“…These highly mineralized resources are often unsuitable for particular uses. In Tunisia, this phenomenon is widely expressed along the Mediterranean costs of the country mainly in the southeastern part (Gabès Gulf) as well as in the Cap-Bon areas (Tunis and Hamamet Gulfs) (Paniconi et al 2001;Trabelsi et al 2007;Agoubi et al 2013;Kharroubi et al 2014). The sea water intrusion in coastal aquifer (Fig.…”

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).

“…The chemical composition of groundwater is related to the solid product of rock weathering and changes with respect to time and space. Therefore, the variation on the concentration levels of the different hydrogeochemical constituents dissolved in water determines its usefulness for domestic, industrial, and agricultural purposes (Agoubi et al 2013). Table 2 shows that TDS ranges from 2.12 to 3.29 g/l with a mean of 2.5 g/l indicating brackish water.…”

Hydrogeological and hydrochemical investigations were applied to explain geothermal groundwater flow factors controlling groundwater mineralization, and 222 Rn concentrations were controlled using RAD7-H 2 O in El Hamma aquifer system, southeastern Tunisia. Nineteen geothermal water samples were collected from different locations (thermal baths and deep wells). Physical parameters (EC, pH, TDS, T) were measured, and major ions were analyzed. Hydrogeochemical modeling and thermal parameters reveal that groundwater from El Hamma aquifer system has several origins. The first type was characterized by a hot temperature >55°C with a chemical facies Na-Mg-Ca-SO 4 -Cl . This type characterizes lower cretaceous deep water (continental intercalary aquifer). The second water type was dominated by Na-Ca-Cl-SO 4 facies with a temperature <45°C and represents the superficial aquifer. However, Ca-SO 4 -Na-Cl-Mg is the third water type which is characterized by mixed water from deep and shallow water with a temperature ranging from 45 to 55°C. Shallow aquifer displays higher 222 Rn concentration (677 to 2903 Bq/ m 3 ). However, deep water from continental intercalary displays relatively a low radon concentration (203 to 1100 Bq/ m 3 ). Compared to Rn-222 activity in some countries, radon concentration in El Hamma thermal aquifer system has a medium value controlled by structures, porosity, and permeability of aquifers. Variographic analysis and ordinary kriging techniques were used to map temperature spatial variability in the study area. Geostatiscal techniques in addition to geological data and radon activities confirm the existence of vertical communication between continental intercalary aquifer and superficial Senonian aquifer through vertical faults system.

“…Therefore, water suitability for irrigation use is de-termined not only by the total amount of dissolved solids but also by the kind of salt [SARKAR, HASSAN 2006]. According to OBIEFUNA and SHERIFF [2011], the irrigation water quality is judged by four accepted criteria: (1) TDS, (2) relative proportion of sodium to other cations, expressed by sodium adsorption ratio (SAR), (3) chlorine (Cl − ) or/and boron contents, and (4) residual sodium carbonate [AGOUBI et al 2013].…”

The population increase, urbanization and intensification of agriculture and demands for water supply in the coastal plain of Collo led to excessive pumping of the unconfined aquifer with limited dimensions. This study aimed to characterize the effect of the overexploitation of the groundwater from the only unconfined aquifer in the region, what resulted in the inversion of the groundwater flow and the rise the possible seawater pollution that is shown in the water table map. The causes and effects of the saltwater intrusion were discussed. The interpretation of the electrical conductivity measurements, chloride and sodium maps have shown clearly the areas where values were the highest with tighter curves towards the sea, the wadis Guebli and Cherka. These values distribution indicated a marine source of salinity in wells and boreholes close to the sea and wadis.
