With the prolonged exposure time of NAPLs in soil and groundwater, volatile components in NAPLs, such as chlorine-containing solvents and light petroleum hydrocarbons, will gradually volatilize to form soil vapor which invades the ground and causes great harm to the environment and human health; meanwhile, easily soluble substances in NAPLs can be gradually dissolved into underground water to form a pollution plume so as to pollute the underground water in a large area.
