Buriganga water shows slight improvement

The quality of Buriganga water has improved slightly following the relocation of tanneries to Savar from the city's Hazaribagh area and heavy rainfall this year, reports UNB. But experts think a lot more things, including checking other industrial and domestic wastes, need to be done to fully revive the water quality of this important river. They also said the government should now take strong measures to shift the dyeing factories located at Shyampur on the bank of the river to another place as those have become a major threat to it after the ternary relocation with the discharging of high level of concentrated dyes, chemicals, and heavy metals directly into the Buriganga through the hidden pipelines.

Talking to UNB, water experts Prof Ainun Nishat and Buet Prof Md Mujibur Rahman and green activists Poribesh Bachao Andolon (Poba) chairman Abu Naser Khan and Bangladesh Paribesh Andolan (Bapa) general secretary MA Matin also said it is not possible to fully improve the water quality of the Buriganga without preventing pollution by other industries, Dhaka Wasa and city corporation.

The tests conducted by the Department of Environment (DoE) show that the water quality of the river improved as it found the level of average dissolve oxygen (DO) in its water was 2.3 mg/L at Sadarghat point in November compared to 0.00 mg/Lin January last year.

The DoE also found the level of BOD (biochemical oxygen demand) 2.6mg per litre during the same period against 11.5mg in January last year.

Contacted, Prof Ainun Nishat said it appears that the government has made some progress in reducing pollution in the Buriganga as the colour of its water has changed significantly. "It'll be clearly known whether the water quality has improved or not during the January-February period."

He said the tannery relocation, rainwater and the flow of freshwater from the Jamuna River into the Buriganga during the rainy season are the major reasons behind the improvement of water in the highly-polluted river.
