“…In this regard, different approaches have been used in the evaluation of the groundwater quality for particular uses (Hamed et al 2012(Hamed et al , 2013Besser et al 2017bBesser et al , 2018Hadji 2017). Previous works proved that these waters are often unsuitable for both domestic uses and agricultural activities.…”

“…The Pleistocene and Holocene periods could be responsible for the periodic recharge of fossil groundwaters in North Africa. In the last 70 ka before present (MIS 2 and MIS 3, Würm period), three major humid phases have been identified: the Early Würm Pluvial (MIS 3), lasting from 70 to 40 ka before present, the Middle Würm Pluvial (MIS 3), from about 32 to about 22 ka before present and the Late Würm Pluvial (MIS 2), lasting from about 18 to 11 ka before present (Fontes et al 1983;Ouda 2000;Yermani et al 2002;Guendouz et al 2003;Zuppi and Sacchi 2004;Hamed et al 2008Hamed et al , 2010aHamed et al , b, 2012aHamed et al , 2013Mokadem et al 2016;Hamed 2017Hamed , 2018.…”

Climate change is having short-and long-term impacts on surface and groundwater in the northern part of the African continent. This has led to a wide range of consequences that have added pressure on the groundwater systems in this part of the world. Among such pressures, we can cite the mal-distribution and the irregularity of precipitation and ice, flooding, evaporitic sediments input by the drainage net, water degradation, mud stagnation in dams, dead tranche, drought, decreasing of the natural recharge and increasing of the groundwater abstraction, conflict between trans-boundary waters, desertification, imbalance between the regions, migration, revolution, socio-economic imbalance, etc. Actually, watermonitoring networks indicate noticeable hydrogeologic variations and a rise of the groundwater salinity. It was confirmed by the geochemical analysis of water resources that showed scattered data between the northern part characterized by low mineralized groundwater (TDS ranging 0.4-3 g/l) and the southern area where the salinity ranges from 2.5 to 90 g/l. The obtained values are far above the permissible limits for both human consumption, agricultural and tourist activities. These effects, when compounded, are anticipated to worsen the situation and to constitute veritable threats for social and economic development in these regions of North Africa (Morocco, Algeria, Tunisia, Libya, Egypt, etc.). The potential solutions consist of taking urgent to utilize the intelligent technology (bio and nano-technology), policies relevant policies to manage water resources, and the engagement of private, civil, and international sectors if a major crisis is to be averted (collective effort).

“…Hence, it is tapped only by a limited number of public wells in the Sidi Aïch basin with flow rates varying between 2 and (DGRE, 2010). It is also drained by several geothermic springs in the Ben Younes Mont in the south of the study area with a flow varying between 0.5 and 2 l/s (Yermani, 2000;Bouri, 2008;Bouri et al, 2008;Hamed et al, 2013d). The C.I has its recharge source in the Algerian and Tunisian Atlas Mountains (Appelgren, 2002).…”

The hydrodynamic of the multi-aquifer system (the Continental Intercalaire " C.I " and the Complex Terminal " C.T ") of the North Gafsa basin is largely determined by tectonics (Tebessa-Gafsa fault). The composition of groundwater is controlled by complex reactions at gas-liquid-solid "mineralogical composition of associated rocks" interfaces, which depend on the natural surrounding and potential anthropogenic impact. The hydrochemical data (major ion geochemistry) indicate that these groundwaters are characterized by the dominance a Ca-Mg-HCO 3 /SO 4 and Na-Cl-NO 3 water types. Geochemical pattern is mainly controlled by the
