  abstract = {{G}roundwaters of the {C}ontinental {I}ntercalaire sandstone formations at the eastern piedmont of {D}ahar (southern {T}unisia), where they outcrop, were analysed to study the mineralization, the water origin and the current recharge process. {H}ydrochemical study shows that these waters present a spatial variability of chemical facies which is linked to the lithology of the host rock. {T}he factors contributing to the mineralization are mainly the water-rock interaction in particular the dissolution of evaporitic minerals and the cation exchange reactions. {S}table isotopes show an enrichment in delta {O}-18 and delta {H}-2 contents principally for piezometric levels closest to the surface, reflecting measures found in the current rainfall subject to a semi-arid to arid context. {T}hese results are coherent with those of {C}-14 and {H}-3 that allow the qualitative identification of a current recharge which could probably be supplied by the recent infiltration of waters in {W}adis and by the direct infiltration of meteoric water through the local sandstone outcrops of the basin. {T}his concerns in particular the well of {S}alem ben {S}alem {D}abbabi, showing a content of 1.03 {TU}, and its static level is controlled by the {T}ataouine {W}adi, indicating therefore an evident sign of recent recharge.},
