“…The analysis results show that the Fcontent fluctuates in an expansive range from 0.05 to 24.88 mg/L with an average level of 12.47 mg/L (of which 58% samples >1 mg/L). According to [45], the Fcontent in seawater ranges from 0.86 to 1.4 mg/L. Therefore, some samples reaching this threshold may be of marine origin.…”

Shallow aquifers in the Thanh Phu coastal area in Ben Tre Province are increasingly withdrawn for domestic and irrigation purposes. However, groundwater resources here are declining in quality due to the effects of seawater intrusion and anthropogenic activities. It requires an understanding of the groundwater origin and changes in water quality to protect local groundwater resources. By applying the hydrogeochemical approach, the origin and quality of groundwater here have been clarified. A total of 35 water samples were collected during the 2023 dry season. The laboratory analysis included 16 ions. The results show that the groundwater water types are Ca-Cl, Ca-Mg-Cl and Na-Cl, with the domination of the third pattern. Hydrochemical characteristics have shown evaporation, silicate weathering, cation exchange and marine effects as the vital processes governing the mineralization of regional groundwater. Most of the water samples are of poor quality, not adapting to domestic water standards according to the National Technical Regulation on Domestic Water Quality and WHO 2011. It requires water treatment before being used for domestic purposes. However, the SAR, Na%, PI, KR and EC values displayed that groundwater here was still acceptable for irrigation purposes, demonstrating the prospect of using groundwater for agricultural purposes in the study area.

“…However, it is increasingly vulnerable to pressures related to population growth, urbanization, and land cover changes (Sahadevan＆Pandey, 2023; Yuan et al, 2023). This is particularly true in arid and semi-arid areas owing to paucity of surface waters (Ouhamdouch, 2023). In the Pongo area of Peru, which has a tropical desert climate, the average annual precipitation is less than 100 mm, while the average annual evaporation is 2075.2 mm (2016-2019).…”

Understanding the hydrochemical characteristics and formation processes of groundwater in mining areas is crucial for protecting and utilizing underground water resources. This study analyzed 42 groundwater samples from the Pongo mining area in Peru to determine the spatial-temporal distribution patterns and formation processes of chemical components. Statistical analysis, Gibbs diagrams, ion ratios, and hydrogeochemical modeling techniques were used. The results show that the groundwater in the study area is weakly alkaline (pH = 7.72) and has a total dissolved solids (TDS) range of 253.19 to 17912.82 mg/L, with an average of 2788.31 mg/L. About 55% of the groundwater samples are classified as brackish or saline water. According to the Gibbs diagram, the chemical composition of groundwater is mainly controlled by evaporation and rock weathering. Furthermore, ion ratios indicate the contribution of human activities, oxidation of pyrite, and desulfurization reactions to ionic concentrations in this groundwater system. The dissolution of evaporite minerals such as halite and gypsum contributes to the presence of Na+, Cl−, and SO42−, while Ca2+ and Mg2+ mainly come from the dissolution of minerals like calcite, gypsum, dolomite, and silicate. It is worth noting that approximately 38% groundwater samples have recorded NO3− concentrations levels surpassing the standard limit of 10 mg/L for drinking purpose, which is mainly attributed to agricultural activities. Moreover, the hydrogeochemical modeling indicates a strong dissolution tendency for halite and propensity for dissolution for gypsum, calcite, and dolomite. Additionally, pyrite oxidation and cation exchange processes also occur.

“…In Morocco, several studies have been carried out on seawater intrusion in GW [62][63][64][65][66], while other studies have been carried out on assessment of GW quality and recharge mechanisms [67], and prediction of the WQI for the GW with multi-layer perceptron approaches [68]. However, few studies have been carried out on GW-SW interaction models [69].…”

The processed discharges from Tangier Automotive City’s (TAC) Chrafate Wastewater Treatment Plant (WWTP) contaminate the Jouamaa Hakama groundwater and the Ouljat Echatt river. We aimed to study the unknown interactions between surface water (SW) and groundwater (GW). A total of nine Jouamaa Hakama GW samples and eleven Ouljat Echatt SW samples were taken and analyzed in 2021 and 2022 to determine 16 physical and chemical parameters (pH, temperature (T), electrical conductivity (EC), dissolved oxygen (DO), total hardness (TH), turbidity (TURB), and total dissolved solids (TDS), cations: Na+, K+, Mg2+ and Ca2+, anions: Cl−, CO32−, HCO3−, NO3−, and SO42−). For exploitation of the data, we used a methodology based on hydrochemical modeling (HM), principal component analysis (PCA), Water Quality Index (WQI), Irrigation Water Quality Index (IWQI), inverse distance weighted interpolation (IDW) using Geographic Information Systems (GIS), and regression analysis (RA). We studied the interaction of the surface water of the river (contaminated by discharges from the WWTP) with the shallow groundwater on a strip of 100 m on either side of the river to understand the transverse and longitudinal dispersion of this pollution The investigations indicated that the major ions found in GW and SW were characterized in a different order in the anion list order Cl− > CO32− > NO3− > HCO3− > SO42− and Cl− > SO42− > CO32− > NO3− > HCO3−, respectively, while the concentrations of cations showed the same order for both: Na+ > Ca2+ > Mg2+ > K+. As a result, GW showed in the Piper diagram the type of sodium chloride to magnesium carbonate, while SW belongs to the sodium chloride to magnesium sulfate type. The WQI showed that the river waters are all unsuitable for use (WQI > 100), while the GW is of poor quality (WQI > 76). Moreover, the results of the GW–SW interaction along the river revealed a significant relationship (R² = 0.85), which means that strong circulation and the infiltration of contaminated SW into shallow GW occur in this area. The approaches followed have been proven effective in evaluating water quality for human and animal uses. These results can help decision-makers in the region take suitable management measures to mitigate this environmental problem.
