Abstract: Quality assessment of water samples both from surface and sub-surface sources of Amdanga block of West Bengal was done during April- May 2004. About 80.5% samples were in medium salinity class (C2) and rest was without any salinity hazard. Sodium Adsorption Ratio (SAR) did not pose any threat towards its use, however, HCO3 being the dominant anion leading to high Residual Sodium Carbonate (RSC) values (>2.5 me L-1) made these unsuitable for irrigation purpose. The average concentration of Fe, Pb, Ni and Co in all the sources of irrigation water was within the safe limit, but the concentrations of Mn, Zn and Cu were beyond the recommended maximum concentration for irrigation purpose.
