To investigate the characteristics of migration and distribution of phenanthrine plays an important role in the control of polynuclear aromatic hydrocarbons (PAHs) contamination. This experiment simulate the migration and distribution of phenanthrine in soil-groundwater by using indoor dynamic soil column test and hydrogeological theories so as to understand the condition and rules of phenanthrine contamination in underground environment. The study shows that the surface soil interception of phenanthrine is noticeable. 180 days later, 90% phenanthrine is not detected. And a small amount of phenanthrine in eluent is found. This shows that phenanthrine penetrates aeration zone rather easily. Attenuation of phenanthrine in aeration zone is generally composed of two phases, non-biological effect and biogeochemical effect. Continuous rainfall is more likely to penetrate aeration zone to pollute groundwater than pulse rainfall.
