River polluted around the capital has reached such a level that the groundwater system where the aquifers are recharges from the riverbeds is being contaminated. A recent study shows. In the six month from November to April virtually no water but only stinky mucky liquid flows in the gradually in the narrowing rivers- the Buriganga, Shitalakshya,Turag, and Balu as no government could stop discharge of liquid waste into them.
A recent study jointly done by the World Bank and the Institute of Water Modelling ( IWM) says. The ground water system is being contaminated in areas where aquifers are recharged from the riverbeds. The pollution is creeping towards the central part of Dhaka city within time.
