“…Several similar studies related to the assessment of water quality and bacterial contamination in river During the study period, DO was found minimum in the summer season. Similar patterns were shown by various researchers (Khanna and Bhutiani 2003;Singh et al 2006). In aquatic systems decrease in DO values during summer is due to increased temperature (Naz and Turkmen 2005).…”

Yamuna River water in Agra city of India is heavily contaminated with toxic pollutants, including heavy metals that cause severe damage to ecological and social aspects of life. At present, the direct use of river water for drinking purposes cause severe hazards due to anthropogenic activities and environmental pollution. The quality assessments in terms of physical, chemical, and biological attributes of water samples are essential to understand their impact on humans. In the present study, Yamuna River water samples were collected from three different sites in Agra city during the monsoon, summer, and winter seasons. Various physico-chemical parameters were estimated, and the concentration of heavy metals was measured. In the case of physico-chemical parameter characterization, the values found were mostly above the permissible limits. The results suggest that the Yamuna River water samples contain high levels of cadmium, chromium, lead, and nickel above the desirable levels in most cases. The water samples were subjected to metagenomic analysis using the Illumina platform, which revealed that Proteobacteria, Bacteroidetes, Verrucomicrobia, Actinobacteria, and Planctobacteria were the most abundant phyla with a relative abundance of 61%, 9.34%, 5.23%, 4.64%, and 4.3%, respectively. The Comamonadaceae was the most abundant family, which consists of the genera involved in hydrogen oxidation, iron reduction, degraders of polycyclic aromatic hydrocarbons, and fermentation. Functional prediction showed the presence of genes responsible for different metabolic pathways. The study concludes the status of water contamination at three different sites in Agra and suggests the futuristic use of this research in the eld of bioremediation.

Bacterial community has always been an essential component of aquatic ecosystem because of the important role played by it in maintaining continuity of ecosystem. Aquatic bacterial diversity has been an interesting, popular and wide area of research as it is well correlated with the level of pollution in the ecosystem. Addition of pollutants is one of the major factor which disturbs bacterial diversity and density in river. The aim of the present work is to investigate the presence of bacteria and analyze its correlation with pollution status in river Kshipra which is considered to be a holy river of central India. The study also records the occurrence of different bacterial species including fecal coliform, total coliforms and many other pathogenic bacteria. Presence of pathogenic bacteria like Salmonella sps., Pseudomonas sps. ,Shigella sps., Vibrio sps. and FC/FS ratio between 1.1-1.5 indicates that the river is contaminated by domestic and city sewage as well as by both animal and human excreta. The current investigation reports the occurrence of different water borne diseases like typhoid, cholera, gastrointestinal diseases and skin infections etc in people residing nearby river who consume river water for fulfilling their daily need. A strong correlation has been established between bacterial density and physicochemical parameters like temperature, Dissolved Oxygen, Biological Oxygen Demand and Chemical Oxygen Demand. Urgent measures should be taken by eminent authorities to minimize the anthropogenic activities like dumping of flower, oil, body ashes, coconut shell in order to restore this sacred river.
