A technology that investigates and monitors the degree of contamination of soil and groundwater, and its changes over time.
A technology that removes contaminated soil by excavation or dredging under secured conditions.
A technology that prevents leaching of heavy metals from soil to water with the use of insolubilization chemicals or solidification agents.
| Soil Washing | A technology that washes and removes heavy metals and volatile organic substances contained in soil with chemicals, etc. |
|---|---|
| Heating Separation | A technology that separates and removes heavy metals, volatile organic substances, etc. from soil by heating up the soil that contains such substances. |
| Electrochemical Separation | A technology that separates and removes contaminants such as heavy metals, etc. from soil by flowing electric current through the soil. |
| Flotation Separation | A technology that lowers the specific gravity of contaminants and separates them by adding chemicals and blowing air into the contaminated groundwater. |
