Corrado, J.J. ǀ DCHWS East 2025 Spring Symposium, 2-4 April, Philadelphia, PA, 17 slides, 2025

A former manufacturing site in central New Jersey with contaminated soil and groundwater is divided into several Operable Units (OUs). One involves two surface impoundments, which were used to store waste from a coal light oil refining process. The 4-acre impoundments contained ~54,500 yd³ of acid tar containing VOCs, primarily benzene. To date, ~2,575 yd³ of acid tar have been removed, leaving ~51,925 yd³ remaining in the impoundments. The impoundments are lined underneath with a ~1-ft-thick clay layer and a 3-ft water cap to reduce VOC emissions into the atmosphere. Impacted groundwater underneath the impoundments is collected and treated. Following site flooding from Tropical Depression Ida, a ~25-ft tall mechanically stabilized earth wall was designed and installed to protect the impoundments from future flooding events while providing a working platform from which to perform planned remedial activities. Remedial action includes excavating and dewatering the impoundment acid tar material, providing emission and odor control measures, offsite shipping of the principal threat waste for treatment/destruction as an alternative fuel for cement kilns, treating the remaining acid tar and contaminated soil and/or clay in the impoundments with in situ soil stabilization, and backfilling the excavated areas and installing a protective cap over the entire footprint. The presentation covers the evaluation testing and design development associated with utilizing and implementing Aero Aggregate® Ultra-Lightweight Foamed Glass Aggregates (UL-FGA®) as a floating cover system to reduce potential VOC emissions from the water cap, the pilot work completed to determine the required floating cover thickness, and conclusions, recommendations, and findings related to utilization of the innovative material as a floating cover system and its anticipated emission reduction potential. https://mediacdn.guidebook.com/upload/213716/PRjFKwO8ACCNcdplL4BqRhB2i0tcQQGMyDC6.pdf

This case study documents a comprehensive remedial design (RD) approach for the American Creosote Works (ACW) Superfund site and highlights remedial action implementation strategies, including technical problem-solving and stakeholder engagement. The RD was segmented into three main parts due to the site's complexity, stemming from multiple contaminant media zones within diverse site-specific geology. The site required a combination of remediation technologies, including barrier wall containment, thermal treatment, soil excavation, consolidation, capping, and in situ enhanced bioremediation. Key project achievements included:

• Prioritizing source control and human health risk reduction through strategic design modifications for contaminant media zones.
• Optimizing construction sequencing to minimize soil handling and expedite off-facility remediation.
• Developing a performance-based thermal treatment design with robust monitoring requirements.
• Implementing a "trust but verify" approach to review previously developed designs while encouraging stakeholder engagement.

The project exemplifies a holistic approach to environmental remediation, demonstrating how technical excellence, stakeholder trust, and collaborative problem-solving can be integrated to address complex environmental restoration challenges. https://mediacdn.guidebook.com/upload/213716/YWRBsCpvDsDOPC1Q5Km3KG48Wu6Wv8EBxkQ2.pdf

Underlying soil and groundwater at the Jackson Ceramix Superfund site, a former china manufacturing facility, were contaminated with CVOCs. The 233-acre site is divided into three operable units (OUs). OU-1 and OU-2 encompass contaminated soil and sediment west and east of an active railroad, respectively. OU-3 encompasses contaminated groundwater within the overburden and bedrock aquifers and has yet to be addressed. A remedial investigation, feasibility studies, and pre-design investigations were completed, and the nature and extent of contamination have been delineated. COCs include metals in soil, sediment, and groundwater, and DNAPL CVOCs. The dissolved metals and CVOC plume are in direct communication with surface water and site wetlands. Technologies selected and combined into RA alternatives include in situ stabilization to reduce bioavailability of metals in contaminated soils and sediments; ex situ stabilization to dewater and reduce leaching of contaminants from excavated materials; excavation and dredging of metals-contaminated soil and sediment; wetland dewatering; offsite disposal of excavated and dredged hazardous and nonhazardous waste soil/sediment; and in situ thermal treatment to address soil and groundwater DNAPL and high CVOCs associated with several CVOC source areas. Each remedial area had unique conditions, constraints, and challenges that needed to be addressed in the design for the successful implementation of the RAs. Implementation and restoration challenges also resulted from the presence of forested areas, wetlands, and critical ecological habitats. Significant coordination with site stakeholders and multiple property owners was required for gaining site access, securing tree-removal rights, identifying unknown property title transfers, and addressing redevelopment concerns. Addressing these complex issues in the RDs resulted in a holistic remediation approach. https://mediacdn.guidebook.com/upload/213716/iEURPEawv8oc5NEsXXHLHYVkNtsQ2zJ5GyGp.pdf

A project was conducted to demonstrate and validate the use of PFASsive™, a dialysis-based passive sampler "peeper" for measuring PFAS in sediment porewater and surface water. A comprehensive field study was conducted at nine different locations in freshwater creeks receiving PFAS from an AFFF site in May 2024. The presentation highlights the benefits of passive sampling for PFAS, sample design, fieldwork, and discusses the results of C_free measured in the passive samplers compared to measured PFAS in bulk media and organism tissue. PFOS was generally the most frequently detected (and highest detected PFAS) in samples. PFAS passive sampling results were well correlated with uptake. For example, passive sampling PFOS C_free was positively correlated (r² values of 0.73 to 0.88) with concentrations in clams exposed to site surface water and oligochaete worms exposed to site sediment. The data indicated that passive sampling can be used to help understand the fate and availability of PFAS in aquatic systems. https://s3.amazonaws.com/amz.xcdsystem.com/A51108D5-FA2F-2B6D-01D92AC0F42DCE3B_abstract_File25469/PresentationPDF_252_0314032708.pdf

A lesser-known ISCR approach is Biogeochemical Reductive Dechlorination (BiRD), the core of which is engineered in the in situ creation of permeable reactive zones (PRZ) populated by metastable ferrous monosulfides. Following a summary of scientific and practical motivations for commercialization of BiRD, the presentation covers site background including 30 years of remedial efforts, pilot test goals, synthesis of remediation-focused conceptual site model (CSM) and pre-design investigation (PDI), pilot test design basis, BiRD selection, pilot test design-execution-results, and implications for completion of subsurface cleanup. The pilot test successfully achieved goals because of effective planning, specification, execution of the PDI, treatment technology selection, and pilot test design and execution. Emphasized are upfront CSM synthesis, application of high-resolution site characterization tools, hydraulic fracturing technique, site-specific solid- and aqueous-phase reagents, and over 4 years of groundwater sampling and analysis events covering baseline and performance assessment, including Compound Specific Isotope Analysis for TCE and cDCE. The BiRD PRZ successfully reduced TCE mass flux with point concentration values exceeding 50,000 ug/L, with no accumulation of vinyl chloride or methane. The CSIA data documented the dominance of abiotic transformations. https://s3.amazonaws.com/amz.xcdsystem.com/A51108D5-FA2F-2B6D-01D92AC0F42DCE3B_abstract_File25469/PresentationPDF_210_0321093010.pdf

In addition to a soil removal interim action, EPA initiated pilot studies to finalize the remedy for groundwater remediation at a former electroplating facility in Dallas, Texas. Chemistries and injection approaches were selected for pilot testing to treat both Cr(VI) and PFAS. A formulation combining colloidal carbon and base-activated sodium dithionite was selected for the study to reduce Cr(VI) and sequester PFAS. A pilot test was conducted to evaluate the efficacy of this combined remedy. The presentation covers the design considerations for the pilot test, injection approach, logs, and post-injection groundwater results for Cr(VI) and PFAS (primarily PFOS and PFHxS). Based on the pilot test results, it appears that colloidal carbon combined with base-activated sodium dithionite is a viable in situ treatment option for these dual contaminants. https://www.youtube.com/watch?v=XmceiqBD2uQ

Batch experiments were conducted to investigate the stabilization effect of heavy metals in soil from an iron-smelting site using multiple materials. Results showed that FeSO4 simultaneously reduced the bioavailable heavy metal (BHM) concentrations of Pb (61.1%), Zn (28.1%), and As (68.6%), respectively. FeSO₄ was further applied at a contaminated site. Results indicated that the heterogeneous distribution of stabilization efficiency deviated from that of batch experiments, which were influenced by multiple factors. Compared to the control group, the bioavailable Pb, Zn, and As concentrations decreased by 23.1, 13.6, and 4.73 mg/kg, respectively, when the injected FeSO4 concentration was 0.27 mol/L in the saturated zone. The decreased concentrations of bioavailable Pb, Zn, and As decreased with the distance from the injection well, showing a limited radius of influence at 1.0-2.0 m, larger than the theoretical value (0.92 m). Correlation analysis revealed a significant negative relationship between the change in BHM content and the fraction of BHM content before stabilization (FB), indicating that FB significantly controlled the stabilization efficiency. While excess injected FeSO₄ had only a slight influence on the stabilization efficiency of heavy metals, it negatively impacted groundwater. This study provides new perspectives for in situ stabilization and highlights the importance of pilot-scale experiments over batch experiments for guiding engineering activities.

The combination of multiple factors has led to regulatory concern and restrictive guidance to prevent false-positive PFAS sampling results. This project was completed to 1) assess several potential sources of bias and whether field sampling materials, equipment, and processes may pose a significant risk of sample contamination (or if current guidelines are unnecessarily restrictive, increasing time and cost in the field); 2) evaluate whether PFAS stratification in groundwater and surface water columns is significant enough to bias results, including the amount of the surface microlayer that is captured in the sample using different sampling methods; and 3) review existing studies on PFAS precursor transformation as a function of sample storage temperature and duration. https://sepub-prod-0001-124733793621-us-gov-west-1.s3.us-gov-west-1.amazonaws.com/s3fs-public/2025-04/ER19-1205%20Final%20Report.pdf?VersionId=wLg36On_WPuIUIvA_1TFpNDZtw.Ive1L

A study focused on optimizing laccase production from Enterobacter sp. GR18, which was isolated from the Grawan mineral spring near Sardasht, West Azerbaijan Province, Iran, and identified through comprehensive biochemical tests and 16S rRNA sequencing. Advanced methodologies were used to optimize laccase production conditions. The purified laccase enzyme was characterized using SDS-PAGE. The study investigated the effects of various carbon and nitrogen sources, metal ions, and inducers on enzymatic activity. Structural changes in crude oil samples treated with laccase were analyzed using NMR spectroscopy. Enterobacter sp. GR18 showed exceptional laccase activity among 33 isolated strains. Glucose and yeast extract were the most effective carbon and nitrogen sources, respectively. Copper and iron ions significantly enhanced enzyme activity. NMR spectroscopy indicated substantial breakdown of complex hydrocarbons in crude oil samples posttreatment, demonstrating the enzyme's effectiveness in hydrocarbon degradation. The study reveals the potential of Enterobacter sp. GR18 for high laccase production and efficient hydrocarbon degradation under extreme environmental conditions.

Research investigated the efficacy of magnesium oxide (MgO) activated ground granulated blast furnace slag (GGBS) in remediating MTBE-contaminated clay soil through lab tests. Contamination was simulated by artificially introducing 2.25 mg MTBE/kg of soil in the lab. The GGBS activation process involved mixing GGBS and MgO in a ratio of 3:1. The mixture was then added to both natural and contaminated soil samples at percentages of 0.25%, 0.5%, and 1.0%. Results demonstrated that adding the binder improved the strength of both natural and contaminated soil samples, with the magnitude of strength enhancement dependent on the percentage of the additive and the curing time. Scanning electron microscopy analysis indicated that the changes in soil properties and remedial effectiveness were attributed to chemical interaction between the soil minerals, the pollutant, and the binder. The results showed that the selected additive is suitable for the remediation of the contaminated soil.

Molecular dynamics simulations were carried out for PFAS at varying interfacial densities to understand the impact of organic loading on PFAS adsorption. Adsorbed PFAS form strong mutual interactions that give rise to ordered interfacial coatings. These interactions often involve near-cancellation of hydrophobic attraction and Coulomb repulsion. Findings explain an apparent paradox whereby PFAS adsorption isotherms often suggest minimal mutual interactions while simultaneously displaying a high sensitivity to the composition and density of interfacial coatings. Consideration of the compounds present with PFAS at the interface has the potential to allow for more accurate predictions of fate and transport and the design of more efficient remediation approaches.

A study developed a quantitative assessment framework based on the life cycle assessment integrated with best management practices (LCA-BMPs) to evaluate the environmental, economic, and social sustainability of in situ electrical resistance heating coupled with steam enhanced extraction (ERH-SEE). Results indicated that ERH-SEE offered better environmental sustainability performance compared to ERH only, with a carbon emission reduction of 52.6%. ERH-SEE also significantly reduced human toxicity, resource consumption, and ecosystem impacts under the same remediation scenarios. Taking the renewable energy share in energy structure in different countries into consideration showed that higher shares of renewable energy used in energy supplies can substantially reduce the environmental footprint of the studied scenarios. Economic sustainability assessments showed that ERH-SEE was more sustainable than ERH only, reducing direct economic costs by 35.7% and providing higher levels of worker employment. ERH-SEE involved more complex operational procedures and presented more health risk exposure scenarios compared to ERH only, resulting in slightly more pronounced worker safety issues. Final normalized results showed that the overall sustainability of ERH-SEE and ERH only were 78.4 and 61.5, respectively, demonstrating that the sustainability performance of ERH-SEE was better than ERH only. Applying ERH-SEE in groundwater remediation where significant heterogeneities occur in the subsurface can increase the sustainability in developing countries, due to the lower percentage of renewable electricity in the energy supply.

A three-dimensional numerical model was applied to investigate using thermal remediation of contaminated sites in fractured bedrock in global and local sensitivity analyses for the significance of six variables that potentially influence heating performance in fractured rock. These variables include the radius and energy delivery strength of the heat source, the fracture aperture, fracture spacing, groundwater flow velocity, and the thermal conductivity of the rock matrix. A discrete Latin Hypercube-One-at-A-Time scheme was proposed and utilized as an experimental design and data analysis method for the discrete variables that apply to this case. Results show that the radius of the source and energy delivery strength were the most sensitive parameters at all four monitoring points within the heating area. To minimize heat dissipation, additional heating wells were demonstrated to be effective for a small or pilot scale site (5 < r < 10 m), while the increase of energy delivery strength was more applicable for larger sites. Extra efforts should be invested to minimize heat dissipation when large fractures (2b> 1,600 μm) are identified in the heating area. Resamplings and re-evaluations with one-way perturbation in both positive and negative directions are suggested to avoid biased results caused by perturbations that occur in only positive or negative directions. https://ngwa.onlinelibrary.wiley.com/doi/epdf/10.1111/gwmr.12696

The first constant-electrode potential (CEP) quantum calculations are presented for PFAS degradation on electrified surfaces to shed light on their electrochemical processes. The advanced CEP calculations provide new mechanistic details about the intricate electronic processes that occur during PFAS degradation in the presence of an electrochemical bias, which cannot be gleaned from conventional density functional theory calculations. The CEP calculations were complemented with large-scale ab initio molecular dynamics simulations in the presence of an electrochemical bias to provide time scales for PFAS degradation on electrified surfaces. Taken together, the CEP-based quantum calculations provide critical reaction mechanisms for PFAS degradation in open electrochemical systems, which can be used to prescreen candidate material surfaces and optimal electrochemical conditions for remediating PFAS and other environmental contaminants.

A meta-analysis was performed by extracting and standardizing quantitative data from 97 microbial PFAS biotransformation studies and comparing outcomes via statistical tests. It indicated that the likelihood of PFAS biotransformation was higher under aerobic conditions, in experiments with defined or axenic cultures, when high concentrations of PFAS were used, and when PFAS contained fewer fluorine atoms in the molecule. The meta-analysis also documented that PFAS biotransformation depends on chain length, chain branching geometries, and headgroup chemistry. The literature is scarce or lacking in (i) anaerobic PFAS biotransformation experiments with well-defined electron acceptors, electron donors, carbon sources, and oxidation-reduction potentials; (ii) analyses of PFAS biotransformation products; and (iii) analyses to identify microorganisms and enzymes responsible for PFAS biotransformation. To date, most biotransformation research has emphasized 8:2 fluorotelomer alcohol, 6:2 fluorotelomer alcohol, PFOS, and PFOA. A wide array of PFAS remains to be tested for their potential to biotransform.

Brooks, M. ǀ Groundwater Forum monthly meeting, 6 March, 27 slides, 2025

An evaluation framework based on five lines of evidence was developed to help evaluate the potential significance of plume persistence due to back diffusion at groundwater contaminated sites. This framework was then used to construct a Bayesian network model that provides a quantitative prediction of the likelihood for back diffusion. The prediction relies on evaluating the strength or weakness of each line of evidence, which is assessed using site characterization data. The second research area concerns the forward diffusion of remedial amendment to degrade contaminants in the low permeability layer or zone (LPZ). While amendment injection has not traditionally been considered efficient when LPZs are present due to flushing limitations, it is important to recognize that flushing limitations may be minimized, or at least predicted, with design considerations that explicitly account for LPZ diffusive transport. The amendment will undergo back diffusion just like the contaminant, and it is important to ensure the residence time of the amendment in the LPZ is comparable to that of the contaminant under diffusive transport. These concepts are demonstrated using one-dimensional computer modeling, and a screening-level evaluation is being explored to aid in remedial designs. https://cfpub.epa.gov/si/si_public_record_report.cfm?dirEntryId=365109&Lab=CESER&simplesearch=0&showcriteria=2&sortby=pubDate&timstype=&datebeginpublishedpresented=06/15/2019&searchall=remediation+
