Water quality of a water body is characterized by its physico-chemical and biological features. All these features reflect on the pristine nature of the river. Due to unplanned urbanization, rapid growth of industrialization and other anthropogenic activities such as dispersal of dead bodies, discharge of industrial and sewage wastes, the quality of a Ganga river body is deteriorated day by day. The present study is an attempt to demonstrate the rate of deterioration of the water quality of river Ganga at Patna, Bihar and its effects on the primary productivity of the river. For this, various physico-chemical and biological parameters i.e pH, DO, BOD, total coliform and faecal coliform, were studied for one year from April 2018 to March 2019 and noticed the changes on these parameters due to urbanization, agricultural runoff and other anthropogenic activities. The result conclude that such as pH, DO and BOD parameters are well within the limit, but total coliform and faecal coliform found beyond the prescribed standard limits in the present investigation hence water quality of this Ganga river water is deteriorated at Patna. Water quality of this river is also not suitable of growth of phytoplanktons, bathing and domestic purpose.
