Availability in Egypt is minimal due to a real restriction on the quantity and quality of acceptable water; it also increasingly demand, particularly since reduction share Nile following construction Renaissance Dam Ethiopia. At same time, need for water increases population growth, industrial development cultivation desert land. The country depends significantly its supply groundwater. Wadi Qena represents one most promising valleys, which government land reclamations developments. This study aims assess groundwater drinking irrigation purposes by integrating quantitative analyses GIS techniques. To achieve this goal, 17 samples were collected from Quaternary Nubian aquifer middle southern part Wadi. Chemical analysis major cations anions was carried out at Assuit’s Regional Soil Fertility Laboratory. Maps chemical variables are created using statistical tools combining observations with interpolation models that can incorporate simple process relations. Major ions, total salinity, Na%, SAR, EC, RSC, PI, MH, KR, SSP, TH, Cl − used purposes. Schoeller’s, Stiff’s, Piper’s, diagrams determine hydrochemical facies area. composition reflects Sodium–Chloride main type area, sequence anions, 100% order Na + > Ca 2+ Mg /Cl SO 4 2− HCO 3 . Comparative against standard guidelines indicated exceeded safe levels constituents, TDS, pH, making them unsuitable but potentially suitable high salt-tolerant crops. results maps analytical revealed characterized natural alkali dissolved solids (TDS) increasing ranges sodium absorption (SAR). GIS-spatial model southwest northwest represented highest lowest suitability, respectively, In contrast, parts confirmed values , confirm this. lists corrective measures improve monitoring systems, efficient techniques, localized desalination, artificial recharge projects, stricter waste management agricultural policies will minimize sources contamination. study’s proposed offers universal tool assessment basin similar settings worldwide innovative presented study.
