摘要：The physicochemical and microbiological studies on water and sediments of LakesKelageri, Salakinakoppa, Navalur, Nuggikeri and Neersagar were carried out. Mostof the physicochemical characteristics are within the permissible limits of BIS andWHO standards for drinking water except Salakinakoppa lake. Some samples werefound to be highly contaminated with coliforms including E. coli. In all the lakes,some species of zooplankton were recorded. This investigation brought to thelimelight that except Neersagar lake, the water of other lakes is unsuitable fordrinking purposes but useful for agricultural and domestic purposes. The heavymetals such as iron, copper, lead, manganese, zinc, cadmium and magnesiumwere analysed in the water and sediment samples of the above lakes using atomicabsorption spectrophotometer. The results revealed that by and large, all the metalsexcept cadmium were present in the samples in various concentrations. Thenutrients like N, P, K, etc. were also found in the samples.
