    HYDROCHEMICAL STUDY OF SOURCES SALINITY IN SHALLOW WATER SPRINGS OF NORTHERN ALGERIAN SAHARA
    (university of eloued جامعة الوادي, 2020-01-01) O., Melouah1*; H., . Zerrouki1
    This study is conducted in The Guerrara Oasis; suffer from high salinity of alluvial aquifer used in drinking and irrigation, the distribution of the drilled wells in the study area is anarchic and water salinity is a subsisting problem all along the year, To evaluate the problem gravity two hydrochemical campaigns are acquired during wet and dry seasons , the results confirms the presence of saliferous bodies affecting water quality, The order of abundance of the ions in the ground water samples is Cl->Na+>SO4 ->Mg2+>Ca2+>HCO3 ->K+ the piper diagram reveals that’s the ground water is Cl- - SO4 - and mixed Cl- - Na+ indicating a evaporitic hydro-chemical type, Multiariate statistics and special geochimestry diagrams are used to evaluate the chemical process responsible in groundwater salinization.
