The Hindon River serves as a vital source of freshwater for the majority of the rural residents in western region of Uttar Pradesh, India. Industrial effluent that contains potentially hazardous concentrations of heavy metals is discharged into the river. The goal of this study is to estimate the amount of heavy metal (such as Fe, Mn, Zn, Cu, Cd, Cr, Ni and Pb) con-tamination in the Hindon River and groundwater in the basin of Hindon river using the Contamination index and Nemerow pollution index. Water samples from pre and post monsoon season were collected. Contamination index having value >1 is considered as contaminated. Study area including both pre and post monsoon season having values of contamination index <1 showing no major contamination. High value of contamination index and Nemerow pollution index during pre-monsoon in comparison to post-monsoon is observed both for groundwater and river water. When the estimated Nemerow pollution index value is PI >1 and <5 (Water not suitable for drinking), it indicates that the river and groundwater recourses are contaminated. Study area having Nemerow pollution index values >1 and <5 showing unsuitability of water for drinking purpose. Principal component analysis results of groundwater samples showed that Pb, Ni, Mn during pre and Cu, Cr and Mn during post monsoon seasons are dominating heavy metals. While Principal component analysis results of River water samples showed that Zn, Mn, Pb during pre and Cr, Cu during post monsoon season are dominating heavy metals. Hence, a complete inventory of groundwater as well as river water resources leads to better understanding about the current site specific pollution estimation and future policy making.
