In recent years, with the development of soil pollution surveys of enterprise lands in key industries and the standardization of environmental survey systems for construction lands, the market demands for polluted site surveys have increased dramatically in China. Contaminated site sampling is an important link to ensure the reliability of site survey results, but the research and practice of survey techniques and equipment on contaminated sites are still in the initial stage. Therefore, in order to provide basic information on the research and development of in situ weak disturbance sampling techniques and equipment for polluted site surveys in China, in this paper, the current advanced soil and groundwater sampling techniques and equipment at home and abroad were systematically reviewed, including their development, scope of application, advantages and disadvantages, the reasons for the disturbance of the sampling equipment during the sampling process were analyzed, and the problems and development trends in the field sampling process were finally summarized.
