  abstract = {{D}uring the last decades, the coastal areas of {M}orocco have witnessed an intense socioeconomic development associated with a continuous population growth and urban extension. {T}his has led to an overexploitation of coastal aquifers leading to a degradation of their water quality. {I}n order to obtain large scale overview on the quality status of {M}orocco's coastal aquifers ({MCA}) to assist national water managers to make informed decisions, a comprehensive scrutinization of the {MCA} against common indicators and using unified methods is essential. {I}n this study, databases from thirteen {MCA} were analyzed, using multivariate statistical approaches and graphical methods in order to investigate the degree of mineralization in each aquifer and to identify the main salinization processes prevailing in groundwater. {T}he results showed that the dominant groundwater types are {N}a-{C}l, {C}a-{M}g-{C}l, {C}a-{M}g-{SO}4, {C}a-{M}g-{HCO}3 and {C}a-{HCO}3-{C}l. {T}he {G}ibbs diagram and the seawater contribution (0-37%) indicate that the mineralization is mainly due to the seawater intrusion and water-rock interaction. {T}he salinity degree diagram illustrates that almost all groundwater samples are located in the moderate to very saline zone, indicating that {MCA} are recharged by water from variable sources. {T}he groundwater quality assessment shows a deterioration, particularly by seawater intrusion and significant nitrate pollution. {T}he temporal evo-lution confirm that the {MCA} are influenced by seawater namely in the {A}tlantic part. {T}he {W}ilcox and {USSL} di-agram indicate that the majority of sampled water are unsuitable for irrigation uses. {I}n addition, and by referring to the {WHO} and the {M}oroccan standards for water potability, large number of samples from the groundwaters of the {MCA} is not fully adequate for drinking purposes. {A} set of management actions (e,g., artificial recharge) are proposed in order to mitigate the effect of groundwater overexploitation and seawater intrusion to ensure the sustainability of {MCA}.},
