Risk Assessment and Remediation of Cd-Contaminated Site

Based on early environmental investigation of the contaminated site, this paper conducts risk assessment for the particular Cd-contaminated site (S-block), acquires the remediation scope of contaminated soils and puts forward a corresponding remediation project accordingly, and then monitors and compares the Cd content before and after remediation. The results indicate that the risk assessment can reflect contamination distribution and contamination level of S-block, which provides a reliable basis for targeted remediation, and the monitoring results show that S-block has been remedied effectively.
