Water pollution has been a serious problem in every part of the world and Vietnam is not an exception. According to the director of the Hà Nội-based Centre for Community and Environment Research, rapid urbanisation and industrialisation were generating more and more pollutants, and the water environment had been badly hit especially in big cities such as Hanoi, Ho Chi Minh and Danang. In Hanoi, 80 percent of water used for daily activities became wastewater, making the region the largest wastewater discharger in the country. This leads to a lot of problems related to people's health and life and air quality. Water pollution is still a major challenge for the region and the country. There have been a number of solutions and plans to solve this matter. Other experts have called for a comprehensive, thorough plan to dredge and clean polluted rivers and canals, improve wastewater treatment works, upgrade urban sewage systems and drastically limit the exploitation and use of underground water.
