Abstract: The present study was carried out to assess and categorize the quality of the underground water of village Butlaw and Dabhalia in Navsari district of Gujarat. It was found that the pH of water samples was neutral to alkaline in nature ranged from 7.25 to 7.81 and 7.17 to 7.67 during pre and post-monsoon seasons with the mean values of 7.50 and 7.39 respectively. EC values of groundwater during the pre-monsoon season was found ranged from 0.84 to 1.31 dS m^-1 with a mean value of 1.01 dS m^-1 while during the post-monsoon season it was found ranged from 0.77 to 1.22 dS m^-1 with a mean value of 0.92 dS m^-1. From the salinity point of view, all the water samples were classified as high-salinity water (C3) groups. The pre-monsoon season SAR values were found ranged from 1.39 to 3.82 with a mean value of 2.77 whereas in the case of post-monsoon season SAR was found ranged from 1.27 to 3.74 with a mean value of 2.62. In terms of sodium hazard, all the water samples were classified as low-sodium water (S1) groups. A highly significant positive correlation of SAR was found with the RSC during both the seasons (r=0.600** and r=0.592**). Due to the presence of salinity hazards in the groundwater, it will be better to use surface water for irrigation purposes. If there is less availability of surface water, irrigation with groundwater should be done after ensuring well drainage facilities in the fields.
