Abstract: Groundwater pollution mainly refers to the phenomenon of degradation of groundwater quality due to changes in its chemical composition, physical properties and biological characteristics caused by human activities. At present, China’s groundwater suffers from different degrees of pollution, the contaminated area is large and the pollution sources are complex, making it difficult to carry out groundwater pollution remediation work. This paper reviews the types of groundwater pollution and common groundwater pollution remediation technologies at home and abroad, and provides an outlook on the problems existing in the process of groundwater pollution remediation and the future development direction of groundwater pollution prevention and control.
