Therefore, 29 groundwater samples were collected from this area to assess their hydrogeochemistry and suitability for irrigation purposes. The groundwater samples were analysed for distribution of chemical elements Ca2+, Mg2+, Na+, K+, HCO3 −, Cl−, and SO4 2−. It also includes pH, electrical conductivity. The hydrochimical study has shown that the facieses are changing between a pole calcium-chloride-sulphate and sodium-chloride types. The results also showed that the salinity is the major problem with water for irrigation use (58% of samples fall into C3S1 class). As a result, the quality of the groundwater is not suitable for sustainable crop production and soil health without appropriate remediation.enArticle
