Hydrogeochemical evolution and mineralization origin in a semi-arid shallow aquifer: a case study of the Barika area in northeast Algeria

Most Middle Eastern and North African regions are characterized by an arid semi-arid climate. As such, the drinking water supply management have become a challenging task for local regional authorities. The Mio-Plio Quaternary aquifer of Barika area is only irrigation reservoir in region. objective this paper to identify origin evolution process groundwater mineralization using major elements as indicators. To achieve samples were collected, from several boreholes drilled aquifer, June 2018 March 2019, subsequently analyzed. results obtained terms Gibbs plot, Piper, chemical correlation, statistical analysis data identified origins mineralization. dissolution evaporated minerals, precipitation carbonates, evapotranspiration, ion exchange reactions been primary processes physicochemical showed that these waters consisted mainly chloride, calcium sulfate, magnesium facies types with slight change some during two sampling periods. This due interactions the-aquifer geology scarcity caused climate change.
