Abstract Taking an industrial site in the intertidal zone of the river estuary as the research object, the total
petroleum hydrocarbons (TPHs) of soil and groundwater samples were collected and investigated, and the migration
law of TPHs in the soil and groundwater of the industrial site in the intertidal zone and the influence of tide on it
were analyzed and discussed. The results showed that the groundwater level in the area along the river of the site
fluctuated obviously by tide, the average permeability coefficient of the aquifer was 1.40 m/d, and the permeability
of aquifer near the river was better. The maximum exceeding multiple of TPHs in the soil of the site was 1.39 times.
The pollution was mainly distributed in the core production area, mainly neared the junction between the first two
different lithological layers. The vertical distribution of TPHs in soil was significantly influenced by stratum
structure and tidal effect. When the water level decreased, TPHs migrated downward and part of TPHs remained in
vadose zone, while when the water level rose, it led to the opposite process. The maximum exceeding multiple of
TPHs in the groundwater of the site was 95.23 times, the pollution plume center was consistent with the main areas
of soil TPHs pollution, and the groundwater flow field had a significant impact on the migration and distribution of
