  abstract = {{T}he sources of groundwater salinization, as well as the recharge modes in the {E}ssaouira coastal aquifer, were investigated using a multi-assessment approach that combines hydrogeochemical, multivariate statistical, and isotopic analyses along with geostatistical and remote sensing tools. {T}he multivariate statistical assessment reveals three types of parameters inducing groundwater degradation in the studied aquifer: (1) natural parameters ({N}a, {C}l, {NO}3, {HCO}3, {C}a, {SO}4, {K}, and {M}g), (2) the anthropogenic impact represented by {NO}3, and (3) the processes controlling {HCO}3 concentration in groundwater. {T}he hydrogeochemical analyses denote the predominance of {C}a-{M}g-{C}l and {N}a-{C}l chemical facies and implicate a multitude of processes that induce groundwater mineralization in the {E}ssaouira coastal aquifer. {T}he stable isotope analyses identify recharge modes, and reveal a recharge dilution effect on groundwater quality close to the river. {T}he interpretation of nitrate levels associated with different land uses suggests that domestic sewer leakage and livestock activities are the major sources of nitrate pollution in the studied aquifer. {T}he adopted multi-assessment approach reveals the complexity and the interconnectivity between the different processes controlling groundwater quality in the {E}ssaouira coastal aquifer.},
