Track the history of past hazardous substances and clarify underground contamination risks through official analysis.

In the chemical industry, managing the risks of soil contamination from past hazardous substance usage is crucial. Particularly in transactions involving sites like former factories, underground contamination that cannot be visually confirmed may lead to significant risks such as cleanup costs and development delays after purchase. To prevent these risks in advance and ensure safe business operations, specialized investigations and high-precision analyses are essential. GeoTech's "Designated Investigation Agency | Voluntary Soil Contamination Survey through Official Analysis" provides thorough risk assessments and reliable safety guarantees from the buyer's perspective to address these challenges. 【Usage Scenarios】 - Transactions involving former chemical plants, metal processing plants, etc. - Identification of contamination risks based on past operational realities - Reduction of development risks for buyers 【Benefits of Implementation】 - Mitigation of cleanup damages and risks of development setbacks after purchase - Ensured safety through understanding the realities of underground contamination - Issuance of highly reliable measurement certificates

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 the land will implement this. When acquiring old industrial sites with complex operational histories, it is utilized as advanced due diligence to scrutinize the potential residual risks of chemicals that the seller cannot fully disclose and to completely eliminate legal and economic risks related to future soil contamination.
