Phase 2: General condition survey and Detailed survey

We will perform a general condition survey and a detailed survey based on the "Soil Contamination Countermeasures Law", and also analysis for countermeasures plan.

General condition survey

We will survey a contaminated condition of a surface layer of a soil. When there is contamination in the surface layer of the soil, we will perform drilling survey in this part.

Detailed survey

In order to decide a countermeasures, we will three-dimensionally grasp a plane range and a depth of the contamination soil (a range in the depth direction), and a groundwater contaminated condition.

Groundwater flow analysis

Based on the detailed search, we will three-dimensionally grasp a stratum and a contaminated condition, and reproduce a groundwater flow by a numerical analysis.
