Abstract: Chlorinated hydrocarbons are widely used as important chemical raw materials. However, the leakage during the use of the chemicals has made them the most commonly toxic and harmful contaminants in groundwater, which seriously affects human health and the safety of the ecological environment. In order to better understand the pollution characteristics of chlorinated hydrocarbons and the development status of remediation technologies, the migration and transformation characteristics of chlorinated hydrocarbons in groundwater were initially reviewed, and the occurrence state of chlorinated hydrocarbons in multiphase and multi-medium as well as the factors affecting their migration and transformation were analyzed and summarized. Then, the applicable remediation technologies of chlorinated hydrocarbons under different occurrence states were described respectively, including the research progress of experimental research and actual site remediation, as well as some existing issues in the remediation process. Finally, the future development direction of chlorinated hydrocarbon remediation technology was pointed out on the basis of current research status. The survey results indicate that the development of new wall media in PRB technology, environment-friendly sustained-release oxidation materials, the cultivation of engineering bacteria with high resistance and strong survivability and the combination of remediation technologies will be the development direction of chlorinated hydrocarbon contamination remediation in groundwater. Additionally, it is necessary to follow the principle of adapting the technologies to the hydrogeological conditions of the site in the selection and combination of remediation technologies.
