“…As one of the in chemical remediation techniques, electroremediation and electromigration were used to remove PFOA (Table 4), and it was found that the removal of PFOA reached 19% at 20 mA (Ganbat et al, 2022) (Hou et al, 2022). In recent years, the study of ozone in contaminant remediation has gradually received attention from researchers, and it has been found that ozone can diffuse well in unsaturated porous media and effectively remove PAHs from porous media (Russo et al, 2010).…”

Soil and groundwater contamination has always been a global concern. Contaminants are migrated and transformed in the soil and groundwater environments, which in turn pose potential environmental risks to humans. This paper describes four typical contaminants, including heavy metals, polycyclic aromatic hydrocarbons, microplastics, and perfluorinated and polyfluoroalkyl substances. Based on a systematic summary of the sources, hazards, and migration behaviors of these four contaminants, various existing remediation methods are analyzed, and the advantages and disadvantages of different methods are discussed. Finally, the future research prospects of soil and groundwater remediation are described, and the significance of the study of contaminant migration and remediation in the subsurface environment is emphasized. This research can help to provide theoretical and technical support for the study of contaminant migration and removal in soil and groundwater environments, and further improve the removal rate in actual contaminant sites.

“…Electroosmosis refers to water transport toward the cathode, which can also mobilize PFOA. Conversely, due to PFOA negative charge (mainly as an anion in the environment), electromigration will refer to the mobilization of PFOA toward the anode (Ganbat et al, 2022;Sörengård et al, 2019). Therefore, PFOA is in uenced by both of these ows with opposing transport vectors.…”

Perfluorooctanoic acid (PFOA), which is an emerging persistent organic and one of the most commonly used PFAS, has a wide range of applications in industrial and production processes, and humans can regularly be exposed to it, so remediation of PFOA-contaminated soil is of great importance. This research presents the importance of PFOA soil pollution, soil remediation related technologies, their mechanisms and the order of remediation priority for three different hypothetical scenarios. Our comprehensive literature review shows that while some remediation methods have shown positive results, some, such as ultrasound, are ineffective in terrestrial ecosystems. Despite the fact that generally, the selection of a practical and compelling soil remediation technique depends on site assessments, our investigation and analysis by implementing an analytical hierarchy process and considering remediation time, environmental impacts, ecological impact, soil disturbance, post management, etc. as criteria, leads to the solidification/stabilization, oxidation, electrokinetic, phytoremediation and bioremediation as the most feasible and promising approaches for remediation of PFOA contaminated sites in our three suggested scenarios, but with different preferences. On the other hand, negative aspects of the electron beam, pulsed corona, and ball milling have placed them at the bottom of our selection list for field scale remediation.
