Contaminated Site Diagnosis & Evaluation
Phase I of the soil environmental assessment identifies the potential for contamination at the target site and adjacent sites.
| Site History & Overview Investigation | Review of documents, drawings, figures, records, etc. (current and historical) |
| Site Visit Survey | Verification of contamination discharge, location of contaminating substances, storage conditions, topography and geological conditions of target site and surroundings, facility status, and suspected contamination situations |
| Stakeholder Interviews | Interviews with site managers, nearby residents, responsible officials, etc. |
This phase confirms contamination at suspected contamination points and hazardous substance leakage areas identified in Phase I.
| Preliminary Investigation Review | Procedure to confirm contamination based on Phase I data |
| Sample Collection | Collection of samples from potentially high contamination concentration points |
| Field Sample Screening | Determination of contamination level using screening equipment |
| Sample Analysis | QA/QC for accurate and reliable detection of contaminants |
Remediation Investigation / Feasibility Studies
Based on Phase II results, this phase verifies optimal remediation technologies, predicts efficiency, and evaluates key design parameters needed for the remediation plan.
| Work Plan Development | Selection of sample collection points and implementation methods, presentation of theoretical basis for QA/QC methods |
| Remediation Investigation | Presentation of remediation alternatives through modeling tailored to geological and environmental characteristics |
| Applicability Assessment | Selection of suitable remediation alternatives appropriate for site characteristics and performance evaluation |
