Designated Investigation Agency | Comprehensive Survey to Determine Contamination Area from Historical Geography | Geotech
Soil contamination survey
Eliminate hidden defect risks in land transactions! A comprehensive investigation that addresses everything from the examination of usage history to soil gas analysis and the definitive determination of contamination scope.
In real estate transactions and land sales, the discovery of soil contamination after the handover poses the greatest business risk, leading to legal disputes and significant remediation costs. This comprehensive investigation service is a one-stop solution that scientifically and objectively proves the safety of land, enabling safe land transactions. First, in Phase 1, we conduct a usage history investigation by scrutinizing past public documents and land use history to comprehensively identify the handling records of hazardous substances. Next, for areas where contamination risk is a concern, we quickly carry out soil gas analysis and surface sampling as part of Phase 2 field investigations. Furthermore, if contamination is confirmed, we conduct detailed investigations to accurately determine the extent of contamination by tracing its depth and lateral spread. Based on strict public standards as a designated investigation agency, we report all processes as reliable evidence, making it ideal for supplementing important matter explanations and hedging risks in contracts. Geotech's solid technical capabilities will robustly protect the liquidity of your valuable real estate assets and enhance your social credibility.

basic information
This comprehensive survey is a standard process conducted by a designated investigation agency in full compliance with the Soil Contamination Countermeasures Act and the Ministry of the Environment guidelines. In Phase 1, the historical investigation examines closed registries, old topographic maps, aerial photographs, and administrative documents. In Phase 2, the overview survey conducts sampling at 10-meter or 30-meter grids, performing high-precision soil gas analysis targeting first-class specified harmful substances, as well as surface soil sampling for second-class and third-class harmful substances. The analysis is carried out at a registered measurement certification business based on Article 107 of the Measurement Act, measuring the leaching and content of each specified harmful substance. In Phase 3, the detailed investigation determines the three-dimensional extent of contamination through additional boring and creates accurate plans and cross-sectional diagrams.

Applications/Examples of results
It is utilized in real estate transactions, land acquisition for commercial sites and former factory sites, as well as in the evaluation of corporate assets associated with M&A. It is ideal for the preliminary extraction of hidden defect risks before residential land development or condominium projects, obtaining objective soil environment data for inclusion in important matters explanation documents, and for voluntary risk management by landowners prior to sale. By visualizing the timeline from historical land use to the determination of contamination scope before contracts are signed, it helps prevent disputes over damages after handover and enables negotiations for appropriate sale prices and the formulation of smooth development plans without delays. It can be used as reliable evidence by designated investigation agencies.
