Physiochemical and microbiological study of river water of ganga and yamuna in allahabad

Ganga and Yamuna are two main rivers of north India and the area around them is the fertile Indo-Gangetic plain. Yamuna merges into Ganga at Triveni Sangam in Allahabad. During festival season people take a holy dip in the Ganga river and Sangam and also use it for drinking. Sangam is the site for the Kumbh Mela every twelve years, Ardh Kumbh Mela every six years and Magh Mela every year. Various sources of pollution make the water of these rivers unfit for human consumption. This study was carried out in Allahabad to assess the quality of water of these rivers before and after the Magh Mela. Different physicochemical parameter like pH, turbidity, DO, BOD, COD, and TDS were assessed. These were found to be above the permissible limits. Various pathogenic microorganisms were isolated from these rivers water. Thus the water of these rivers Ganga and Yamuna was found to be unfit for human consumption without treatment.
