Strontium (Sr) is one of the uncommon heavy metals found in the sediments of river. It has drawn an attraction towards its distribution in the Kortalaiyar river basin in the present study. Hence, an attempt has been made to analyze the concentration of the metal in the 30 sampling locations in the stretch of the river. The extent of pollution by this metal is assessed using various pollution indices like Geoaccumulation index, Contamination Factor and Enrichment Factor. A complete study has been done on the existence of Sr in the Kortalaiyar river. The outcome of the study gives valuable information regarding the moderate pollution of the river by Sr metal.
