The present study aims at examining the river bed sediments for the distribution of organic matter and toxic heavy metal in the Amaravathi River. Two sediment samples were collected at both the banks from 6 sampling stations. The samples were acid treated and the concentration of metals, like lead, copper and iron were recorded using atomic absorption spectrophotometer. The total organic matter and physico chemical parameters were analysed for all the samples. Most of the heavy metals have precipitated and settled into the river bed as carbonates, oxides and hydroxides. The pollutants are deposited in association with very fine particles of silt and clay. The silt and clay act as adsorbents along with the inorganic and organic mattes.
