Lakes sediments consists of biological and non biological matter accumulated since from formation of the lake. Sediment sequence in lake represents information about the activities within the lake and in its catchment area over a period of time since its inception. Hussain Sagar Lake located in the heart of Twin Cities of Hyderabad and Secunderabad receives toxic substances from the industrial effluent discharges in to it through incoming nallas. Pollutants entering the lake undergo either absorption or adsorption by fine particles present in the lake water, which may in turn settle down in the form of sludge. The sludge is further classified into pore water and sediments. This paper aims to explain the Physico chemical characteristics of sediments and pore water of Hussain Sagar Lake.
