Contaminated Soil Remediation

Soil Remediation Process

1. Site Investigation

2. Basic Remediation Design

Analysis on physicochemical characteristics of contaminated soil in the field
Selection of soil medial method by contaminants
Contaminants Heavy metals Oil PesticidesContent of fine soil particles (paddy soil, etc.)
