Designated Investigation Agency | Information on Soil Contamination Surveys and Risk Analysis for GS Land Transactions
Comprehensive support for soil contamination surveys necessary for the sale and purchase of former gas station sites! We clarify risks from historical site verification to sampling and residual soil measures.
When proceeding with the sale of land at a former gas station site, understanding the risks of soil contamination associated with past operations is an extremely important process. This proposal introduces a phased soil contamination investigation solution to avoid legal and economic risks during real estate transactions. It addresses specific hazardous substances unique to gas stations, such as benzene contained in gasoline, past tetraethyl lead, dichloromethane and trichloroethylene used in maintenance work, as well as boron and fluorine from car wash detergents and coolants, and heavy metals related to batteries. First, a historical investigation (Phase 1) will identify risk concern points based on the site's usage and equipment layout. Next, a sampling investigation of surface soil and soil gas (Phase 2) will be conducted to accurately measure the presence of contamination. If any exceedance of standard values is confirmed, we will transition to a detailed investigation (Phase 3) to determine the extent of contamination through deep boring and groundwater measurements. Additionally, we will provide consistent support up to the investigation of residual soil during building demolition, ensuring safe and secure land transactions.
basic information
This survey solution provides high-quality soil and groundwater investigation services by designated investigation agencies in compliance with the Soil Contamination Countermeasures Act. It is equipped with soil gas sampling and analysis equipment for gasoline components (such as benzene) and volatile organic compounds (VOCs), as well as surface and deep boring sampling devices. The analysis items can cover a wide range, including Type 1 specified harmful substances (such as dichloromethane), Type 2 heavy metals (such as lead and cadmium), and Type 3 pesticides and polychlorinated biphenyls. From on-site sampling to precise measurements at designated analysis agencies and the preparation of detailed reports, we implement a unified management system to provide reliable data.

Applications/Examples of results
It can be used for pre-risk assessments during the sale of land associated with the closure of gas stations, as well as for asset value calculations before sales contracts. It is also effective for confirming legal compliance with soil contamination countermeasures laws and municipal regulations related to changes in land ownership or redevelopment plans. Additionally, it is used for pre-disposal analysis of excavated soil (remaining soil) resulting from the removal of maintenance pits and underground tank groups. It is ideal for avoiding liability for defects and damage compensation risks after real estate transactions, thereby creating a highly transparent transaction environment for both buyers and sellers.
