To Lich River is a small river, flowing from Cau Giay district, through 6 districts of Hanoi and emptying into Nhue River. Legend has it that the river was named after a god named To Lich, who lived during the Tan Dynasty in Giao Chi. As an outline of the ancient Thang Long capital, To Lich river is an edge of the Thang Long water quadrangle, also a tributary of the former Red River. According to the old people, in the old days, the river water was clear, fish and shrimp grew a lot, people could take a boat on the river to admire the scenery.
The beautiful To Lich River before suffering from pollution. According to statistics of the Hanoi Department of Natural Resources and Environment, currently, on average, the To Lich River has to receive about 150,000 m of industrial and domestic wastewater every day and night, which is poured directly into the river through more than 300 culverts. waste discharge. Besides, there is still the situation of littering the river, causing heavy environmental pollution and loss of urban beauty. Such pollution occurs not only in To Lich river, but also in many other rivers and lakes of the capital. The pollution of the river has greatly affected the daily life of people living along the river, adversely affecting the flora and fauna in the river, in addition, water pollution has indirectly affected the health of the river. people through agricultural production in some regions. The government has come up with a number of solutions to limit pollution, but it is still not feasible. Any solution for To Lich river? According to Japanese experts, in order to "revive" the To Lich River, it is necessary to have a total solution to solve all problems such as: wastewater collection, thoroughly treating the source of the stench, treatment of the bottom mud layer, treatment of contaminated water in the river bed, etc. Over the past time, the Hanoi city government has implemented many solutions but it is not feasible because they have not completely solved the root cause of the water pollution of the To Lich river. In addition, solutions also require synchronization, concentricity and synergy from three sides: managers - investors - scientists. |

Hello Nam Phuong, this is your mentor Chelwoon.
I have one Vietnamese friend. When we talked about her local region, she used to occasionally talk about the deterioration of some of her country??s famous beautiful sites like the Mekong River. ¡®To Lich River?? is a ¡®tributary??, so it seems to be more vulnerable to the pollutants, though pollutants do not flow into the coastal surrounding area. In this regard, The Hanoi city government have to find out more feasible solutions as soon as possible. I hope that younger generation could experience the joy and happiness that the older generation had experienced.
Thank you for the article!
Regards,
Chelwoon

Hello Nam Phuong, this is your mentor Joon.
Thanks for sharing stories from your local region. There are different places around the world suffering from water pollution. The solution is quite simple, but hard at the same time: to remove all causes of pollution. Industrial wastewater should be purified before it is released, sufficient and proper sewage system should be implemented and so on. However, it is really hard to implement all the required infrastructure and regulations at once. We should take small steps continuously so that we could reach our goal before it is too late.
Well read your article, and let's keep up!
Best,
Joon
