Water pollution is one of the most significant problem in Vietnam. Water pollution comes from a variety of sources, including agricultural activities, industrial discharges, and the dumping of untreated sewage. Pesticides, fertilizers, and other chemicals used in agriculture can contaminate the water supply, as can the release of toxic chemicals from industrial facilities. In addition, inadequate treatment of sewage can lead to the release of contaminants into the water. Therefore, Water pollution leads to serious illness and diseases for human health. It can also harm the environment, as it can affect the health of aquatic ecosystems and the animals that depend on them. Some methods to decrease water pollution in Vietnam include the implementation of stricter regulations and the development of better wastewater treatment systems.
