ABSTRACT

Lakkavalli tank in Chikmagalur district was studied for Physico-chemical and trace metal parameters at five sites, for a period of six months (March to August 2017). This water body has been subjected to human activities periodically and water quality is deteriorated intensely. Agriculture, human activities and discharging of sewage creates serious threat to the biota of the tank by altering the water quality. Different parameters studied were pH, electrical conductivity, nitrogen, phosphorus, zinc, copper, iron and manganese content. The results obtained from the current study indicated that the water pH of Lakkavalli tank was alkaline in nature, EC, nitrate and phosphate contents were in moderate concentrations. Manganese and iron levels of sediment sample in Lakkavalli tank shows maximum level of pollution and ecological balance is totally disturbed. One-way ANOVA was calculated to know the significant difference between the samples. Keywords: pH, Electrical conductivity, nitrate, phosphate, trace metals
