“…It refers to the majority of Maastrichtian samples located generally above the LMWL and presenting an enrichment of both heavy isotopes, whereas the Cenomanian and Eocene water samples are plotted below the two meteoric water lines composing Group 2, characterized by intense evaporation of the rainfall water during infiltration in carbonate fractures. Isotopic analysis from the Tebessa region indicates that groundwater from the karst aquifer is of meteoric origin (Chabour et al, 2021;Hamad, Baali et al, 2018;Kouadra et al, 2019;Legrioui et al, 2020). This must therefore be rapid, taking place through a fissure and/or karst network.…”

This research aims to assess the hydrogeochemical evolution and the assessment for drinking and irrigation use of the spring water from the alluvial aquifer and major karst aquifer systems in Tebessa (the northeastern part of Algeria). For achieving this goal, 25 groundwater samples from several springs, including thermo-mineral springs, were examined and subjected to multivariate statistical analysis (principal component analysis), isotopic approaches, and geochemical modelling. However, it was revealed that the hot waters interact at depth with Triassic evaporates located in the hydrothermal conduit (fault), giving rise to the Na+-Cl- water type. Furthermore, the freshwater characterized the karst aquifer marked by the Ca2+ HCO3 - water type with low salinity concentrations. On the other hand, the majority of cations and anions and electrical conductivity, which characterize the chemical composition of the overall water springs, were below the limits allowed for drinking water according to the standards. In terms of hydrochemical facies, it was discovered that throughout the study area, two chemical facies were predominant (Ca2+- HCO3 - and Na+- Cl-). Water-rock interaction, characterized by the dissolution of carbonates and silicates, plays a primordial role in the chemical composition of the groundwater. Stable isotopic analyses of the δ18O and δ2H compositions of the waters suggest that the cold waters of the study area are of meteoric origin. Anyway, it was concluded that the meteoric recharge was precipitation, which recharged from a higher altitude (600–1700 m) and infiltrated through deep faults and fractures in the carbonate formations of the Tebessa Mount.

This research aims to assess the hydrogeochemical evolution of the groundwater in Oued souf valley for drinking and irrigation purposes. To achieve this, 49 groundwater samples from the complex terminal were examined and treated concurrently with multivariate statistical methods, geostatistical modeling and the WQI (water quality index). Focusing on the physico-chemical parameters, Q mode clustering analysis detected four major water groups, where the mineralization augmented from group 1 to group 4. The hydro-chemical type was the same, Ca-Mg-Cl-SO4 for all the groups. Calcite, dolomite, anhydrite, and gypsum would be the dominant reactions with the undersaturation of evaporates minerals, based on geochemical modeling, while the carbonate minerals are precipitating. Geostatistical analysis using ordinary Kriging demonstrated the exponential semi-variogram model fitted for EC (electrical conductivity), Ca2+ (calcium), Mg2+ (magnesium), K+ (potassium), HCO3− (bicarbonate), Cl− (chloride), and SO42− (sulfate). At the same time, the rational quadratic model was the best-fitted semi-variogram model for Na+ (sodium) and NO3− (nitrate). EC, SO42−, and NO3− have a strong spatial structure, while Ca2+, Na+, K+, and HCO3− have a moderate spatial structure. Moreover, there was a weak spatial structure for Mg2+ and Cl−. The WQI shows that CT (complex terminal groundwater aquifers) are not suitable for drinking and their quality for irrigation fluctuates from excellent to moderate quality.
