With the Environment Club CCP group, I went to several water ecosystems in Hanoi to check the water quality and how it's related with locals' life.
The first one is 'To Lich' river. This river usually called as 'Toilet river' by foreigners who live in Hanoi.
We could easily observe that the polluted water from sewages directly flowed to the river, which is serious point pollution.
To get better result, I took 1 litre of water from the river. The smell of the river was very stinky and I could observe the air (bubble) being popped in the river. I think To Lich river is highly toxic.
The second one is Ngoc Khanh lake. It is near to my school and the civil government had huge project to clean the ecosystem of Ngoc Khanh lake. They took off all of the water in the lake and cleaned the lakebed. After the cleaning, they put lake water back. In result, this lake became so much cleaner than the past times.
Our CCP also took a liter of water from this water ecosystem as well. The water seemed much cleaner than the that of To Lich river.
We haven't taken any pictures from Giang Vo lake, but we also took a liter from Giang Vo lake as well. By observing the appearance, water of Giang Vo was quite similar to that of Ngoc Khanh.
On next Tuesday, we will investigate them to determine the turbidity of water ecosystem in Hanoi.
