“…The chemical composition of groundwater is a function of the chemical composition of the aquifer host rocks, flow conditions and residence time in the aquifer (Back and Hanshaw 1971). The spatial variability is frequently determined by the intensity and diversity of anthropic activities (Shil'Krot andYasinski 2002, Shrestha andKazama 2007). The use of the major ions as natural tracers has become a common methodology to delineate flow paths in aquifers (Back 1966, Eberts and George 2000, Plummer and Sprinkle 2001, André 2002, Güler and Thyne 2004, Belkhiri et al 2010.…”

Five-year monitoring of physicochemical parameters was performed with two campaigns in low and high water periods of the Lower Soummam catchment. Data from 18 wells were processed by multivariate statistical tools in order to identify the principal factors influencing groundwater chemistry. Two matrices of 14 and 8 physicochemical parameters with 18 groundwater samples collected in wells were obtained. The correlation matrix showed strong associations between nine variables: K + , Ca 2+ , Na + , SO 4 2− , Cl − , Mg 2+ , NO 2 − , Zn 2+ and Sr 2+. Principal component analysis and factor analysis showed that the cumulated variance of high and low water periods was of 83.19% and 78.55%, respectively. The variables assigned to the mineralization effect or to pollution indicators were presented by the factor analysis. The bivariate plots confirmed a mineralization model, ascribed to dissolution of geological materials, and to high levels of saline contamination attributed to leakages from sanitary systems. They also showed an increase "upstream to downstream" of the mineralization, visualization of temporal variations, and a dilution process identification of the natural mineralization during the recharge of the aquifer.
