Abstract : The River Kali is an important surface water body in the western Uttar Pradesh (U.P). It is an intermittent river which flows throughout the monsoonal months. The present study aims to assess the heavy metal contamination in the river Kali using pollution index (PI), based on five heavy metals (Fe, Zn, Cd, Pb, and Cr) during pre and post monsoon seasons in the year 2014. The PI evaluated during pre and post monsoon seasons with respect to drinking water quality standards was found as 5.04 and 7.08 respectively, while related to inland water quality standards were found as 4.37 and 3.62, respectively. The results indicate that the river Kali was severely contaminated (PI>3) in both seasons. Therefore, water of Kali River is not fit for drinking as well as for agriculture purposes.
