The study of the trace metals and heavy metals present in the Poondi reservoir plays a vital role in determining the extent of pollution in the study area. Overexploitation of nature and uncontrolled use of natural resources, including inadequate processing of industrial wastes have caused large contamination of world ecosystems by toxic metals which generally show considerable accumulation in aquatic sediments. .The present study deals with the impact of pollution on the five different sampling sites in and around the Poondi reservoir.The results of the assessment reveals the effect of this sediment bed in polluting the river Kortalaiyar which flows through Poondi reservoir collecting the pollutants along its flow. The Pearson‟s correlation matrix reveals the correlation between various metals indicating their proximity in origin and their distribution pattern
