According to the requirements of the "Law of the People's Republic of China on the Prevention and Control of Soil Contamination", soil pollution status investigations shall be conducted as required for plots where the land use is changed to residential, public management, and public service land; for production and operation land of key soil pollution supervision units where the land use is changed or the land use right is taken back or transferred; and for construction land plots where soil pollution surveys, detailed surveys, monitoring, and on-site inspections indicate soil pollution risks. Through a systematic approach to investigate whether a plot is contaminated, as well as the extent and scope of contamination, this process provides a basis for soil risk management and remediation.
