The present were a systematic analysis of sediment contamination by heavy metals of the River Ganga at nearby Allahabad city. To estimate the sediment transport of the river, seven heavy metals, namely Co, Cu, Cr, Ni, Cd, Zn, and Pb were examined from the freshly deposited river bed sediment on a seasonal basis for the assessment of fluctuation for two consecutive years 2014–2015 and 2015-2016. In the water of the river channel maximum value of Co, Cu, Cr, Ni, Cd, Zn, Pb and was recorded as 0.027, 0.032, 0.007, 0.018, 0.043, 0.031and 0.019 mg/l, respectively whereas the minimum value was recorded 0.005, 0.016, 0.001,0.005, 0.003, 0.013, 0.005 mg/l, respectively at different sites. Most of the above values were found either below or closed the permissible limit. Correlation analysis among all considered heavy metals shows positive correlation with each other in both the years. The data generated may provide useful information to Governmental agencies to control the heavy metal pollution of the river at these urban centers which may even be worst in future scenario. The present experimental data indicates that the pollution level along the river Ganga is not very high but the increasing population load and untreated sewage influx in the channel may cause irreparable ecological harm. The highest contamination degree of the sediment (potency) was noticed and marked have also adverse affects on freshwater geo-ecology of the river.
