Abstract: Environmental monitoring plays an important supporting and guaranteeing role in the safe utilization of sites after their remediation and risk management. However, research on the relevant environmental monitoring system is limited in China. This study focuses on analyzing the current difficulties and issues in post-management environmental monitoring. It conducts research and discussion from the aspects of environmental element identification, monitoring plan formulation, sample collection, and result analysis, preliminarily establishing a framework and procedure for the environmental monitoring system. Taking a legacy coking plant site as an example, a monitoring scheme is designed, aiming to provide a technical reference for the post-management of remediated and risk-controlled sites in China.
