Soil contamination investigation: Early investigation is essential for operating factories.

basic information

Our soil contamination investigation will be conducted as a "designated investigation agency" under the Soil Contamination Countermeasures Act, using highly reliable and certain technical specifications. First, we will conduct a "historical investigation (Phase 1)" to thoroughly analyze past land use conditions using information such as residential maps and registration records, and assess the possibility of contamination. Based on these results, we will transition to a "soil overview investigation (Phase 2)" where we will sample and analyze the actual soil on-site to scientifically confirm the presence or absence of contamination. In particular, when the excavation area of a building is long in the direction of extension, we will implement a flat consideration where five sampling points are treated as one sample. In cases where the excavation depth exceeds 5 meters, we will adopt specifications that increase the number of samples by dividing them in the depth direction to prevent overlooking of contaminated soil, as well as specifications that combine prior sample collection through boring. This approach will thoroughly eliminate the risks associated with simple investigations limited to near the surface and guarantee high-precision data that fully meets disposal and administrative standards.

Applications/Examples of results

Specific Procedures 1. Inquiry and Consultation: We will ask about the factory's operating conditions, future plans for rebuilding or closure, and past operational history to design the optimal investigation and analysis plan. 2. Historical Investigation (Phase 1): We will examine past land use based on objective information such as residential maps and registration records, narrowing down areas with potential soil contamination risks. 3. Sampling Plan Development: Based on the site area and excavation depth (e.g., over 5m), we will establish appropriate sampling points, including boring, to comply with environmental regulations and prevent overlooking subsurface contamination. 4. Soil Overview Investigation (Phase 2) and On-site Sampling: We will properly collect soil samples from the site. 5. Laboratory Analysis and Confirmation of Contamination: We will conduct precise analysis of the collected samples in the lab to accurately investigate and confirm the presence of harmful substances and their levels against regulatory standards. 6. Cost Estimation and Countermeasure Planning: In the event that contamination is confirmed, we will estimate and plan countermeasure costs with a focus on continuing or preventing the expansion of factory operations, leading to a safe handover or rebuilding.
