ABSTRACT- This study is an attempt to analyze the water quality of river Ganga in Patna district. Water samples were collected from 16 different Ghats during March-May 2017. Due to heavy discharge of municipal waste and anthropogenic activities in the river the biological, chemical and physical characteristics of water have changed to a considerable extent. The objectives of this study were to find out the changes in physicochemical nature as well as biological health of river Ganga. Samples were analyzed on various physicochemical parameter i.e. Total Hardness, pH, B.O.D., and D.O. by using the standard methods and procedures. The result  shown that the average  pH -7.95, average, D.O.-2.91 mg/L, average B.O.D. -2.41 mg/L, average total hardness -114.72 mg/L. Microbial analysis was also conducted in terms of Most Probable Number [MPN] of total coliforms in the water sample and it shown the highest value for all samples. The presence and absence of the gas bubble in each tube were used to calculate an index known as the Most Probable Number.
Key-words- Ganga, Patna, Physicochemical, Microbial, Coliforms, MPN, D.O., B.O.D., Hardness, pH
