In this study water quality of river Longai in stretch of 5 km at Karimganj was investigated for pollution potential by determining various water quality parameter. A total number of fifteen water samples were collected during the summer season. A uniform distance between the collection sites was maintained during the collection of the samples. Analysis was done for the quantitative determination of the concentration of Fe, Mn, Cu, Cr, Cd and As and also for the qualitative determination of

The concentrations of Mn, Cr, Fe, Cd and As obtained were higher than the permissible limit declared by WHO. pH and electrical conductance of the water samples lies between 6.56 to 7.47 and 6.65 to 10.2 mscm-1 respectively. TSS, TDS,TS and total hardness were found to be within the permissible limit declared by WHO.
