With the rapid economic and social development, China's groundwater pollution becomes serious and urgently needs repairing. However, due to the diversity of pollution and complexity of hydrogeological conditions, many of the remediation techniques actually used are not the best option. At present, researchers have tried to establish and optimize the technical evaluation system of groundwater pollution remediation using a variety of evaluation methods, such as multi-criteria decision analysis method (MCDA), life cycle assessment method (LCA), cost-benefit analysis method (CBA), etc. Aiming at the problem that China still lacks perfect standards and legal norms to guide remediation decision-making this paper reviews the research progress of groundwater pollution remediation technology evaluation methods by means of literature research and compares and analyzes the advantages and disadvantages of different evaluation methods. The results show that MCDA has obvious advantages. In addition, when using AHP to construct the evaluation system, selection of evaluation indicators and determination of index weights have a significant impact on the evaluation results of groundwater remediation technology. In a word, in order to optimize the existing evaluation methods it is necessary to conduct more in-depth research on selection of evaluation indicators, determination of index weights, and organic combination of evaluation methods according to the actual situation in China.
