      abstract     = {Cap Skirring area is located in the southwestern part of
                      Senegal, where groundwater is the only resource for drinking
                      water supply. The present study helps to assess and
                      determine the most dominant hydrogeochemical processes
                      controlling the groundwater quality in the Cap Skirring area
                      in Southwestern Senegal. For these purposes, 23 groundwater
                      samples have been collected and analyzed for pH, Ca2+, Mg2+,
                      Na+, K+, SO42-, Cl-, HCO3- and NO3- concentrations and the
                      indices total hardness (TH) as well as total dissolved solid
                      (TDS) were calculated based on the analytical results. The
                      analysis indicated that the groundwater in the study area is
                      generally soft. Comparison of these chemical data with the
                      WHO drinking water standards showed that WHO standards were
                      exceeded mainly in wells D30 (Ca2+, HCO3-) and PD122 (Cl-,
                      NO3-, Na+ and K+), both located in the eastern part of the
                      area. The Piper, Shadha, and other bivariate diagrams
                      presenting the geochemical facies of the groundwater showed
                      the HCO3 – Ca – Mg as the dominant water type (65.2
                      $\%)$ followed by the Cl – Na – K water type (21.7
                      $\%),$ and the Cl – Ca – Mg water type (13.0 $\%).$ This
                      hydrogeochemical characterization indicates that the
                      groundwater is mainly recharged by the high seasonal
                      rainfall that occurs in the area. Salinization conditions
                      and reverse ion exchange reactions were also observed in the
                      some groundwater samples. This salinization process was
                      mainly found along the eastern part (“bolong”) of the
                      study area in samples taken at PD 122, PD 144, PD 55, and
