  abstract = {{T}his study was conducted to determine the main hydrogeochemical processes controlling the mineralization in the {A}ngads groundwater in {N}orth-{E}ast {M}orocco. {T}o achieve this, hydrogeochemical compositions combined with multiple stable and radioactive isotopes ({O}-18, {H}-2, {H}-3, and {C}-14) were analyzed in groundwater. {S}tatistical analysis showed that average ion concentrations in groundwater were in the following order: {N}a+ > {C}a2+ > {M}g2+ > {K}+ > {NH}4+ for cations, and {C}l- > {HCO}3- > {SO}42- > {NO}3- for anions. {T}he aquifer is mainly composed of {C}a-{M}g-{C}l type waters, which account for over 70 % of the samples. {T}he results show that water mineralization is mainly due to the dissolution of evaporites, as well as the influence of ion exchange, and probably a part of evaporative enrichment. {T}he {H}-2 vs {O}-18 diagram revealed that aquifer recharge is more depleted isotopically than the local rainfall, pointing to a recharge in high elevation mountains to the south/south-east of the zone, and that all points are influenced by evaporation before or during infiltration. {T}he levels of {H}-3 indicate that all samples show a limited recent water component mixed with an older component dated back to 2233 {BP} according to {C}-14 measurements.},
