Soil Pollution and Remediation

A Study on Location-Based Priority of Soil and Groundwater Pollution Remediation

Under the circumstances of limited government funds, the future pollution remediation policies and practical implementation may need contemplation from the perspective of maximized efficacy, in order to pursue the most effective resource allocation. In fact, different pollution sources and types affect the value of surrounding properties differently in significance and scope. Therefore, benefit...

Heavy Metal Pollution of Soil and a New Approach to Its Remediation: Research Experiences in Japan

Rapid industrialization in the 1960s caused heavy metals such as cadmium (Cd) to severely pollute soil in Japan. The Agricultural Land Soil Pollution Prevention Law was enacted in 1970 to cope with the heavy metal pollution. Cd, in particular, has been recognized as one of the most detrimental elements in Japan because of the so-called “itai-itai” disease caused through Cd uptake. Recently, the...

Steam Injection for Soil and Aquifer Remediation

Innovative technologies for subsurface remediation, including in situ techniques based on heating the subsurface to enhance the recovery of organic contaminants, are increasingly being evaluated for use at specific sites as the limitations to the conventionally-used techniques are recognized. The purpose of this Issue Paper is to provide to those involved in assessing remediation technologies f...

Soil Contamination, Risk Assessment and Remediation

Biochar for soil remediation and land reclamation

Land reclamation generally relates to the improvement of soils degraded by human activities, for example construction and certain forms of agriculture. Soil remediation refers to the process of removing, neutralizing or reducing the toxicity of certain compounds, often left by human activities such as mining and industry. Each degraded and/or contaminated site is potentially unique in its chara...
