  abstract = {{T}he city of {E}ssaouira is located along the north-west coast of {M}orocco, where groundwater is the main source of drinking, domestic and agricultural water. {I}n recent decades, the salinity of groundwater has increased, which is why geochemical techniques and environmental isotopes have been used to determine the main sources of groundwater recharge and salinization. {T}he hydrochemical study shows that for the years 1995, 2007, 2016 and 2019, the chemical composition of groundwater in the study area consists of {HCO}3-{C}a-{M}g, {C}l-{C}a-{M}g, {SO}4-{C}a and {C}l-{N}a chemical facies. {T}he results show that from 1995 to 2019, electrical conductivity increased and that could be explained by a decrease in annual rainfall in relation to climate change and water-rock interaction processes. {G}eochemical and environmental isotope data show that the main geochemical mechanisms controlling the hydrochemical evolution of groundwater in the {C}enomanian-{T}uronian aquifer are the water-rock interaction and the cation exchange process. {T}he diagram of delta {H}-2 = 8 * delta {O}-18 + 10 shows that the isotopic contents are close or above to the {G}lobal {M}eteoric {W}ater {L}ine, which suggests that the aquifer is recharged by precipitation of {A}tlantic origin. {I}n conclusion, groundwater withdrawal should be well controlled to prevent groundwater salinization and further intrusion of seawater due to the lack of annual groundwater recharge in the {E}ssaouira region.},
