	abstract = {Setif city covers an area of 6550\&nbsp;km2; it is located about 300\&nbsp;km southeast of Algiers and 100\&nbsp;km to the south of the Mediterranean sea. The aim of our study is to know the tectonic mechanisms responsible for the emergencies and to highlight their chemical characteristics of water springs in Setif. Wherein thermalism is characterized by the presence of a number of thermal springs, the latest are usually related to recent large fractures deeply affecting the sedimentary formations and sometimes even crystallin basement. These fractures are often injected by Triassic evaporates; their directions are NNW{\textendash}SSE, NW{\textendash}SE, and NE{\textendash}SW and limiting great structural units. Four groundwater facies were identified: the high percentage of sources, staking major accidents related to limestone mountains or to the basement, shows a calcium or sodium sulfate facies; and the sources are often hot (meso or hyperthermal). A second group, related to terrigenous saliferous formations, shows a sodium bicarbonate or sodium chloride facies. The geothermic interpretation allows us to conclude that the reservoir supplies the two aquifer systems of the thermal complex, and is stored in fissured Jurassic limestone, where water storage and circulation is beyond 2600\&nbsp;m deep.},
