Controlling River pollution
Generally, our rivers are being polluted by the discharge of untreated industrial effluents and urban wastewater, agrochemicals, sewage water, storm runoff, solid waste dumping, oil spillage, sedimentation and encroachment. The water quality also depends on effluent types and discharge quantity from different types of industries, types of agrochemicals used in agriculture, and seasonal water flow and dilution capability of the river system.
Buriganga is a typical example of serious surface water pollution in our country. In the present situation this river carries wastewater during the months of November to April ( the dry season), becoming toxic. The level of pollution is so high that no aquatic species can survive in it and the situation is getting worse day by day.
As we would all agree, the time has come to take action to protect our rivers from further degradation, and before nature takes revenge on us.
