| Water is a very important resource, especially for human life. The incident that occurred on October 9, 2019, is a serious warning about water security. The unconscious of some people, pouring waste oil into the Dam Bai lake area. Accordingly, waste oil mixed into water sources, polluting clean water sources, affecting hundreds of thousands of people in Hanoi. The awkwardness of managers when having water pollution. Especially inexperienced in dealing with incidents. Practical survey results, combined with topographic analysis of Dam Bai lake area (Phu Minh commune, Ky Son district, Hoa Binh province), where the Song Da water plant takes water directly to process into clean water for about 250,000,000 people of Hanoi Capital. The author concludes: There is no way to separate the spring water sources with Da river water. The water safety corridor is compromised. The problem of waste oil polluting the Tram spring stream flowing into Dam Bai lake, polluting the Da river water source, is a warning sign for many incidents of water source insecurity that are likely to occur in the future. |
