The major causes of water pollution in Dhaka include:
Rapid urbanization and industrial growth leading to decreased water quality1.
Inadequate sewage and inefficient waste management systems1.
Discharge of untreated industrial waste and household sewage into the river system1.
High levels of heavy metals such as chromium, lead, and iron, as well as chemicals like ammonia and phosphate in the water1.
Water logging due to environmental degradation, rapid population growth, and rapid industrialization2.
Pollution from agrochemicals, sewage water, storm runoff, solid waste dumping, oil spillage, sedimentation, and encroachment3.
A faulty distribution network of ageing pipelines and a poorly-managed sewerage system4.
Illegal encroachment of rivers, water bodies, land filling, and indiscriminate dumping of waste into rivers and canals5.
These factors contribute to the deterioration of water quality in Dhaka, posing a threat to public health and the environment.
