Abstract
In situ solidification/stabilization (S/S) possesses many advantages compared to other soil remediation technologies such as cost-effectiveness, high operational versatility, and the capability of treating various contaminants. The long-term effectiveness is crucial due to that contaminants remain underground, being exposed to various environmental stresses that may potentially degrade the S/S materials. This chapter reviews the immobilization and leaching mechanisms of contaminants in S/S, which would evolve over time and be affected by numerous factors including the intrinsic properties of materials and environmental conditions. Common methods and models of evaluating/predicting the long-term effectiveness of S/S materials are discussed regarding their applicability and limitations. Importantly, field studies on in situ S/S applications where detailed analyses of the materials exposed to the site conditions for over 1 year were summarized to validate its real-world long-term effectiveness. It is concluded that generally in situ S/S treatment is effective in treating contaminated soils with complex nature for many years. Finally, insights are provided on improving the long-term performance and sustainability of in situ S/S and better assessment methodology. It is hoped that the information presented in this chapter could improve our understanding and facilitate further cross-disciplinary research activities on the long-term performance of in situ S/S.
