Heavy metal (Pb, Cd, Cr, Ni ) concentration in water sediments and fish was analysed from Madivala lake in the month of June 2008. There was an appreciable increase in metal concentrations in going from the water to the sediment samples.The Heavy metal concentration, in water was in the order Pb > Cr > Cd > Ni , in sediments Pb > Cr > Cd > Ni.

Water pollution is a serious problem as almost 70% of India
