Journal of Hazardous Materials 501:140841(2026)
A project proposed and validated an innovative implementation of an in situ monitoring technique for LNAPL remediation treatments, based on ultraviolet light-induced fluorescence imaging (UVIF) combined with automated image post-treatment, to enable in situ and real-time monitoring of decontamination processes. A mini-camera integrated into a set of transparent wells embedded in the subsurface of LNAPL-contaminated zones was used to monitor a surfactant injection remediation process and a skimming operation involving groundwater drawdown. The technique was first calibrated and validated through lab and pilot-scale experiments, then used at a diesel-contaminated site. The pilot test revealed differences of <5% between recovery factors obtained via gas chromatography of soil samples and those measured with the proposed imaging technique. Site-specific calibration correlated fluorescence intensity from endoscopic images in transparent tubes with GC-analyzed LNAPL content, showing a strong correlation and relative errors below 10%. This enabled accurate in situ estimation of LNAPL variations: content remained mostly unchanged without treatment, decreased moderately during pumping and skimming, and dropped substantially during surfactant injection. The capability supports immediate treatment adjustments, thereby optimizing contaminant recovery rates. Results demonstrate that UVIF can effectively guide remediation operations by providing rapid feedback on contaminant removal dynamics. This near real-time capability enables optimization of treatment parameters, such as surfactant dosage, injection timing, or pumping duration, thereby improving hydrocarbon recovery efficiency. UVIF offers an alternative to conventional drilling-based methods, while improving measurement reproducibility and eliminating the need for destructive sampling. https://www.sciencedirect.com/science/article/pii/S0304389425037628/pdff

Increases in PFSA porewater concentrations over 35 months following in situ flushing were monitored at an AFFF site using porous cup suction lysimeters within a highly instrumented test cell. Results provided evidence that PFOS slow desorption kinetics contributed to slow contaminant rebound in measured porewater concentrations. PFSAs in the shallow (0.23 m depth) highly PFSA-impacted soil migrated downward during the monitored post-flushing period, with short-chained PFSAs migrating more rapidly in porewater than long-chained PFSAs. Following flushing, apparent equilibrium porewater concentrations at a depth of 0.61 m bgs were attained within two months for PFPeS, between 2 and 20 months for PFHxS, and 25 months for PFOS. For PFPeS and PFHxS, apparent steady state rebound concentrations (to 38% of their pre-flushing baseline levels, with no increasing or decreasing trend over time subsequently observed) were reasonably predicted based on an equilibrium model. PFOS rebound and ultimately vertical migration were highly impacted by non-equilibrium soil desorption. Excavation of elevated PFSAs in surface soil had no impact on PFSA porewater concentrations 0.38 m below the excavation over a 1.2-year post-excavation monitoring period. Long-term rebound data highlight the potential importance of mass transfer-controlled processes for PFOS leaching, and suggest that removal of elevated PFSAs in surface soil may take years until PFSA discharges to groundwater are diminished. https://www.sciencedirect.com/science/article/pii/S0169772226000094/pdff
This presentation describes a flux-based strategy to assess and remediate PFAS-impacted groundwater, emphasizing how mass flux measurements and targeted in situ treatment can improve remedial effectiveness. The case studies demonstrate the approach at bench and field scales. In a controlled column study, groundwater amended with increasing doses of colloidal activated carbon (CAC) showed progressively greater PFAS removal, confirming CAC's strong sorptive capacity and illustrating how dosage can be optimized to meet site-specific treatment goals. Building on these results, a case study applied flux-based characterization to design and install a permeable reactive barrier at a PFAS-impacted site associated with historical firefighting foam use. Passive flux measurements were used to identify dominant contaminant pathways and inform barrier placement and amendment dosing. Following CAC injection across the barrier, monitoring data indicated substantial reductions in PFAS mass flux and downgradient concentrations, validating both the material selection and the flux-guided design. Collectively, the case studies show that integrating mass-flux characterization with CAC-based in situ remediation provides a practical, scalable framework for controlling PFAS plumes and improving long-term remedial performance. https://nwremediation.com/wp-content/uploads/A3_Munsey.pdf

In situ biogeochemical transformation (ISBGT), consisting of a reaction pit filled with remedial amendments coupled with recirculation pipelines to increase hydraulic retention time and sustain favorable geochemical conditions, was implemented at a chlorinated ethene- contaminated site. Over 180 days, PCE and TCE declined by 98% with limited cis-DCE and VC accumulation, suggesting near-complete dechlorination. ISBGT operation led to a substantial drop in redox potential (-50 to -420 mV), creating reducing conditions favorable for iron and sulfur cycling. Metagenomic analysis revealed a temporal shift in functional potential, beginning with carbohydrate hydrolysis, followed by enhanced protein fermentation and acetate/H2 generation. Genes associated with redox iron and sulfur cycling, including mtrCDE and pilABC, increased notably. These processes facilitated the formation of biogenic iron sulfide (Fe-S) minerals, which likely played a central role in the abiotic reduction of PCE and TCE. ISBGT created a geochemically favorable environment where microbial metabolism continuously regenerated reactive Fe-S minerals, enabling sustained and synergistic CVOC degradation under highly reducing conditions. https://www.sciencedirect.com/science/article/pii/S2214714425023013/pdff
The FRED-PFAS onsite screening tool system utilizes a custom polymeric binding system that detects PFAS fluorocarbon chains by producing a high level of fluorescence that decreases in a dose-dependent manner when exposed to PFAS compounds. When combined with a modified SPE process, the system can reach ppt-level detection limits. It was demonstrated on multiple sample matrices, including AFFF rinsates, industrial wastewater, and groundwater. The sensor detects a wide range of PFAS compounds, performing best on analytes with 4 to 12 carbons. Strong signals are seen with EPA-6 analytes such as PFOA and PFOS. The sensor was tested on a wide variety of potential interferences, showing strong selectivity, and found some issues with high ppm metals and detergent concentrations. The presentation highlights the technical system validation, including an in-field pilot conducted at an AFFF facility where the system was compared to third-party analytical lab data. Strong correlation of system results to analytical methods was seen across samples. Performance data includes correlation data against methods such as EPA 1633 and TOF (R2 > 0.9). Case study results are presented that demonstrate the benefits of implementing onsite PFAS monitoring in an investigation/remedial application, with a focus on increased operational efficiency and projected long-term value for implementing such a monitoring system.

Groundwater Monitoring & Remediation 45(4):51-73(2025)
A methodology is presented to evaluate natural and enhanced degradation behavior at complex DNAPL sites using automated processing of CSIA groundwater datasets developed over several years of sampling. The method utilized CSIA datasets from the Orica Botany Bay Facility in Matraville and a former chemical manufacturing facility in Victoria to gain qualitative and semi-quantitative insights into natural and enhanced attenuation processes. An automated workflow was developed to evaluate CSIA data trends to assess degradation mechanisms and rates, providing insight into contaminant attenuation progress across large, complex sites. Isotopic enrichment factors were estimated based on temporal groundwater concentration and CSIA data at individual well locations. The enrichment factors were evaluated alongside corresponding geological, microbial, and geochemical data to identify areas where attenuation plays a significant role in contaminant mass reduction. Interpreting the CSIA data was verified by comparing to enrichment factors in literature, assessing other evidence supporting degradation activity, and considering aspects of the site conceptual model that could affect isotopic behavior. By applying an automated workflow to CSIA datasets, findings demonstrate a valuable standardized approach to gain useful knowledge on the contribution of monitored natural attenuation and enhanced biodegradation to contaminant mass reduction at complex sites. The study also illustrates some complexities associated with DNAPL sites that should be considered when interpreting CSIA data.
A rapid assessment pilot study evaluated the efficacy of low-cost, biologically based remediation strategies for organochlorine pesticide (OCP)-contaminated soil at a former agrochemical facility in regional New South Wales. Five treatment configurations were tested over 12 weeks, varying in compost amendment and aeration regimes, including cyclic aeration with and without compost, aerobic composting, passive aerobic treatment, and an abiotic control. Non-composted treatments with cyclic or passive aeration achieved the most substantial reductions in DDT concentrations, with decreases of up to 67%. Compost-amended treatments exhibited enhanced microbial activity but did not result in greater contaminant degradation. The study also documented co-occurring endosulfan, which showed partial reduction in several treatments despite low initial concentrations, highlighting the potential of simple, scalable bioremediation systems to address mixed OCP contamination. Limitations such as small-scale pile sizes, composite sampling, and short treatment duration may have influenced the outcomes. Future research should focus on longer-term trials, stratified sampling, and detailed microbial and metabolite analyses to optimize strategies for dual-contaminant remediation.

The potential to decrease the emissions of lower-chlorinated (LC)-PCBs (<3 chlorines) was assessed through bioaugmentation with aerobic PCB-degrading Paraburkholderia xenovorans strain LB400 in lab microcosms using historically PCB-contaminated sediments from a wastewater lagoon (Altavista, VA [AVL]) and an estuary (New Bedford Harbor, MA [NBH]). The impact of non-shaken vs shaken conditions was compared to airborne PCBs in LB400-bioaugmented AVL sediment (51% LC-PCBs) to better replicate field conditions. After 35 days, airborne LC-PCBs decreased by 54% in non-shaken bioaugmented AVL sediments, compared to a 60% decrease in shaken bioaugmented sediments. Bioaugmenting LB400 into unshaken NBH sediments (44% LC-PCBs) significantly decreased airborne LC-PCBs by 50% over 35 days. Biphenyl dioxygenase gene abundance decreased by several orders of magnitude after 16 days in all experiments, demonstrating a potential decrease in treatment effectiveness over time. Findings demonstrate that LB400 effectively degrades LC-PCBs with varying profiles over a range of environmentally relevant mixing scenarios. Further treatment delivery development has the potential to protect nearby communities from PCB exposure, decrease health risks, and improve quality of life.
A river catchment-scale approach was used to identify PFAS source zones and assess the relative importance of industrial PFAS sources in the River Mersey, UK, a post-industrial, densely populated catchment with diverse PFAS sources. Synoptic sampling and PFAS river load analysis identified key sub-catchments and river stretches contributing the majority of PFAS. The highest PFAS concentrations did not always correspond to the greatest loads. Most PFOS (64%), PFOA (49%), 6:2FTS (46%), and PFHxS (56%) were exported from the Upper Mersey sub-catchment, despite higher concentrations in northern sub-catchments, emphasizing the importance of load-based monitoring. Mass balance analysis of loads highlighted substantial inputs from specific river stretches, notably the Lower Irwell, River Tame, and Upper Mersey. While PFAS loads generally scaled with catchment area, yield (load/unit area) analysis identified disproportionately high exports from small headwater catchments, notably the upper River Roch (PFOA, PFHpA, and PFHxA) and Glaze Brook (PFBS). Industrial sources in the sub-catchments were confirmed using gadolinium anomaly analysis and consented discharge records. Gadolinium data suggested industrial discharges may contribute to PFAS occurrence at 62% of sample sites throughout the catchment. Findings demonstrate that spatial analysis of PFAS loads, rather than concentrations alone, is critical for identifying PFAS source areas.

A study evaluated the use of 14C assay to measure the rate constants for the degradation of chlorinated ethenes in contaminated aquifers using soil and groundwater samples from three sites. Use of 14C-labeled compounds makes it possible to quantify degradation by measuring the accumulation of degradation products that are otherwise difficult to discern from background levels (14CO2 and 14C-labeled soluble compounds). The soil and groundwater samples were added to serum bottles; one set of the microcosms was incubated in the absence of oxygen, and another set in the presence of oxygen. After injecting purified 14C -PCE, 14C -TCE, or 14C-cDCE, unlabeled compounds were added to bring the initial concentrations to ~200-1,700 µg/L. The microcosms were placed on a tumbling device to ensure gentle agitation during incubation. At weekly intervals over 42 days, 5 mL liquid samples were withdrawn, filtered, and sparged to remove the unreacted 14C-labeled parent compound. The amounts of 14C products that accumulated were used to calculate pseudo-first-order rate constants that ranged from 0.0092 to 0.24/year. https://ngwa.onlinelibrary.wiley.com/doi/epdf/10.1111/gwmr.70021

A study demonstrated that PFOA destruction in a pilot-scale incinerator led to a mixture of smaller PFCAs. Chemical ionization mass spectrometry was used to measure the concentration of PFCAs ranging from C2 to C9. The actual yield of PFCAs depends upon the location of PFOA injection and thus upon the peak temperature experienced within the furnace. A chemical kinetic mechanism was developed to explain the results. Two different pathways were considered: a low-temperature pathway that proceeds through a short-lived α-lactone intermediate and a high-temperature pathway that proceeds through cleaving a C-C bond in the alkyl backbone. Theoretical modeling of PFOA incineration at peak temperatures of ∼1130 and ∼1020 K predicted the formation of trifluoroacetic acid and other small PFCAs.

A surfactant-assisted ultrafiltration (UF) strategy is presented for enhanced PFAS separation through leveraging in situ assembly of PFAS molecules with the cationic surfactant cetyltrimethylammonium bromide (CTAB). Adding CTAB (0.14 mM) induces the formation of nanoscale complexes or micelles with PFAS, promoting effective retention by UF membranes (99.1% for 0.14 mM CTAB vs 30.3% without CTAB). Experimental and modeling results reveal a concentration polarization effect that leads to the accumulation of CTAB on the membrane surface. Even when the bulk concentration of CTAB is below its critical micelle concentration, localized micelle formation occurs near the membrane interface, enabling effective retention of PFAS. Notably, the CTAB-enhanced UF process is also effective in retaining other PFAS species, especially long-chain compounds such as PFHxA. Further experiments indicate that compared with electrostatic interactions, hydrophobic interactions between PFOA and CTAB play a more dominant role in forming micelles, thereby governing the subsequent retention by UF membranes. The study offers mechanistic insights into surfactant-mediated PFAS removal and presents a scalable, low-pressure membrane strategy for the effective treatment of PFAS-contaminated water.

Concave cubic gold nanoparticles were used for surface-enhanced Raman spectroscopy (SERS) to detect PFAS in ppm concentrations, differentiating the six PFAS (PFHpA, PFNA, PFDA, PFOA, PFHxS, and PFOS) regulated by the Massachusetts Department of Environmental Protection. Calculated Raman spectra, solid-state Raman spectra, and 19F NMR are used to further understand the physicochemical properties of these six PFAS. Quantitative analysis of PFOA and PFOS can be achieved from 0.1 to 10 ppm, while PFAS can be differentiated from three common fluorinated pharmaceuticals, and PFCA can be differentiated from C7 to C10 based on the length of the perfluoroalkyl backbone. The study highlights that SERS can be used to identify PFAS in real-world AFFFs, as confirmed separately by mass spectrometry.
A microcosm study assessed the effectiveness of bioaugmentation with an enriched dechlorinating consortium to remediate tetrachloroethane (TeCA), TCE, and sulphate ion in groundwater. Various conditions, including biostimulation and bioaugmentation approaches, were tested to evaluate the feasibility of biological treatment. Operating conditions facilitated the dechlorination of TCE into ETH, leading to an increase in the Dehalococcoides mccartyi population to 67% of the total bacteria, with reductive dechlorination (RD) rates up to 7 µeq/Ld. The RD performance of microcosms with real contaminated groundwater was negatively affected by the combined presence of TeCA and sulphate, indicated by a low abundance of D. mccartyi (<3%) and low RD rates (up to 0.39 µeq/Ld), suggesting that the native microbial population lacked the capacity for effective dechlorination. The principal component analysis plot highlighted distinct groupings based on microbial community across different microcosm conditions; microbial community structures dominated by D. mccartyi were associated with higher reductive dechlorination rates, while non-augmented and non-stimulated microcosms reflected distinct microbial communities dominated by non-dechlorinating taxa. In addition, RD decreased (48, 23, 22, and 14 µeq/Ld) with increasing sulphate concentrations (0, 150, 225, and 450 mgSO4 -2/L), further demonstrating the inhibitory effect of sulphate in the treated contaminated groundwater.

This review systematically summarizes how covalent organic frameworks (COF) structural modifications, specifically functional group engineering and pore optimization, regulate PFAS adsorption mechanisms via electrostatic, hydrophobic, and fluorine-fluorine interactions. To address challenges, including high synthesis costs of COFs and insufficient adsorption efficiency toward short-chain PFAS, the review also outlines future research priorities. Thus, this work not only provides theoretical guidance for designing high-performance COF-based adsorbents but also supplies ideas and methods for the control of PFAS.
This review focuses on the biodegradation of various PAHs, such as naphthalene, phenanthrene, anthracene, and pyrene, by bacteria, including Pseudomonas, Mycobacterium, Rhodococcus, and marine species from the Novosphingobium genus. These microbes use dioxygenase enzymes to initiate the breakdown of PAHs into less toxic intermediates. The review also explores the role of biosurfactants and biofilms in enhancing the bioavailability of PAHs, promoting more efficient degradation. It also discusses the advantages of microbial consortia, where multiple species collaborate to degrade a broader range of PAHs. Recent advancements in genetic engineering, synthetic biology, and nanotechnology are highlighted as promising tools to further enhance microbial degradation efficiency. The microbial bioremediation represents a sustainable solution to PAHs contamination, complementing traditional methods and offering significant potential for environmental restoration and human health improvement.

Under EPA's CERCLA program, soil suspected of lead (Pb) contamination is evaluated to assess the impact of soil Pb exposure on blood Pb levels. The decision to remediate partly relies on whether the measured soil exposure point concentration (EPC) exceeds an action level. EPA established data quality objectives (DQOs) to support data collection used to estimate the EPC and assess confidence in remediation decisions. To support DQO processes at sites where site-specific soil Pb relative bioavailability (RBA) is assessed, a statistical simulation model was developed that estimates false compliance/exceedance decision error probabilities based upon uncertainty in the RBA-adjusted EPC, employing model inputs defining the sampling protocol being evaluated, variability in total and bioavailable soil Pb across the assessed area, and analytical measurement uncertainty. A framework for utilizing the simulation model is presented using a hypothetical site informed by concentration and soil Pb bioavailability distributions from an actual Pb-contaminated site. Pre-sampling, false compliance/exceedance decision error probabilities were predicted for various sampling protocols. A DQO-compliant sampling protocol was then selected, and accuracy and precision in the measured EPC were assessed relative to a specified risk-based action level.
This review surveyed PFAS sensor technologies developed in the past decade, including optical, electrochemical, and emerging biosensing and whole-cell reporter platforms. For each sensor class, typical limits of detection, dynamic ranges, regeneration, and compatibility with repeated measurements in real and complex water matrices are summarized. The underlying recognition and transduction principles, including molecularly imprinted polymers, host-guest interactions, ion-selective membranes, nanomaterial-enhanced interfaces, and biological recognition elements, are highlighted to connect materials design with analytical performance. Across the platforms, key advantages include miniaturization, rapid response, and potential integration into portable or online monitoring systems. Major limitations involve selectivity among structurally similar PFAS, matrix interferences, long-term stability, and limited multi-analyte capability. The review discusses how current research addresses these challenges through preconcentration strategies, sensor arrays, nanostructured materials, and integrated sample handling and outlines future directions toward regulatory-grade, field-deployable PFAS sensors capable of continuous monitoring, multiplex detection, and scalable deployment in drinking water and environmental surveillance. https://pubs.rsc.org/en/content/articlepdf/2026/sd/d5sd00166h
