Health Desk—July 30, 2017: Nearly 90 percent wastes directly mix in water causing pollution in developing countries, a new survey revealed.
"Releasing of wastes is one of the major causes of water pollution. These wastes are directly mixing in sources of water causing pollution," Stamford University Vice-Chancellor Prof M Feroze Ahmed said while presenting a keynote paper at a technical session of the two-day "Dhaka Water Conference-2017" at a city hotel on Saturday.
Water expert Professor Ainun Nishat chaired the session while foreign representatives also joined it.
In his keynote paper, Prof Ahmed said the refinement rate of wastewater is only 10 percent.
"If the refinement rate of wastewater can be upgraded up to 50 percent then the water pollution will come down to a tolerable level," he said, adding that excessive use of water also increase the rate of pollution.
The vice-chancellor recommended for ensuring 100 percent sanitation by stopping defecation in open spaces.
In the first day of the conference, different recommendations were made including ensuring safe water, sanitation, reducing water pollution, developing quality of water, using moderate water and minimizing the crisis of drinking water and taking up integrated water management.
