Abstract

This study examines groundwater quality in theFeija alluvial plain, southeastern Morocco, shedding light on theimpacts of agricultural overexploitation and climate change.Employing the Water Quality Index (WQI) and GeospatialAnalysis (GIS), it evaluates the suitability of water for domesticand agricultural uses through seasonal analysis of samples. Thedata reveal a wide variation in water quality, with some regionshaving average to poor M'nasra aquifer and the Tinzoulineaquifer (Draa, Morocco). Some research is being carried outTinzouline and M'nasera aquifers.The Feija aquifer boasts a heterogeneous composition,comprising Plio-Quaternary terrains of varying thickness. Theanalysis identifies diverse chemical facies of groundwater,encompassing calcium bicarbonate, sodium chloride, andchloride sulfate, calcium, and magnesium. These characteristicsmirror the influence of both human activities and naturalconditions on water quality. The spatial distribution of the WQIpredominantly indicates good water quality, albeit withvariations attributed to agricultural practices and the uniquegeology of the region, particularly noticeable at sites P5 and P6where quality is diminished.In terms of agricultural use, quality indices suggest marginalwater suitability, with concerns revolving around salinity andsodium, necessitating vigilant management to upholdagricultural sustainability. Lastly, the study unveils an absenceof significant nitrate pollution, with groundwater maintainingcleanliness. These findings underscore the significance ofmonitoring and managing water resources to tackle current andfuture challenges posed by agriculture and climate change in theregion.
