Designated Investigation Agency | Voluntary Soil Contamination Survey by Official Analysis | Geotech
Soil contamination investigation
We thoroughly track the history of past hazardous substance usage and identify underground contamination risks through strict sampling by the buyer and high-precision official analysis.
This is a technology-oriented buyer-side self-investigation solution that thoroughly identifies the residual risks of various specific hazardous substances that were used in the past at sites such as chemical plants and metal processing facilities, and completely clarifies the reality of underground contamination through the highest precision official analysis. Since soil contamination cannot be confirmed visually, the success or failure depends on how deeply the past operational realities can be traced. In this service, the "buyer-side historical investigation" meticulously analyzes the history of raw material usage, manufacturing processes, drainage system diagrams, and Safety Data Sheets (SDS) from the Showa era with professional scrutiny, listing all substances that pose risks without omission. The subsequent field investigation conducts a "voluntary Phase 2 sampling survey" using the most suitable construction method for the target substances, and precise analysis in milligram and microgram units is performed in the lab according to the official methods designated by the Ministry of the Environment. This approach minimizes the development risks of incurring enormous purification costs or project setbacks due to overlooked contamination after purchase, ensuring reliable safety.

Applications/Examples of results
Buyers involved in land acquisition and M&A in manufacturing industries such as chemical manufacturers and automotive parts factories, foreign developers with extremely strict environmental risk standards, and asset managers who want to completely clear the contamination history of land will implement this. When acquiring old industrial sites with complex operational histories, it is utilized as advanced due diligence to scrutinize potential residual risks of chemical substances that the seller cannot fully disclose, and to completely eliminate legal and economic risks related to future soil contamination.
