Four of the rivers surrounding Dhaka—Buriganaga, Sitalakhya, Balu and Turag—are so polluted that they have been declared as ecologically critical areas in 2009 by the Department of Environment. This makes them unsuitable for any human use. Nevertheless, people living in low-income and slum areas still have a lot of direct contact with river water, exposing them to health risks. They use river water for dish washing, laundry, cleaning fish and vegetables, and personal washing, washing and dyeing denim, washing fish baskets or plastic sheets, collecting plastic waste and fishing. As a result, many of the immediate environmental burdens of river pollution are borne by these low-income residents.
