Water quality analysis for the first stage of South-to-North Water Transfer East Line Project

Ninety per cent of conveyance channels in the first stage of the South-to-North Water Transfer East Line Project take use of the currently existing river channels. Owing to the conspicuous water environment problem, the quality of water transfer is closely related to the value of water resources and social economy development along the line of the project, and is also a determinant factor to the benefit of the project. Based on an analysis of the sources of water pollution and the quality of water environment in the affected areas of the project, the quality of water transfer was predicted according to the national planning for pollution remediation along the east line of the project, and some measures for water environment protection were discussed.
