High levels of perfluoroalkyl substances (PFASs) were observed in rural areas near a fluorochemical industrial park (FCIP) in the Yangtze River Delta region. The concentrations of total PFAS (∑PFASs) in soil, surface water, groundwater, and rainwater were in the range of 0.6–64.6 ng/g dry weight, 15.6–480.9, 4.8–614.6, and 13.4–542.2 ng/L, respectively. PFASs in rainwater and groundwater were higher than in surface water. The influence of the FCIP on rural soils extended to a distance of approximately 4 km based on the changes in PFAS compositions. The impact on surface water is mainly through direct river flow connected with contaminated sources, which may extend farther than 7 km in the case of unrestricted flow but much shorter distance for unconnected rivers. The penetration of PFASs in groundwater aquifers can extend as far as ca. 6 km, while direct water flow is the main transport route for PFASs. The influence radius of the FCIP can be as far as 60 km due to atmospheric precipitation.
