This paper is the result of the water resources and environmental geological survey engineering.
[Objective]The investigation and remediation of groundwater pollution in China has been paid more attention by the scientific community. Understanding and mastering the methods and technologies of groundwater pollution remediation is helpful for the scientific remediation of polluted sites.[Methods]Based on the systematic analysis of groundwater pollution remediation cases at home and abroad, this paper summarizes the technical methods implemented on the groundwater pollution remediation site in China.[Results]Combining the characteristics of China's regional economic development and the results of groundwater pollution investigation and evaluation, it is believed that the complex hydrogeological conditions are restricted, and the pollutants are affected by the heterogeneity of groundwater velocity, flow direction and permeability coefficient, which makes the restored site appear tailing. and rebound; pollutants are restricted by the lithology of aquifers, and the adhesion and desorption of pollutants and low-permeability rock and soil often generate secondary pollution; Groundwater quality assessment, groundwater pollution health risk assessment, and pollution degree assessment provide a scientific basis for the development and completion of restoration projects.[Conclusions] Groundwater pollution remediation in China faces opportunities and challenges in the coordination of methods and technical methods. Groundwater pollution remediation needs to rely on aquifer lithology and hydrogeological conditions.
Highlights: Aquifer lithology and groundwater dynamic conditions are the keys to groundwater pollution remediation; according to the complexity of pollutants and sites, groundwater pollution remediation is sorted by methods and technologies.
