The present investigation is an attempt to isolate and characterize the bacterial diversity of important water bodies of Golaghat District. The water bodies include one wetland (Rogajan beel), one hot water spring (Gorompani hotspring), one cemented pond (Aathkhilia Namghar pond) and D. R. College pond. Bacterial diversity in water samples of all the waterbodies was found to be very less and most isolates were pathogenic. The water samples were slightly basic in nature but the soil of Golaghat

INTRODUCTION Water is an indispensable part of life. Water pollution and desertification creates inhabitable conditions not only for humans but also aquatic and other terrestrial living organisms. It also influences the microbial diversity of the water body (pond, wetland, river, lake, spring etc). The microbial community plays a vital role in controlling water pollution by bio-degradation and the process of detoxification. Sometimes it causes pollution by releasing toxic substances and sometimes behaving as pathogen itself. Microbial diversity is governed by a number of abiotic and biotic factors and other external agents such as industrial and domestic wastes and other chemical pollutants (insecticides, pesticides, fertilizers and minerals etc). Site Preparation and Location-Water samples were collected from some selected water bodies of Golaghat district. This includes the Aathkhilia Namghar pond which hosts different species of fishes and tortoises, Rongajan beel (wetland), Perennial pond (D. R. College campus) and cemented hot water spring pond (Gorompani) of Nambor wildlife sanctuary.
