Soil contamination survey
Even in narrow urban areas and operating factories, we do not stop buildings or production! We respond in stages from usage history surveys to soil gas analysis and accurate determination of contamination areas.
Delaying the confirmation of soil contamination risks due to the inability of large boring machinery to access narrow plots adjacent to commercial and residential areas in the city center, as well as sites of currently operating production factories, is an extremely dangerous management decision that could lead to delays in future rebuilding and a collapse in asset value. Our comprehensive investigation service is a specialized solution that completely clears such spatial and practical constraints and thoroughly optimizes investigation costs through a phased approach. First, in Phase 1, the usage history investigation meticulously examines old maps and equipment layout diagrams to identify pinpoint areas where risks are genuinely concerning. In the next Phase 2, on-site sampling utilizes compact manual and portable equipment that does not interfere with operating lines, allowing for rapid and high-precision soil gas analysis and surface sampling. Furthermore, even in cases of contamination exceedance, accurate determination of the contamination range is achieved through small-scale drilling technology suitable for narrow plots, keeping the often excessive remediation costs to a necessary minimum. With professional and flexible on-site responsiveness, we will protect your valuable land assets.
Inquire About This Product
basic information
This comprehensive survey is a flexible technical specification that completely complies with the Soil Contamination Countermeasures Act, eliminating site constraints to the utmost extent. In Phase 1, the historical survey pinpointed areas of concern using closed registries and records of facility changes at factories. In Phase 2, general sampling will employ portable and lightweight samplers with a width of 80 centimeters or less to conduct high-precision soil gas analysis for the rapid detection of volatile harmful substances. In Phase 3, detailed investigations will involve layered drilling at different depths using low-head drilling machines to create an accurate three-dimensional contamination range map and present minimal countermeasure proposals based on objective facts.

Applications/Examples of results
It will be utilized for voluntary environmental risk inventory and cost management in the planned redevelopment sites of buildings and condominiums in urban areas, operational sites of plating and cleaning factories, and small land transactions such as gas stations and automobile maintenance shops. By gradually advancing steps from historical analysis to soil gas analysis and determining the extent of contamination while fully maintaining production activities and store operations, it prevents the deterioration into sudden large-scale contamination. It is ideal for practical applications that achieve compliance with regulations and eliminate defect risks through minimal remedial construction based on assessment data, completely avoiding unnecessary full excavation and maximizing site defense effectiveness within limited budgets and spaces.
