Solidification/stabilization (S/S) technology is a well-established remediation technology for contaminated soil. In this paper, the contaminant types, remediation ingredients, and delivery methods related to this technology are described. S/S technology is applicable to both organic and inorganic pollutants. Portland cement materials and various additives are the widely applied remediation ingredients used in S/S processes. On the other hand, S/S technology is applicable not only to in situ process but also to ex situ process. What’s more, according to the Superfund Remedy Report of EPA, the application of S/S in soil remediation is introduced and analyzed. Finally, the need for further research and development of S/S is emphasized in order to overcome different challenges.
