abstract
Due to Novel Corona Virus (COVID-19 Pandemic), all types of industries, vehicles anthropogenic activities suddenly shut off for months. As a result, the surface water quality of water bodies greatly reduced in terms of SPM(Suspended Particulate Matter). An investigation was done to find out the surface water quality of river Ganga at Buxar, Bihar. During investigation, the surface water quality of river Ganga was examined at various sites which stretches to a distance of 8 km covering the length of the river from Central Jail, Buxar upto the village Sarimpur. The result conclude that the surface water quality of river Ganga is improved during lock down period. This occurs because of the decreasement in the percentage of SPM. As a result, the pollution level of the water of this river also decreases and hence the water quality of river Ganga become more suitable for the growth of aquatic life at this site.
