“…Similar correlations are observed between these parameters and TDS. In both cases, the correlation is positive and helps deduce the major elements responsible for the increase in mineralization and salinity in the studied waters (Bouselsal and Saibi, 2022; Bouselsal and Belksier, 2018; Hao et al, 2022).…”

“…The fundamental hydrochemical mechanisms influencing the mineralization of groundwater include ion exchange reactions with surrounding rocks, the dissolution of saline minerals, acid-base interactions, ion exchanges, and human activities. The chemical composition of groundwater is often analyzed using bivariate diagrams, based on the concentrations of compounds in meq/l (Hao et al, 2022;Kharroubi et al, 2022). The selection of these diagrams follows an examination of the lithological composition of the aquifer and the establishment of correlation links between the different chemical compounds present in the water.…”

In the semi-arid region of Ain Ouassera, Algeria, groundwater from the lower cretaceous aquifer (LC) serves as an essential resource for drinking and various other requirements. This study focuses on evaluating the suitability of water for domestic use and examining the non-carcinogenic health risks associated with consuming water containing high levels of nitrates. To explore these dimensions, the research utilizes the water quality index (WQI) method and the health risk assessment (HRA) model as formulated by the USEPA. The findings categorized the groundwater quality predominantly as "poor" for consumption purposes, with nitrate concentrations ranging from 14 to 112 mg/L, where 40% of the samples exceeded the World Health Organization's (WHO) permissible limit (> 50 mg/L). Furthermore, the health risk analysis indicated that 76.67% of the samples for children and 70% for adults surpass the safety thresholds (QH > 1), signifying a significant risk to the local population. The study also uncovered that the hydrochemical characteristics of the groundwater reflect a mixed composition (CaMgCl) and that mineralization is mainly attributed to the dissolution of carbonates, sulfates, and halite, alongside inverse ion exchange processes and anthropogenic influences. These findings underscore the urgent need for improved groundwater management measures and risk mitigation strategies in the Ain Ouassera region.

“…The milliequivalent ratio of Ca 2+ +Mg 2+ to HCO3 -+SO4 2-is another important indicator for revealing the sources of water salinity in groundwater. Values above the 1:1 line indicate the influence of carbonate mineral weathering and dissolution, while values below the line indicate the control of silicate mineral weathering (Chen et al 2022). As shown in Figure 5 (a), 79% of groundwater points have a higher concentration of SO4 2-+HCO3 -than Ca 2+ +Mg 2+ , indicating that the major contribution of Ca 2+ +Mg 2+ in groundwater comes from the dissolution of silicate minerals.…”

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 Banggou 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. The chemical composition of groundwater is mainly controlled by evaporation, rock weathering, human activities, oxidation of pyrite, and desulfurization reactions. 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. The presence of NO3− is attributed to anthropogenic influences. 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 occur from recharge to discharge zones.

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.
