The relevant person in charge of the Municipal Ecological Environment Bureau said that since the beginning of this year, the city has strengthened the source control and implemented monitoring and analysis of water quality and water storage using various hydrological research instruments through satellite remote sensing, drone inspection and manual on-site review. The "one map" of the basic conditions of the key rivers and the investigation of the problems will be presented, and the delivery orders will be promoted one by one to solve the problem of water pollution prevention and centralized treatment of key industries. The counties and districts have further strengthened water environment management, and the quality of urban surface water has increased significantly.
