Assessment of heavy metals and physico chemical parameters of water samples of the vicinity of the municipality dumping sites of Karimganj district, Assam, India

A total number of six water samples have been collected from Naughty Khal, a canal connects the municipality waste dumping site and Longai river of Karimganj district during month of August, 2011. A uniform distance between the collection sites has been maintained during the collection of the sample. Analysis have been done for the quantitative determination of the concentration of Fe, Mn, Cu, Cr, Cd, As and also for the qualitative determination of physical parameters like pH, EC, TSS, TDS, TS and total hardness of the collected water samples. The concentration 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 6.60–7.41 and 7.43–9.91 ms/cm respectively. TSS, TDS, TS and total hardness were found to be within the permissible limit declared by WHO.
