Abstract

Cadmium is a class 1 carcinogen classified by the International Agency for Research on Cancer (IARC) and has a high potential for leaching into groundwater. Therefore, it is necessary to address cadmium contamination by employing adequate treatment methodologies. Although various methods have been suggested to reduce cadmium in groundwater, their applications often suffer from various limitation arising from heterogeneous field conditions and technical difficulties. In this work, several in-situ technologies to treat cadmium contaminated groundwater were reviewed and discussed by separately addressing physicochemical, chemical and biological methods. In particular, the optimum cadmium remediation strategies that involve physical removal of source area → physicochemical and chemical remediation → biological remediation were proposed by considering reduction efficiency, adsorption rate, economic feasibility and ease of field application in groundwater.
