The seasonal variation of water quality of the river Hindon in Ghaziabad, India was evaluated using environmetric techniques and metal pollution index. Various environmetric methods were tested for source apportionment and identifying the variables responsible for seasonal variations in river water characteristics. Source analysis indicated that in the pre-monsoon period, the metal contamination in river water was due to the disposal of industrial and urban wastewater. The order of metals as per River Metal Pollution Index (RMPI) as follows Pb > Cd > Zn > Cr > Cu > Fe > Ni. The RMPI indicated high pollution at S-3, S-5 and S-6 (IMPI > 2) and moderate pollution at S-1, S-2 and S-4 (IMPI ≤ 2). Based on IMPI ranking, the order of all the monitored sites was as follows: S-3 > S-5 ≥ S-6 > S-4 > S-1 > S-2. This finding of the present study demonstrated the necessity and usefulness of integration of environmetric analysis and pollution index method in monitoring river water quality. © 2016, Institute of Integrative Omics and Applied Biotechnology.
