Story of a Black River
the documentary is based on Turag River.The Turag river is one of the most important river around Dhaka city. Many industries have set up in and around the Dhaka City during last decade, and the number of new industries are continually increasing. The river Turag have been steadily experiencing complicated problems like pollution and encroachment that have almost suffocated these valuable lifelines of the city. The highest pollution points of the Turag River include the Buriganga Turag Bridge area at Bashila and the Tongi Bridge area. At these two points, the river water is pitch black with the worst of smell and can be used for hardly any purpose. The other extreme pollution spot is near the Tongi Bridge that derives massive pollutant loading from the Tongi Industrial Area. This industrial area possesses about 29 heavy industries. This cluster of industries of the capital city generates a lot of effluents daily, which contain lots of heavy metal. There are some severe pollution hampering the natural properties of the river and gradually degrading the environmental condition of the whole area.
