Groundwater pollution mainly refers to the chemical composition, physical properties of groundwater caused by human activities. The phenomenon of quality degradation due to changes in properties and biological characteristics. The stratum below the surface is complex and the groundwater flow is extremely slow. Therefore, groundwater pollution has the characteristics of slow process, difficult to find and difficult to control. Once groundwater is polluted, even if the pollution source is completely eliminated It will take more than ten years or even decades to restore the water quality; the existing groundwater pollution remediation mostly uses chemical remediation agents for water treatment.
