Effect of physical, chemical, and biological aging on activated carbon and biochar properties and PFAS immobilisation in soils
Shervin Kabiri, Karl C. Bowles, Shrinath Bhat, Divina Angela Navarro
Journal of Hazardous Materials, 2026
An increasingly common technique for managing per- and polyfluoroalkyl substances (PFAS)-contaminated vadose soils is immobilisation using sorbents. However, uncertainty remains regarding the long-term stability of PFAS immobilisation. This study investigated the effects of different environmental aging processes, physical (wetting-drying cycles), chemical, and biological, on the performance of widely used sorbents for PFAS immobilisation in soil using accelerated aging to simulate long-term environmental conditions. Six sorbents were evaluated, including two granular activated carbons (GAC), two powdered activated carbons (PAC), colloidal activated carbon (CAC), and biochar. Simulated physical and biological aging caused the greatest reductions in sorption efficiency, likely due to pore blockage, as confirmed by material characterisation, including surface area measurement and scanning electron microscopic images. Sorbent type significantly influenced performance, with PAC being the least affected by aging and biochar the most susceptible. When soils and sorbents were aged together, sorbent responses differed between soil types, with sorption efficiency decreasing after chemical aging in sandy soil and after physical aging in high-clay soil compared with other aging treatments. Despite these deliberately harsh simulated conditions, activated carbon-based sorbents remained highly effective, maintaining over 85% PFAS immobilisation in most scenarios, including highly contaminated soils (∑PFAS > 20 mg/kg). Overall, these findings demonstrate that although aging alters sorbent properties, activated carbon-based sorbents remain durable and effective for sustainable PFAS management under diverse environmental conditions.
Long-term laboratory-based evaluation of PFAS mobility after granular activated carbon (GAC) treatment: Influence of vegetation and soil properties
Shervin Kabiri, Karl C. Bowles, Divina Angela Navarro
Journal of Hazardous Materials, 2026
Per- and polyfluoroalkyl substances (PFAS) associated with contamination from aqueous film forming foams are persistent, mobile contaminants that pose risks to groundwater and ecosystems. This study evaluated the effectiveness of granular activated carbon (GAC) application (1% w/w), with and without vegetation cover (perennial ryegrass), in reducing PFAS mobility under controlled laboratory-based rainfall simulation conditions using trays with (L50 ×W20 ×H5cm) dimensions. Two soils with contrasting textures but similar PFAS contamination levels were used in the experiment. Leaching behaviour was evaluated over one year with simulated rainfall events using the laboratory rainfall simulator, capturing both infiltration and surface runoff, as well as particulates in the runoff. PFAS mobility was influenced by soil texture, groundcover and wetting and drying cycles. Soil A (sandy clay loam) generated more runoff, while Soil B (sandy loam) allowed greater initial infiltration. Perfluorooctane sulfonic acid (PFOS) concentration was increased in the runoff of untreated soil after a prolonged drying cycle due to the upward flux of PFOS during the drying period. GAC reduced PFAS concentrations by up to 97% in runoff and 99% in infiltration across both soil types, even over a year with multiple wetting and drying cycles. Groundcover initially increased PFAS concentrations in runoff, likely due to upward transport and evapotranspiration, but this effect diminished as vegetation was established. Combined GAC and vegetation treatments achieved > 99% PFAS reduction in most cases, with plant effects more evident after 60 days. These findings support in-situ GAC application, with or without vegetation, as a viable approach for managing PFAS-contaminated soils. Plants may cause a temporary increase in PFAS mobility during the initial period following plant application, with or without GAC, and management practices should account for this risk.

ACS Es and T Water, 2026
High Resolution Image Download MS PowerPoint Slide Constructed floating wetlands (CFWs) provide a passive pathway for the retention and accumulation of nutrients and perfluoroalkyl and polyfluoroalkyl substances (PFAS) present in treated wastewater (TWW). This two-year field-scale study investigated the accumulation of PFAS and nutrients in three native wetland species in a lagoon setting. During the plant establishment period and despite measurable nutrient and PFAS uptake in plant tissues, their removal from the water was limited due to short residence times (∼10–12 h). The highest nutrient accumulation in shoots was observed in Phragmites australis (0.14 g N/m 2 /day and 0.02 g P/m 2 /day), which showed the highest biomass (12.1 g/m 2 /day). Phragmites australis also exhibited the highest PFAS and precursor accumulation in tissues. PFAS removal improved after plant establishment, and the daily removal rate for PFAS (based on PFAS accumulation in plant tissue and sediment) was 240 ng/m 2 /d. Overall, CFWs show promise as a passive, modular solution for PFAS reduction in TWW, particularly after root system development and biofilm formation. However, long-term monitoring across multiple growth and harvest cycles and assessing the contribution of other mechanisms (such as sorption to growth media and accumulation in biofilms) are required to evaluate the CFW system sustainability under varying environmental conditions.
Migration of Per- and Polyfluoroalkyl Substances in Soil Under Rainfall Simulation
Minshu Liang, Shervin Kabiri, Michael J. McLaughlin, Divina Navarro
Clean Soil Air Water, 2026
Understanding the migration of per‐ and polyfluoroalkyl substances (PFAS) in soil via groundwater and surface water is vital for managing PFAS. PFAS transport via surface runoff during rainfall is less known than leaching. This study investigated PFAS migration under simulated rainfall in soils with varying contamination levels, examining multiple pathways to assess the factors affecting PFAS migration. Rainfall simulations were conducted over 15 days with wetting and drying cycles. Results indicate that leaching is likely the dominant pathway for PFAS transport, accounting for the largest proportion (on average 72%) of PFAS mass in the released fractions. Runoff was also an important pathway for long‐chain PFAS, whereas short‐chain PFAS were not detected in runoff. Both PFAS concentration and the wetting‐drying cycles influenced PFAS distribution. Leaching was negligible when PFAS concentrations exceeded 30 mg/kg perfluorooctane sulfonic acid (PFOS), potentially due to reduction in soil hydraulic conductivity. PFAS concentrations in runoff increased following extended drying periods, suggesting accumulation of PFAS in the upper soil. This pattern of evapoconcentration, likely driven by capillary water movement and subsequent evaporation, is consistent with the resurgence of concentration in surface soils. Overall results highlight that surface runoff is an important pathway for PFAS transport, particularly for long chain PFAS. Wetting and drying cycles may promote accumulation in the upper soil layers, increasing the potential for mobilization via runoff. By considering both leaching and runoff, this study contributes to a better understanding of PFAS transport in soils and can help inform management strategies to reduce contaminant spread to surface waters.
Field assessment of a constructed wetland for stormwater treatment: A focus on PFAS management

Journal of Hazardous Materials Advances, 2026
Current options for treating per- and polyfluoroalkyl substances (PFAS) in stormwater generally rely on expensive, construction-intensive ex-situ technologies or adsorption barriers. However, for some sites it would be preferable to have a lower-cost, passive option. This field study investigated the variability in PFAS concentration in urban stormwater over 14 months and assessed the performance of an established surface flow constructed wetland (SF-CW). Highest PFAS concentrations in stormwater were for long chain (LC-) PFSAs (C6+: 101-783 ng/L) followed by short chain (SC-) PFCAs (C4-5: 15-91 ng/L), LC-PFCAs (C8+: 7-20 ng/L) and SC-PFSAs (C4-7: 3-22 ng/L). PFAS varied between consecutive storm events, with values during high-flow events increasing by 2- to 5-fold. ∑ 27 PFAS measured in samples collected at the SF-CW outlet were lower (but not significantly, p > 0.2) than those measured before the detention basin. Consequently, the SF-CW appeared to reduce SC-PFCAs and LC-PFSAs loads by 31.5% and 19.4%, respectively. However, no removal of PFAS precursor was observed, indicating that the SF-CW was not effective for precursor attenuation. PFAS detected in sediments, soils and plants suggest that 1) sediment-bound PFAS were removed via settling in the detention basin (SC-PFCAs: <0.0002 to 0.0005 mg/kg; LC-PFSAs: 0.0011 to 0.0227 mg/kg; equivalent to <1% of the PFAS load) 2) soil adsorption (SC-PFCAs: <0.0002 mg/kg; LC-PFSAs: 0.0011 to 0.0227 mg/kg), particularly for long-chain PFAS (90 g/y of LC-PFSAs retained in the soil, equivalent to 12% of PFAS load), was a key removal mechanism within the SF-CW, and 3) dissolved PFAS in stormwater can also be removed via plant uptake (SC-PFCAs: <0.0002 to 0.0168 mg/kg; LC-PFSAs: <0.0002 to 0.170 mg/kg; equivalent to ∼1% of PFAS load). Findings highlight SF-CW can reduce PFAS in stormwater however removal needs to be optimized for operational performance, and safeguard against potential environmental impact.

Journal of Contaminant Hydrology, 2026
Per - and polyfluoroalkyl substances (PFAS) contamination is widespread in our environment and partitioning at interfaces is a major factor that influences their fate and transport within a soil pore space. To develop better PFAS management and remediation strategies, we need to gain a deeper understanding of PFAS soil-porewater partitioning processes in situ. In this study, we investigated the partitioning of PFAS in a spiked agricultural soil and an Aqueous Film-Forming Foam (AFFF) impacted “aged” soil under various soil moisture conditions and when the soil pores were filled with a non-aqueous phase liquid (NAPL). Sulfur (S) K-edge X-ray absorption near edge structure (XANES) spectroscopy was used to probe S speciation in situ, and spectra were analysed applying a Gaussian Curve Fitting (GCF) approach. Six major S species were identified in both soils and PFAS partitioning behaviour was interpreted based on changes in sulfonate fractions, representing sulfonic acid-based PFAS. In the spiked soil, sulfonate fractions increased the most when soil pores had a water saturation ratio (S W ) of 0.25, whereas in the “aged” soil the most significant increase occurred for completely saturated soil pores. These differences were attributed to differing micellar formation behaviours in freshly spiked versus AFFF impacted “aged” soils. A linear correlation was also observed between the ratio of total reduced S and sulfonate fractions against the degree of saturation of “aged” soil. Furthermore, in spiked soil it was observed that a lower percentage NAPL content at S W = 0.25 led to higher partitioning of sulfonic acid-based PFAS.

Resources Conservation and Recycling, 2026
• Chemicals in wastes can be a barrier for circular economy. • Assessing availability and effect of chemicals in reuse scenarios is key to safe reuse decisions. • Four key research themes are outlined to guide Australia’s management of waste chemicals. • An iterative approach to assess availability and effect of waste chemicals is proposed. Achieving a circular economy is dependent on our ability to safely reuse materials that would otherwise be classed as waste. This paper outlines challenges facing Australia in the context of international research trends for waste and waste reuse in a circular economy. Our understanding of the potential chemical hazards contained in our wastes and products with recycled content is a challenge due to the variability of waste and product materials. Such variability amplifies the need to ensure representative sampling to expand analytical and experimental methods and establish fundamental data and information related to chemical availability and ecological and human health effect. Four key themes are identified that need consideration, from identification of chemicals in our ever-diverse waste streams to dissemination of outcomes as guidance and for uptake in policy. Gaps in knowledge and the research required to address the four themes are outlined. The long-term development of an acceptable and consistent set of guiding principles related to the sampling, characterisation, categorisation and safe reuse of waste is shown to be important, further enabling resource recovery and reuse of materials.
Granular activated carbon reduces PFAS bioavailability and protects ant colony growth in soil
Divina Navarro, Ben Hoffmann, Wenchao Lu, Karl Bowles, Jason Kirby
Journal of Hazardous Materials Letters, 2025
Per- and polyfluoroalkyl substances (PFAS) are persistent contaminants that pose risks to ecological and human health. Soil stabilisation using sorbents such as granular activated carbon (GAC) can reduce PFAS mobility and bioavailability. Previous studies have focused on plants and earthworms, but bioavailability in species relevant to arid and semi-arid environments remains poorly understood. This study examined the effectiveness of GAC in reducing PFAS bioavailability to tropical fire ants ( Solenopsis geminata ). Two PFAS-contaminated soils were amended with 1 % or 5 % (w/w) GAC, incubated, then subjected to 5-day and 2-month ant exposure trials. Results showed that GAC reduced leachable ∑ 29 PFAS by 73–100 %, with greater reductions at later post-treatment leaching assessments and at 5 % GAC. PFAS exposure in untreated soils impaired ant colony growth, whereas GAC addition mitigated these effects and reduced PFAS concentrations in ants by < 97 %, with the greatest reductions observed in the sandy soil, consistent with leaching results. Non-target PFAS detected in ants collected from untreated soils were not detected in ants from GAC-treated soils, indicating GAC's broad sorption performance. Risk quotients calculated suggest that GAC can substantially lower potential risk to mammals and birds that feed on ants. Overall, findings underscore the value of soil stabilisation strategies, especially in ecosystems where invertebrates influence contaminant exposure. • PFAS leaching from soils was reduced by ≥ 83 % using granular activated carbon. • Fire ant bioassay showed colony growth was impaired by PFAS in untreated soils. • GAC can reduce PFAS bioaccumulation in ants by at least 95 % • Uptake of non-target PFAS in ants were also reduced by GAC, showing broad sorption effectiveness. • GAC can reduce PFAS ecological risk and limit potential trophic transfer to higher organisms.

Enhanced immobilisation of per- and polyfluoroalkyl substances (PFAS) using a combination of sorbents and plants: A controlled rainfall simulation study
Minshu Liang, Shervin Kabiri, Michael John McLaughlin, Divina Navarro
Science of the Total Environment, 2025
Activated carbon (AC) has been widely used to remediate soil contamination caused by per- and polyfluoroalkyl substances (PFAS). Groundcover by vegetation has also shown potential in limiting off-site movement of PFAS from contaminated sites. However, the effectiveness of AC and groundcover in mitigating PFAS migration from soil has not been adequately studied. A rainfall simulation was conducted to investigate the migration of PFAS from PFAS-spiked soil via leaching, runoff and suspended materials during storm events. The efficiency of two AC sorbents (1 % w/w) and groundcover (perennial ryegrass) individually or together were evaluated as PFAS remediation techniques. On average, AC reduced perfluorooctanesulfonate (PFOS) concentrations by 91 % in leachates and 85 % in runoff. Groundcover reduced PFOS concentrations by 44 % in leachates and 43 % in runoff. The combined use of both AC and groundcover reduced PFAS concentration by 94 % in leachates and 86 % in runoff. Though its efficacy was lower than AC, groundcover was able to mitigate the movement of short-chain PFAS, e.g. perfluorobutanesulfonate. A significant proportion of PFAS migration was mitigated via plant uptake when plants are present, reducing the amount of PFAS in leachates and runoff. This study suggests that a combination of AC and groundcover could be a more effective method of reducing PFAS migration during storm events.
