Designated Research Institution | Comprehensive Environmental Survey with Precise Sampling | Geotech

Fully utilizing advanced sampling techniques and soil gas analysis! A high-precision comprehensive environmental survey that leads from usage history investigation to the determination of a three-dimensional contamination range.

In the practical measures for soil contamination countermeasures, inappropriate sampling and ambiguous measurement bases can lead to significant oversights in contamination or generate excessive remediation costs, becoming serious factors that can jeopardize business plans. This comprehensive investigation service is a high-precision solution that leads to the accurate determination of contamination areas by obtaining objective data that fully meets scientific standards, based on reliable analytical techniques as a designated investigation agency. In Phase 1, the usage history investigation thoroughly examines materials such as registration history and administrative documents to accurately identify the historical material risks of the land. In the subsequent Phase 2 field investigation, high-precision soil gas analysis is reliably implemented as a countermeasure against designated hazardous substances, and the underground conditions are precisely quantified through strict sampling practices in accordance with measurement laws. Even in the unlikely event that standard exceedances are detected, accurate three-dimensional determination of contamination areas is achieved by conducting depth-specific sampling through detailed boring, minimizing the volume of remediation materials, thereby optimizing the budget and ensuring compliance at a high level.

basic information

This comprehensive survey is based on the highest standards of precision sampling specifications under the Measurement Act and the Soil Contamination Countermeasures Act. In Phase 1, we thoroughly verify old maps, land use history, and administrative chemical substance handling notifications. In Phase 2, a general survey will be conducted using high-precision soil gas analysis to capture trace amounts of volatile organic compounds, along with surface soil sampling based on specified standards. In Phase 3, detailed investigations will involve depth-specific sampling boreholes for oil content and heavy metals, followed by analytical measurements that comply with Ministry of the Environment standards, resulting in highly accurate data for determining contamination ranges with minimal error, as well as the creation and delivery of three-dimensional contamination maps.

Applications/Examples of results

It is used for voluntary defect risk assessment before land transactions, environmental due diligence in the redevelopment of sites such as precision machinery factories and chemical plants, and legal procedures to ensure full compliance with municipal environmental regulations. By scientifically advancing from the stage of historical investigation to sampling, soil gas analysis, and determining the extent of contamination, it prevents disputes after handover and unexpected troubles during excavation work. It is ideal for situations that require extremely high reliability as objective design data to minimize countermeasure costs or as strong evidence of environmental safety for neighboring residents and investors.
