In order to better understand the hydrogeological functioning of the Menzel Bourguiba aquifer system (NE Tunisia), chemical and isotopic (18O, 2H) analyses of water are carried out. This work highlights the fact that the water of this aquifer system is highly modified by geochemical interactions: cationic exchange and precipitation/dissolution phenomena. By using isotopic tools, it was shown that the water of this aquifer system has been recently recharged by direct infiltration from the boundary and in the valley of wadis.
