Forensic Data Science for PFAS Investigations: Tools, Workflows, and Case Studies in R
*Laptop Required Course
Instructor: Mike Dereviankin (Environmental Standards Inc.)
This course will introduce participants to modern chemometric and data science techniques for interpreting per- and polyfluoroalkyl substances (PFAS) datasets in environmental forensics. Attendees will learn to process, visualize, and statistically model PFAS patterns using R to support source attribution and forensic interpretation. Emphasis will be placed on practical workflows, reproducible analyses, and defensible visualization strategies using the real-world dataset as a foundation.
Course Overview:
The forensic investigation of PFAS requires a shift from traditional chemical interpretation toward data-driven statistical approaches. Modern analytical instrumentation generates complex, high-dimensional datasets, and effectively decoding these signatures is key to distinguishing background influences from point-source releases. This course is designed to equip environmental professionals with the computational and statistical tools to interpret PFAS data quantitatively and defensibly.
Participants will be introduced to the principles of chemometrics, the application of multivariate statistical and machine learning methods to chemical datasets, through hands-on exercises in R. The course will emphasize workflows for data cleaning, transformation, outlier detection, and imputation, enabling participants to prepare real-world PFAS datasets for advanced analysis.
Building on these foundations, attendees will explore dimensionality reduction (PCA, t-SNE, UMAP) to visualize relationships among samples and clustering algorithms (K-means, hierarchical analysis) to uncover natural groupings in PFAS fingerprints. The course will also demonstrate quantitative source apportionment techniques, including positive matrix factorization (PMF), non-negative matrix factorization (NMF), and alternating least squares (ALS), with case studies illustrating their role in differentiating aqueous film forming foam (AFFF)-related, industrial, and regional background signals.
A central component of the workshop is the UCMR 5 dataset (EPA, 2023), which serves as a national reference for PFAS occurrence in drinking water. Participants will learn to benchmark local or site-specific data against UCMR 5 distributions, identify anomalous or site-specific fingerprints, and communicate these findings through clear, reproducible graphics built in ggplot2 and R Markdown.
By the conclusion of this course, attendees will have gained the ability to:
- Implement a reproducible data science workflow for PFAS forensics using open-source tools.
- Apply multivariate and machine-learning methods for source differentiation and uncertainty interpretation.
- Communicate chemometric results effectively through visual and statistical narratives suitable for technical and regulatory audiences.
Sunday, May 31, 8:00 a.m.-5:00 p.m.
*CANCELLED* Geochemical Modeling in Practice: Fundamentals to Advanced Applications
Course Objective:
This applied geochemical modeling course will aim to:
1) Help participants understand the fundamentals of geochemical modeling, covering three broad classes of models: speciation, reaction path, and reactive transport
2) Give numerous case study examples illustrating how geochemical models can be used to solve problems in remediation
3) Provide attendees with sufficient background and conceptual knowledge to initiate development of standalone geochemical models or integrated transport and reactivity models.
Course Overview:
This practical workshop will equip attendees with a clear understanding of geochemical modelling principles, methods, and applications. Participants will explore the three primary geochemical modeling archetypes: speciation, reaction path, and reactive transport modelling as well as the basic geochemical principles and concepts that are used to develop each model type. These concepts include thermodynamic equilibrium and kinetic rate laws, aqueous speciation and activity models, mineral saturation and precipitation, gas equilibria, sorption/attenuation reactions, redox equilibria, and microbial metabolism. The course will explore some of the basic tools used to support these models including thermodynamic databases, water chemistry plots and Eh/pH diagrams and presenters will discuss required input data types and differences between commonly used modeling codes (e.g., PHREEQC and The Geochemist's Workbench).
The initial conceptual session will be followed by real world case study examples of geochemical models used to solve problems across the remediation project life cycle. Examples include monitoring well scaling, precipitation of amorphous solids and contaminant attenuation, aquifer compatibility and compliance, and sorption and breakthrough curves in a contaminant plume.
The workshop will cover conceptual model development, modelling approaches, and key considerations when selecting model types. Attendees will also gain insight into advanced techniques such as machine learning applications (and differences between data driven and mechanistic approaches) and complex conceptual model development.
The course is designed for professionals seeking to understand the capabilities and limitations of geochemical modeling to support their use in remediation project decision making. The workshop is suitable for a range of participants, including geochemists desiring to make a conceptual start to geochemical modeling, hydrogeologists who want to understand how geochemistry and transport models can be integrated, and project managers and technical leaders who require an overview of when geochemical prediction is necessary to meet remediation objectives.
Sunday, May 31, 8:00 a.m.-12:00 p.m.
*CANCELLED* An Introduction to the ASTM Standard E3488-25, Standard Guide for Moving Sites to Closure (MStC) for Petroleum Underground Storage Tank (UST) Releases
Course Objective:
The short course will introduce the participants to the Moving Sites to Closure (MStC) standard guide and demonstrate its application through a series of exercises with example sites. The workshop is intended for UST owners, corrective action professionals, and regulators who wish to learn how they can apply MStC principles at individual sites, as well improve regulatory policy.
Course Overview:
Nationwide there are approximately 55,000 petroleum UST release cleanups that have not been completed. This “corrective action backlog” has been decreasing slowly during the last 10 years; however, many cleanup experts believe that most of these backlog sites may no longer pose a significant threat to human health and the environment even though they do not meet the current cleanup standards. ASTM’s E50.04 Subcommittee on Corrective Action formed a Task Group to gather the latest scientific literature regarding how petroleum behaves underground and best management practices for moving sites to closure. The Task Group, with the help of ASTSWMO, surveyed states’ current practices regarding alternative closure criteria and the current barriers to closure. ASTM published a standard guide, E3588-25, in September 2025 which provides a new framework for moving petroleum UST releases to closure. The framework includes alternative closure criteria for verifying sites no long pose a threat, and best practices to overcome non-technical barriers and reevaluating ongoing corrective actions.
Sunday, May 31, 8:00 a.m.-12:00 p.m.

*CANCELLED* Stable Isotope Techniques: Unlocking Insights into the Performance of In Situ Remediation Treatments Addressing Organic Contaminants
Instructor: Daniel Bouchard, GHD; Kammy Sra, Chevron; David Alden, Tersus Environmental; Orfan Shouakar-Stash, Isotope Tracer Technologies Inc.; Ravi Kolhatkar, Stantec
Course Objective:
This workshop will introduce the fundamentals of stable isotope methods to describe state-of-the-art applications, depict field implementation strategies for robust site assessments, and expose all types of information that can be obtained during field site assessments.
Field cases covering diverse in situ remediation treatments will be provided and discussed to highlight the value of stable isotopes as a diagnostic tool to monitor remedial performance and the lessons learned. This introductory course is intended for regulators, site owners, field practitioners, consultants and young scientists.
Course Overview:
Over the last three decades, compound-specific isotope analysis (CSIA) has evolved from a research concept into a powerful field assessment tool to document source signatures and transformation processes for organic contaminants, such as petroleum hydrocarbons and chlorinated solvents (EPA, 2008). Application of CSIA as a characterization tool has been thoroughly studied through numerous scientific review publications and textbooks, and then related to field practitioners by environmental agencies and working groups (EPA, 2008; Aelion et al., 2010; Jochman and Schmidt, 2012). Over time, the method has become cost effective and is now increasingly used by field practitioners to gain key information on origin and fate of the COC that traditional methods based on concentration analysis are unable to reveal.
CSIA is a process-based advanced characterization tool that tracks the stable isotope composition (13C/12C, 2H/1H or 37Cl/35Cl, ratios) of selected compounds present in groundwater. Based on these isotopic ratios, the tool can be used to differentiate sources of the same contaminant present in the subsurface (forensic investigations). When tracking the ratio evolution over distance or time, the tool has proven its reliability in demonstrating in situ biological destruction of organic compounds in groundwater, thus becoming an important line of evidence in the framework of a monitored natural attenuation program (EPA, 2008; Kuntze et al., 2019) or for enhanced attenuation (Kolhatkar and Schnobrich, 2017). More recently, CSIA has been applied to in situ remediation treatments. With CSIA being able to discriminate between co-occurring mass removal processes, application of CSIA during an engineered in situ remediation thus represents a great asset in assessing in situ treatment performance (Bouchard et al., 2018; Bouchard et al., 2024). In addition, assessing inorganic forms for other stable isotopes can also reveal valuable information. Change in 13C/12C ratio for dissolved inorganic carbon becomes an indicator of complete organic compound mineralization, whereas sulfur (34S/32S) (Sra et al., 2023) and nitrogen (15N/14N) (Deb et al., 2025) isotope ratios are used to support presence of microbial activity at sites by assessing the fate of sulfates and nitrates, respectively, when added as electron acceptors.
Sunday, May 31, 1:00-5:00 p.m.
Environmental Forensics-Past, Present and Future Developments
Instructor: Richard Philp, University of Oklahoma (Emeritus)
Course Objective:
This course will expose environmental scientists, regulators, engineers, and attorneys to the field of environmental forensics. The course will include a discussion of how the concept has evolved over the years along with the analytical techniques utilized in forensic investigations. Applications involving contaminants such as crude oils and refined products, chlorinated solvents, PFAS, dioxane, and EDB will be discussed.
Course Overview:
Environmental forensics has become an important area of research since the early 1970s. Interest was driven by development in analytical technology and greater awareness of environmental issues. The basic premise remains the establishment of the relationship between contaminant and possible sources. Since the 1970s, there have been major advances in analytical techniques in terms of sensitivity, selectivity, and specificity. The range of contaminants of concern has also greatly expanded. The 1970s saw hydrocarbon releases being of major interest but since that time interest has expanded to MTBE, chlorinated solvents, PBDEs, pesticides, PFAS, EDB, 1,4-dioxane and many other persistent pollutants in air, soil, and water.
This course will discuss what an environmental forensic expert needs to investigate these environmental incidents. A good understanding of analytical chemistry and fate of products after release into the environment are essential since the fingerprints of the contaminant may be quite different from the product in the storage tank. An understanding of the manufacturing processes involved in synthesis of the contaminants can also be extremely useful. Historical changes in product composition resulting from manufacturing processes or end use specifications are critical areas of environmental forensics.
Preliminary characterization of the environmental samples is undertaken by gas chromatography (GC) followed by more detailed analyses using gas chromatography-mass spectrometry (GC/MS) and possibly MS/MS along with 2-D GC. Stable isotope composition of individual contaminants, including C, H, N, Cl, Br, or S isotopes, can be utilized for single components where GC and GC/MS are of little use for correlation or differentiation.
This course will present evolution of these techniques and applications to environmental forensic problems. Integration of historical product information, site histories and other information will also be discussed. The ultimate goal of the course is toi provide a comprehensive picture of what is required to be an environmental forensic expert or scientist.
Sunday, May 31, 1:00-5:00 p.m.
*CANCELLED* Introduction to 3-D Visualization and Contaminant Modeling in Leapfrog Works
*Laptop Required Course
Instructor: Lucas Snedeker, Seequent; Sean Buchanan, Seequent; Atef Hamdan, Seequent
Course Objective:
This hands-on course will empower environmental professionals to build confidence in using Leapfrog Works for subsurface visualization and contaminant modeling. Whether working on site remediation, groundwater investigations, or environmental impact assessments, this course will help the attendee unlock the full potential of 3-D environmental modeling.
Course Overview:
The Leapfrog Works short course on contaminated land and groundwater will offer a comprehensive, hands-on introduction to 3-D geological modeling tailored for environmental professionals. Designed for geologists, environmental professionals, hydrogeologists, and engineers working in remediation and site characterization, the course will guide participants through the full modeling workflow—from mastering the user interface, to producing geologic and numeric models and detailed cross sections that support decision-making.
The course will begin with an orientation to the Leapfrog Works interface, emphasizing intuitive navigation, data import workflows, and project organization. Participants will visualize borehole and geochemical data to assess preliminary site conditions. The training then will progress to building geological models that incorporate lithological interpretations. These models form the foundation for understanding contaminant pathways and distribution within the site. A key focus of the course will be the integration of numeric modeling, particularly for subsurface contamination. Attendees will learn to generate contaminant plumes, visualize concentration gradients, and understand volume distributions of contaminants of concern. Finally, participants will be guided through the creation of cross sections and visual outputs that communicate complex subsurface conditions clearly and effectively. These deliverables are essential for stakeholder engagement, regulatory reporting, and remediation planning. By the end of the course, attendees will have developed a complete contaminated land model, gaining confidence in using Leapfrog Works to support environmental investigations and remediation strategies.
Sunday, May 31, 1:00-5:00 p.m.
*CANCELLED* Total Oxidizable Precursor Assay Explained
*Laptop Required Course
Instructor: Dora Chiang, Jacobs; Jenny Zenobio, Jacobs; Tiffany Hill, Jacobs; Chris Heron, Jacobs; Sid Park, Jacobs
Course Objective:
The total oxidizable precursor (TOP) assay is increasingly used to characterize PFAS precursors in environmental samples to verify the presence and abundance of nontarget PFAS, evaluate precursor transformation, assess PFAS risk, and measure treatment performance. This short course will introduce TOP assay, guide the interpretation of TOP data, and explore how to optimize its use to better understand precursor fate and transformation. The course also addresses its limitations and uncertainties associated with sample matrices, analytical interferences, and inherent data constraints.
Course Overview:
An increased number of PFAS precursors have been manufactured, used and released to the environment over decades. PFAS fate, transport and treatment have largely been characterized using USEPA-certified PFAS methods that quantify a limited number of PFAS (such as USEPA Method 1633 for 40 PFAS). However, this target list does not capture the full breadth of PFAS present in environmental samples, creating a growing demand to expand analytical coverage so practitioners can more confidently identify and report a broader range of PFAS species and concentrations.
While analyte expansion is underway, the need to understand PFAS precursors’ abundance, transformation behavior, and degradation is rapidly growing. Nontarget and suspect-screening methods using high-resolution mass spectrometry have been developed by academic researchers to identify, and semi-quantitatively measure suspect PFAS. However, data quality and interpretation can vary widely among laboratories, and the analytical complexity typically results in extended turnaround times and significantly higher analytical costs.
TOP assay, in contrast, is commercially available, and widely used to quantify oxidizable precursors by converting them to measurable perfluoroalkyl acids (PFAAs; PFCAs or PFSAs). However, TOP assay results remain a specialized dataset typically interpreted only by PFAS subject matter experts and is not well understood by remediation practitioners. This short course is designed to accelerate understanding and application of TOP assay data.
Tuesday, June 2, 2:00-6:00 p.m.
Combining ISS and ISCO: Best Practices and Lessons Learned
Instructor: Brant Smith, Evonik Corporation; Josephine Molin, Evonik; Tony Moran, ENTACT, LLC; Christopher Robb, Geosyntec Consultants, Inc.; Isabel Peter Rando, Arcadis
Course Objective:This course will inform participants of critical aspects of the combined remedy of ISCO-ISS. These include fundamental chemistries, key synergies, how to go about a design and bench test, application methods, and lessons learned from those that have previously implemented the technology.
Course Overview:
In situ solidification/stabilization (ISS) and in situ chemical oxidation (ISCO) are well-established remediation technologies that have been used to treat contaminated sites around the world for several decades. It has been found that these technologies can be readily combined in a single application where the advantages of each technology can help offset the disadvantages of the other.
Generally, ISS involves the addition of binders such as Portland cement to reduce the spread and leachability of contaminants by reducing the soil's hydraulic conductivity, decreasing pore space, and encapsulating the contaminants in a solidified monolith while providing the desired soil strength. While being a field proven technology, in an ISS only remediation approach, contamination is left in place maintaining the environmental liability. The addition of binders or other volumetric additive can cause soils to swell (increase in volume), which may require additional treatment, disposal of the excess soils in a landfill or additional onsite grading.
ISCO is effective via a different mechanism, reacting with and degrading organic contaminants to permanently reduce site risk. ISCO can be costly at very high contamination levels and soil mixing with ISCO only can leave soils loose with insufficient strength for redevelopment or, in some cases, preventing site access for months (or even years) after an application.
In recent years, a combination of these two technologies has increased in popularity for heavily contaminated sites or sites where rapid post application access is desired. This approach demonstrates a true combined remedy where two technologies contribute to remediating a site via distinctly different mechanisms resulting in a more complete and cost-effective solution as opposed to applying either technology by itself.
Key elements of each technology and the combined remedy that will be presented include:
• Fundamental elements of each technology
• Chemistry behind the combined remedy
• Benefits and key synergies of the combined remedy
• Health and safety considerations
• Bench study design and implementation
• Application design
• Soil mixing methods and strategies
• Monitoring
• Lessons learned during field application
• Case studies
This short course will be equally weighed between theoretical, laboratory, and field generated information. The structure will include two presentations on theoretical and laboratory aspects of ISCO-ISS and then practitioners walking through their site-specific experiences from bench to field.
Those attending this session should obtain an understanding of critical design elements, reagent characteristics, appropriate bench tests, health and safety, and application methods.
The session will allow for open discussion with the presenters including the decisions made on actual sites.
Tuesday, June 2, 2:00-6:00 p.m.

Tuesday, June 2, 2:00-6:00 p.m.
*CANCELLED* Designing for Long Term In-Situ Remediation Performance: Integrating Subsurface Transport, Reagent Longevity, and Emplacement Mechanics
Instructor: Lowell Kessel, CERES Remediation Products
Course Objective:
This course will provide a framework to diagnose critical challenges or limitations to in situ remediation performance at groundwater sites and utilize those limitations as the design basis. This is accomplished first by quantifying the physical site limitations like Fickian (back-diffusion) and Darcy (bypass) flux, next by evaluating the optimal injection approach and available modifiers or enhancement techniques, and finally, by selecting the optimal reagent mixture that matches reagent physical properties and life-cycle performance with the selected injection method.
Course Overview:
The Problem: Temporal Mismatch & Mass Transfer Limitations
This technical course will analyze the primary cause of in situ remediation failure: a fundamental mismatch in the "fourth dimension" (time). Remediation projects stall when the contaminant flux timeframe, particularly from low-permeability zones, far exceeds the reagent's active lifespan. This course will move beyond standard fate and transport to quantify why these remedies fail. This involves calculating contaminant mass sequestered in low-K zones and the rate of its release via Fickian flux (back-diffusion), which is often the true rate-limiting step for site closure. Presenters will analyze how conventional strategies fail by not addressing this mass, which is often bypassed by advective flow (Darcy flux) through more permeable, preferential pathways, leading to contaminant rebound.
The Engineering Framework: Matching Reagents and Emplacement to the Site
This course will present a "physics-first" design framework that subordinates reagent chemistry to the site's physical limitations. It will demonstrate how to use the conceptual site model (CSM) to quantify these limitations and engineer the optimal approach inclusive of the fourth dimension. Participants will learn to calculate critical transport parameters from geotechnical data (e.g., (ρb, η, foc) and chemical properties to determine the Retardation Factor, Koc and Effective Diffusion Coefficient (Dc = Daq •ф•τ).
These metrics, not just contaminant concentration, dictate the remedial design. The course will then detail the principles, limitations, and applications of various emplacement methods, from low-pressure permeation to higher pressure injections, and show how to select the appropriate technique. The course will cover how to "engineer" the reagent formulation—matching its physical properties (e.g., soluble, colloidal, granular, viscosity) and chemical longevity (fast-release versus slow-release donors) to the chosen emplacement method and the site's geology.
Application & Case Studies: A Predictable Path to Closure
The workshop emphasizes the influence of injection methods on the spatial distribution, longevity, and reactivity of injected materials, which are critical factors in achieving successful bioremediation (e.g., microbial degradation of organic pollutants) and chemical reduction (e.g., reductive dechlorination of chlorinated solvents). Case studies and real-world examples will illustrate how injection strategies can be optimized to overcome site-specific challenges, such as heterogeneous subsurface conditions or recalcitrant contaminants. Additionally, the session will explore the interplay between injection techniques and microbial activity, highlighting how proper delivery methods can enhance microbial colonization and metabolic processes. Attendees will gain a deeper understanding of how to select and design remediation injections tailored to specific remediation goals, ensuring improved performance and cost-effectiveness. This knowledge will empower environmental professionals to implement innovative solutions for tackling complex contamination scenarios, ultimately contributing to more sustainable and effective remediation outcomes.

The objective of this course is to familiarize participants with 1) borehole geophysical methods most useful for hydrogeologic characterization of overburden and fractured bedrock, 2) additional methods for hydrogeologic characterization of fractured bedrock, 3) the different types of multilevel groundwater monitoring well systems, and 4) the design of multilevel wells using borehole geophysical logs and other hydrogeologic data.
Course Overview:
The course will review borehole geophysical methods used to characterize overburden and fractured bedrock, following guidance from the U.S. Geological Survey (USGS) and the Interstate Technology Regulatory Council (ITRC) Characterization and Remediation in Fractured Rocks team. The use of nuclear magnetic resonance (NMR) for characterizing overburden and transition zones—from unconsolidated material through saprolite, and weathered bedrock—will also be discussed. Geophysical methods covered will include caliper, natural gamma, optical televiewer (OTV), acoustic televiewer (ATV), fluid temperature, fluid conductivity, electromagnetic induction, and electrical resistivity. The course will review how these logs are analyzed in the field to guide subsequent flowmeter logging (using heat pulse, spinner, and electromagnetic tools). The importance of lining boreholes with a blank FLUTe liner will also be emphasized. Additional methods for characterizing open boreholes in fractured bedrock—such as packer testing, FLUTe FACT, FLUTe transmissivity profiling, NAPL liners, and various groundwater sampling techniques—will be covered. An example of how data from multiple sources can be compiled in WellCAD software to create an integrated borehole geophysical log will be presented. Participants will also review the various types of multilevel groundwater sampling systems currently available including their capabilities, advantages, and limitations, and their application in both overburden and fractured bedrock settings. The integrated borehole geophysical log will be used to demonstrate the design of a multilevel well. Lastly, the course will review and evaluate the construction process for different multilevel well systems and discuss subcontract specifications for borehole geophysical investigations and multilevel well installation.
