The Rharb hydrogeological basin, of which our study area is part, is one of the main sources of drinking water and irrigation for a large part of northern Morocco. The groundwater of the Rharb basin is characterized by its poor quality, which may be related to its high mineralization. In order to characterize these features, we have applied an approach that relies on the compilation of hydrochemical parameters, hydrogeological drilling, and geophysical data (VES and well logs). The main objective of this work is to highlight some of the features in the geometry of the quaternary deposits and identify the origin of the groundwater mineralization as well as study its spatial variability. The obtained results showed that the geometry of the Amirian bedrock is mainly constituted by two depressions separated by NW–SE and NE-SW trending faults. The main chemical facies of the groundwater are a mixture of calcium and magnesium sulfate chloride facies and chloride-sodium facies. The origin of this mineralization is related to reverse ion exchange processes, halite and gypsum dissolution, in addition to the processes of evaporation-crystallization and water–rock interaction under geological conditions that favor residence time. Such results open up new perspectives for the sustainable management of this important hydrogeological groundwater area. [ABSTRACT FROM AUTHOR] |
