Abstract
The Hammam Sokhna thermal springs is located about twenty km south - east of El
Eulma in South Sétifien. It is a large relatively flat depression on the northern limit of a
salt Lake (Chott El Baida).
A series of chemical and isotopic analyses (O
-18
and H
-2
) of aquifers performed in the
Hammam Sokhna area, a large sedimentary basin located in southern Setif, filled with
Mio-Plio-Quaternary deposits, which rest on Jurassic and Cretaceous limestones, show
that the superficial water table made up of thermal waters regroups waters with the most
impoverished isotopic signatures. The recharge is ensured by meteoric water with an
altitude effect. The recharge of groundwater moving in carbonate, karstified formations
is ensured by meteoric water that underwent a slight evaporitic loss. The application of
the various diagrams has shown that the chemical facies of the Hammam Sokhna area
water is of the sodium chloride type.
The binary diagrams show that the water mineralization is controlled by mineral dissolutionprecipitation
processes and by cation exchange. Bacteriological analysis indicates that this
water has a good overall quality.
