  abstract = {{T}he aim of this present study was to evaluate groundwater quality in the upstream part of the {E}ssaouira basin. {A} detailed geochemical study of groundwater region is described, and the origin of the chemical composition of groundwater has been qualitatively evaluated, using multivariate statistical methods ({PCA}, {HCA}), and {W}ater {Q}uality {I}ndex ({WQI}) was used to determine the suitability of water for drinking. {T}o attempt this investigation, 38 samples were analysed for various physicochemical parameters such as temperature, p{H}, {TDS}, {N}a, {NO}3, {K}, {C}a, {HCO}3, {C}l, {M}g, and {SO}4. {T}he results obtained showed that the facies characterizing the study area was a combination of {C}a-{SO}4 and mixed {C}a-{M}g-{C}l. {H}ydrochemical approach based on the bivariate diagrams of major ions indicates that the origins of groundwater mineralization are the result of ({I}) evaporite dissolution; ({II}) cation-exchange reactions; and ({III}) evaporation processes. {T}he {WQI} values range from 82.3 to 390.9, and therefore the water samples can be categorized into five groups: excellent water to water unsuitable for drinking. {I}n global, 61% of the groundwater sampled had poor water quality, 18% were very poor water quality, 16% are unsuitable for drinking, and just 6% represent a good quality. {H}owever, the results of this paper indicate that most water is not safe for drinking and needs further treatment.},
