River Ganga- the life line for billions of people, provides water for the essential requirements of life. However, over the years, it has been subjected to tremendous pressure due to untreated sewage and industrial waste being dumped in to the river at many places and the residues of pesticides and insecticides used in the agriculture are ultimately washed and released in to it. In this study, water samples from river Ganga were monitored for temperature, pH, DO, BOD, COD, TSS, TDS, conductivity and turbidity at four sampling sites on seasonal basis. All the quality parameters were compared with the standard values of BIS. The study of physico-chemical parameters on river Ganga water have shown a demonstrable decline in its quality. Deteriorated water quality of river is known for mounting potential health hazards to people drinking this water and organisms present in Ganga river basin. Further research work is urgently needed to determine the bioaccumulation of these toxic elements in the food web and the associated risks to the ecosystem and human health.
