چکیده

batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (ec) of both surface and groundwater samples were slightly higher than that of acceptable limit ( ca2+ > mg2+ > k+ in both surface and groundwater while the anions trend in both surface and groundwater of the study area were cl¯ > so42¯ > po43¯. ec and tds showed high positive correlation with na+, k+ and ca2+ with cl¯ as confirmed from correlation matrix and principal component analysis (pca). most of the stw water samples compared to the surface water had higher soluble sodium percentage (ssp) values while sodium adsorption ratio (sar) indicated the surface water and ground water with low sodium hazard. the kelly’s ratio of stw water is more subjected to sodium hazard compared to surface water in the study area.
