Drinking water pollution causes health problems which can be prevented by taking appropriate actions. Water quality index (WQI) is effective way to communicate and parameterize quality of water. The data obtained through quantitative analysis of water is measured up against WHO water quality standards to calculate water quality indices. The purpose is to assess river water pollution and effect of monsoon at Moradabad (Uttar Pradesh). Water quality index (WQI) for Gagan river water at thirteen different sites at Moradabad has been calculated for pre-monsoon period and after onset of monsoon with the help of estimated values of seventeen different physico-chemical parameters and WHO water quality standards. River was polluted at all the sites that were studied for both periods. At almost all the river water sites, the water quality shows some improvement after the onset of monsoon, however, river water was still severely polluted. Higher estimated values of various parameters on the basis of water quality indices also support and verify the results of river water pollution. Mixing up different effluents with river water multiplies the river water pollution. People that are exposed to such severely polluted water are threatened and water quality management is imperative in the catchment area of study.
