ABSTRACT
Background: The groundwater suitability for irrigation is an important factor for sustainable development of the Qalaat Mgouna region, situated South of Morocco under Saharan climate conditions. The irrigation practice is locally related to the expansion of agricultural activities of demographically developing population in an environment of limited water resources. Objectives: This study is aimed to the assessment of the groundwater quality and its suitability for irrigation purposes as well as the identification of possible water-rock interactions that control the groundwater geochemistry. Material and Methods: The groundwater suitability for irrigation in Qalaat Mgouna area was evaluated by processing available data on major ions concentrations, pH and electrical conductivity (EC) besides calculating quality indices including total dissolved solids (TDS), total hardness, sodium percentage, residual sodium carbonate (RSC), sodium adsorption ratio (SAR) and permeability index (PI). Principal component analysis was conducted to assess the relationships between the used variables, while processes controlling the water chemistry were revealed by determining the water facies according to Piper classification and using geochemical diagrams. Results: The data processing showed acceptable values for pH (7.31-7.73), Salinity (502.93-1457.42 mg/l) and total hardness (22.82-70.44 °fH). Mixed, Ca-Mg-HCO3 and SO4-Cl-Ca-Mg water types were detected reflecting thus possible water-rock interaction. The Wilcox diagram revealed that waters are mainly of good to permissible quality. Conclusions: The geochemical study helped to conclude that water quality in Qalaat Mgouna is controlled by water-rock interaction processes and water is suitable for irrigation according to internationally used standards.
Keywords: Groundwater Quality, Water Chemical Facies, Water-Rock Interaction, Environmental Sustainability, Qalaat Mgouna, Morocco
