GeoTech Co., Ltd. conducts a seamless investigation as a designated investigation agency, including a historical survey (Phase 1) tailored to the demolition and excavation plans, an overview survey (Phase 2) suitable for narrow sites and existing buildings, and a detailed survey (Phase 3) to determine the extent of contamination. Additionally, we perform rapid soil analysis that complies with local waste regulations and disposal site acceptance standards, thoroughly supporting the separation and proper disposal of contaminated soil. By providing reliable evidence through preliminary investigations, we prevent interruptions in construction, ensuring adherence to timelines and significant cost optimization.

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.

Soil contamination surveys during the sale of gas station land are essential procedures for compliance with the Soil Contamination Countermeasures Act and local government ordinances, as well as for preventing future legal liability risks. Our service, designated as a survey organization by the Ministry of the Environment, accurately and smoothly evaluates and visualizes the specific risks of hazardous chemicals associated with fueling stations. We can conduct comprehensive surveys covering gasoline components such as benzene, past additives like tetraethyl lead and 1,2-dichloroethane, as well as degreasers used in maintenance processes like dichloromethane and trichloroethylene, and contaminants from car wash detergents and refrigerants such as boron and fluorine, along with lead and cadmium related to batteries. After establishing risk areas in the first phase of historical investigation, we conduct soil gas and surface sampling in the second phase to assess the actual contamination. If necessary, we perform deep boring investigations and groundwater monitoring in the third phase to determine the three-dimensional extent of the contamination. Furthermore, we provide consistent support for the proper treatment analysis of demolition soil, strongly backing compliance with laws and facilitating smooth real estate transactions.

To smoothly complete the redevelopment of former gas station sites and land transactions, a planned soil contamination survey that aligns with the development process is essential. Our company provides one-stop support as a designated investigation agency, from historical surveys to detailed analysis, consideration of countermeasures, and confirmation of soil disposal. We can address a wide range of hazardous substances, including benzene from the refueling process, past tetraethyl lead and 1,2-dichloroethane, dichloromethane and trichloroethylene from maintenance pits, boron and fluorine from car wash and rust prevention agents, as well as lead, cadmium, arsenic, and selenium associated with electrical components and batteries. After identifying risk areas in Phase 1 historical surveys, we conduct soil gas and surface sampling in Phase 2 to quickly determine the presence of contamination. If contamination is confirmed, we establish the three-dimensional extent of contamination through boring investigations in Phase 3 and propose optimal countermeasure methods according to the redevelopment budget. Including soil analysis during removal work, we comprehensively support the success of business transformation.
