Vedclass · Answer

(C) Sewage or municipal waste should not be directly passed into rivers,streams,and other water bodies because it contains human excreta and other organic waste,as well as a large number of pathogenic microbes.These wastes increase the Biological Oxygen Demand $(BOD)$ of the water body,leading to the death of aquatic organisms.Therefore,it is made less polluting by passing it through Sewage Treatment Plants $(STPs)$ before discharge.
