North-eastern Algeria is characterised by several thermal springs. The aim of this work is to study the Tamersite spring, which has not received any study and to compare to those relating to the Djaarir spring. For this purpose, four samples were collected from these thermal springs in 2017, having a temperature ranging between 26 and 35°C, anal most neutral pH and high values of electrical conductivity. In order to evaluate the thermal water potential of these springs, we adopted an interdisciplinary approach. The hydrochemical tool shows that hot water is characterised by the presence of two different chemical facies: the first of bicarbonate–sodium type, the second of chloride-sodium type. This analysis allowed also attributing a terriferous, evaporitic origin to sodium, chlorides and bicarbonates. The salinity characterizing these thermal waters is mainly due to deep runoff in cristallophyllian formations and carbonates formations being in contact with the terriferous, saliferous formations.
