In the present context of climate change and increasing demand for water, it is crucial to identify the origin, groundwater flow dynamics and mean residence times for sustainable management of water resources. In this study, groundwater residence time and recharge conditions of the deep aquifer of Sfax were investigated using environmental isotopes and noble gases. The results show that Sfax deep groundwater was recharged during cooler period of Late Pleistocene. In broad agreement with evidence from other paleoclimate investigations, the estimated noble gas recharge temperature (NGT) is lower than the present by about 5.5 °C. Oxygen isotopes values of Late Pleistocene are also 1.5‰ lower than modern precipitation.
