Project name: Water purification by Umbrella Grass
In 2015 and early 2016, there were a lot of mass fish deaths in Hanoi due pollution of water. According to a study of Vietnam Academy of Science and Technology in 2016, the arsenic and organic matters in water were four times higher than the permissible levels. The amount of ammonium was 2.5 times the allowable level and the surface water was also contaminated with E. coli and coliforms. We visited some lakes in Hanoi and found that most of them have contaminated water.
