Water pollution directly affects the living environment of human beings and damages human health. A variety of pathogenic bacteria, viruses and parasites spread through polluted water, causing some infectious diseases in some areas and even causing local epidemics.
Water pollution also seriously threatens the safety of drinking water sources. At present, it is increasingly difficult to choose a water source that meets the drinking water sanitation standard in urban areas. According to preliminary statistics, there are nearly 500 water intakes along the main stream of the Yangtze River, all of which are affected to varying degrees by coastal pollution zones. If all of them take water from the middle of the river, it will require billions of yuan more than the original investment.
