Water Quality Assessment and Designated Best Use Determination of Ganga River, Kanpur

There exist different water sources on Earth’s surface like oceans, rivers, springs, lakes, and ponds, but not all of them are useable for all purposes. The current study’s primary goal is focused on the determination of DBU on the stretch of the Ganga River in Kanpur City, India. It was observed that sampling sites cannot be classified for any of the existing DBU conditions because of the high concentration of BOD which exceeds permissible limits for all of the DBU classifications. This implies that without treatment of the existing organic pollution in the selected stretch of study, the surface levels of the Ganga River are unsuitable for any practical use. The selected surface water stretches though unusable for any of the existing categories of DBU may be used for non-contact recreational purposes like boating, but suitable treatment is required for the selected stretch of study.
