Abstract：Due to their widespread use, unreasonable disposal, and their persistency in the subsurface environment, chlorinated ethenes have become one of the most commonly contaminants in groundwater and soils,. Since they are volatile, toxic, and carcinogenic, they have been widely concerned. Based on the literature review, the sources, hazards, and pollution of chlorinated ethenes are summarized. Furthermore, the remediation technologies of chlorinated ethenes, such as physical, biological, and chemical methods are concluded. Physical methods include aeration and activated carbon adsorption, chemical methods include chemical oxidation and chemical reduction, and biological methods include bioremediation and phytoremediation. Moreover, the development trends of TCE and PCE remediation technologies are looked ahead, and the microbial remediation, nano-metal particles, and photocatalytic oxidation technology are appreciated, and it is recommended that researches and applications of these three areas should be strengthened.
