.913 (RMSE = 2.217) for the training and testing datasets, respectively. Overall, these results offer significant details for decision-makers in managing water quality and can support the long-term use of water resources.

This work aims to analyze the quality of groundwater in the riparian areas of the bauxitic plateaus of N'Dangara and Boundou Wandé in operation by the CBG (Compagnie des Bauxites de Guinée). The geology of the study area consists mainly of sedimentary formations of the Devonian faro, Neogene and Quaternary. Three water measurement and sampling campaigns on the two plateaus were carried out with determination of piezometric measurements and physic-chemical parameters. This study showed that the general flow direction of groundwater is dispersed. The flows at Boundou Wandé are from the center of the plateau to the north and that at N'Dangara is from the center to the south and southwest. It can be seen that the direction of groundwater flow reflects overall the relief of the deposit conditioned by its geomorphological framework. It emerges from the analysis of physical and chemical parameters that well water is consumable. However, the water from wells MW15, MW16, MW17, MW18 and MW21 with a low pH (4.84 to 5.13) may present a certain nuisance for its consumption and because it can be corrosive. Analysis of the Piper diagram showed two hydrogeochemical facies (calcium and magnesium bicarbonate facies and sodium and potassium carbonate facies). However, this study strongly suggests continuous monitoring of groundwater in and around the study area in order to meet the demand for water supply to communities without compromising the ability of future generations to meet water quality requirements.
