Measures for Soil Contamination

Water & Soil Soil and Groundwater Contamination Countermeasures Soil and Groundwater Contamination Countermeasures

Technology / Service Summary

Soil and groundwater contamination conditions differ depending on the compositions of heavy metals, volatile organic compounds, dioxins, oils and fats, and other contaminants. Efficient restoration requires total engineering technologies encompassing soil surveys and analyses; planning, implementation, and monitoring of countermeasures; and follow-up care, such as the formulation of proposals for empty lot utilization.

Purpose

Feature

Penta-Ocean offers total engineering services encompassing soil surveys through to follow-up care by applying its experience and technological capabilities backed by more than a century in operation.

1. Survey and planning
Site conditions are examined and appropriate plans are made according to the type of contaminant. After compiling this data from both general and detailed surveys, the scope of the restoration plan is then determined.

2. Restoration planning
Restoration work is carried out using the appropriate technologies for each situation and is employed to remove contaminants from the natural ecology of the area affected. Restoration technologies are roughly classified into a sealing type, which does not allow diffusion of contaminants to the exterior environment, and the cleansing type, which is used to either decompose or dispose of contaminants.
