“…However, it is increasingly vulnerable to pressures related to population growth, urbanization, and land cover changes (Yuan et al 2023;Sahadevan and Pandey 2023). This is particularly true in arid and semi-arid areas owing to paucity of surface waters (Reghais et al 2023). In the Banggou 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 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.

Groundwater is the primary source for human life, intended for consumption and agricultural production, particularly in the F'kirina plain, a semi-arid region in eastern Algeria. The study aims to determine the hydrogeochemical characteristics of groundwater, including (Ca2+, Mg2+, Na+, K+), CO3, HCO3−, Cl-, SO42−, NO3, PO4−, temperature, pH, electrical conductivity (EC), and total dissolved solids (TDS). The results were analyzed using XLSTAT software (2016) with Principal Component Analysis (PCA), Piper diagram, and four hydrochemical facies. Their suitability for human consumption was assessed by calculating the Water Quality Index (WQI) according to World Health Organization (WHO) standards (2011), with a WQI below 50 considered suitable for human consumption. Samples P3, P5, P6, and P15 were classified as excellent groundwater quality (WQI < 50), while samples P4, P7, P8, P9, P17, and P18 indicated good quality (50 < WQI < 100). However, 50% of the wells showed elevated levels of major elements exceeding the standards. The observed sequence of major element dominance is high quantities of Ca2 + > Mg2 + > Na + > K+, and the anions follow the order of Cl− > SO4 2 − HCO3 − > NO3 −> NO2 −. PCA results revealed two factors influencing overall hydrogeochemistry: geogenic impact attributed to the geological substrate and secondarily to prevailing geochemical (redox) conditions. Conversely, anthropogenic impact is primarily related to agricultural practices leading to nitrate enrichment and salinization. These factors contribute to groundwater quality degradation in f’kirina plain.
