  abstract = {{I}n this study, hydrogeochemical analyses were combined with geographic information system ({GIS}) tools to investigate salinization sources of groundwater in the downstream part of the {E}ssaouira basin, and to analyze the spatiotemporal trends in groundwater quality. {T}o assess groundwater suitability for drinking purposes, the quality of sampled water was compared with the {W}orld {H}ealth {O}rganization ({WHO}) and the {M}oroccan guidelines. {W}ilcox and {US} salinity laboratory ({USSL}) diagrams were used to evaluate groundwater suitability for irrigation. {H}ydrogeochemical analyses revealed that groundwater is of {N}a-{C}l and {C}a-{M}g-{C}l types. {T}he analyses of the correlation between the chemical elements showed that the water-rock interaction and the reverse ion exchange are the major processes impacting groundwater degradation in the study area. {T}he study of groundwater suitability for drinking and irrigation purposes shows that groundwater quality in the study area is permissible, but not desirable for human consumption. {A}dditionally, groundwater is permissible for agricultural use but with high-salinity hazards. {T}he spatial distribution of the physicochemical elements shows a general upward gradient from the north to the south and from the east to the west. {T}he trend in groundwater quality during the last five years shows a shifting in the quality from the mixed {C}a-{M}g-{C}l to the {N}a-{C}l type.},
