Hydrogeochemical and geophysical investigation were carried out to assess the geochemical water composition and processes governing groundwater hydrochemistry in Marine Jeffara Aquifer, southeastern Tunisia. A total of 74 groundwater samples were collected and analyzed for various parameters such as pH, electrical conductivity and major ions. Statistical and geochemical modeling were performed to understand the processes controlling groundwater geochemistry. According to their dominance, major ions are classified as follows Cl > Na > SO₄ > Ca > Mg > HCO₃. Hydrochemical, Na–Ca–Cl–SO₄, Ca–Na–Mg–Cl–SO₄ and Mg–Ca–Cl–SO₄ are the dominant forms in groundwater, mainly as a result of rock–water interaction and saltwater intrusion. Ten vertical electrical resistivity tests were performed in three profiles. The measured low values of electrical resistivity in the coastal areas indicate saltwater mixing with groundwater, as a result of saltwater intrusion.
