Fresh water comprises of water from River, ponds and well. Contamination of this water by metals, namely, Calcium, Magnesium, Copper, Iron, Zinc and Manganese were evaluated in the samples of fresh water. The analysis was done complexometrically in the presence of surfactant. The distribution of metals in Water samples analysed were in the order of magnitude as by Ca>Mg> Cu > Fe > Zn > Mn. The highest concentration level of copper was observed in pond water. The lowest concentration levels of Manganese were observed in shivnath river sample. These levels of heavy metals of five freshwater samples exceeded the maximum permissible limits values. These levels of heavy metals might be due to the increase in agricultural influx waters, domestic wastes and some anthropogenic activities
