Abstract
In Tunisia, as in most semi-arid countries, the problems of access to water populations are acute especially with irregularity of rainfall and arid climate combined with the insufficiency of natural water resources and pollution. This study consists in the identification of the factors which influence the water quality parameters in the aquifer of Gafsa, located in the south?west of Tunisia. Rapidly increasing urban population, growth rates over the last few decades have been responsible for the production of huge quantities of wastewater, often evacuated without any particular treatment especially in the septic tanks. Groundwater samples for chemical and microbial analysis were collected from 19 drillings spread throughout the study area. Results showed significantly elevated levels of sodium, chlorides, sulfates, nitrates and coliform bacteria all over the urban area. High levels (NO3: 8.8?278 mg/l; Na:4002 mg/l; Cl:6526 mg/l; Coliforms [72/100 ml) can be related to more densely populated areas. Alternatively results showed a very variable salinity composition of groundwater, ranges from 0, 96 to 15, 03 mg/l. We also note that among pollutant elements, we found fluorine with maximum of 2.78 mg / l and manganese with 0.04 mg/l. Finally methods of controls must be established in order to stop this pollution.
