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 recources and pollution.
To the challenges of the increasing water demand generated by rapid urbanization, groundwater resources become threatened
and water quality becomes poorer. For this, analyzes were made in the aquifer town of Gafsa and showed an average salinity of
water about 4.2 g / l.
The strong mineralization of water, due to ions: SO4
2- with almost 1118.45 mg / l, Cl-
, Na + and Ca + + respectively 871.82,
619.48 and 372.63. We also note the important values of nitrate sometimes reaching 278mg / l. Among the polluant elements, we
found fluorine with a maximum of 2.78 mg / l and manganese with 0.04 mg / l.
