Paper Title
Some Heavy Metals of the River Water-A Geological Study

Abstract
The present study is to prepare heavy metal pollution index (HPI) of the Subarnarekha River (India) flowing through the Indian state of Jharkhand and use the applications of environmetrics, also called multivariate statistical techniques, like principal component analysis (PCA)/factor analysis (FA) and cluster analysis (CA) to identify the sources of heavy metals along the river basin. Seventeen locations were selected along the route of the river covering its full length in the Jharkhand state. Six heavy metals viz. Iron (Fe), Zinc (Zn), Copper (Cu), Lead (Pb), Cadmium (Cd) and Manganese (Mn) were analysed using Atomic Absorption Spectrophotometer. The mean HPI (49.12) was found to be below the critical pollution index value of 100. Lowest HPI (20.89) was recorded near the origin of the river and the highest HPI value (82.40) was obtained at the Mango which is a suburb of the Jamshedpur city, one of the most industrialised and populated cities of India. Fe, Cu, Cd and Pb exceeded the desirable maximum value, prescribed by the Bureau of Indian standards (BIS), at the sites closer to the industrial and urban regions. PCA/FA and CA in combination with metal concentrations and correlation analysis proved to be effective tools for source identification and characterisation. Both natural and anthropogenic sources were found to be contributing to the pollution load of the river with the anthropogenic activities dominating the influence.
