Water pollution is water that pollutes the environment where the use-value of water is lost due to chemical substances. Human activities will cause a large amount of industrial, agricultural, and domestic waste to be discharged into the water, causing the water to be polluted. Increasing water pollution has posed a major threat to human survival and safety, and has become a major obstacle to human health, economic and socially sustainable development.
