FRTR Fall 2026 General Meeting: Recent Developments in PFAS Remediation Technologies – Federal Remediation Technologies Roundtable
December 15, 2026, 8:00AM-5:00PM EST, 13:00-22:00 GMT
Introduction to the FRTR Fall 2026 Meeting
Understanding per- and polyfluoroalkyl substances (PFAS) toxicity, sampling, behavior in the environment and treatment has required sustained efforts in technology research, development, testing, and evaluation (RDT&E). Together with these efforts, effective technology transfer has been critical to providing remediation practitioners with best available tools and targeted remediation strategies for managing and restoring sites posing unacceptable risks. In recent years, FRTR meeting discussions have included PFAS-related topics such as "Source Differentiation and Risk Assessment"(Fall 2024), "PFAS Characterization Technologies" (Fall 2023), and "Emerging Characterization and Remedial Technologies" (Fall 2018). The pace of PFAS-related RDT&E has only increased since these earlier meetings and the PFAS knowledge base has expanded substantially.
Meeting Objective
The FRTR 2026 Fall Meeting, held in-person and virtually, focuses on advanced remediation technologies for PFAS. It provides an opportunity to share the expanding PFAS knowledge base and highlights progress in the rapidly evolving field of PFAS remediation. Invited speakers provide presentations and panel discussions to share accomplishments and new methodologies in key technical areas and discuss application of recent advances in characterization and remediation of PFAS-impacted sites. The morning session will focus on recent advances in PFAS characterization, fate, and transport. The afternoon session will build on these topics by exploring PFAS numerical modeling, technology transfer, and PFAS destruction technologies. http://www.clu-in.org/live/
Vapor Intrusion Mitigation (VIM-1) - A Two Part Series: Session 1 – Interstate Technology and Regulatory Council
October 22, 2026, 1:00PM-3:00PM EDT, 17:00-19:00 GMT
ITRC's Vapor Intrusion Mitigation training is a series of eight (8) modules, presented over two sessions. If you took the ITRC VIM series previously, the content has stayed the same, but the new course directs people to the Vapor Intrusion (VI) Toolkit resources published in January 2026 by ITRC.
The Vapor Intrusion Mitigation training series provides an overview of VIM and presents information from the 2026 Vapor Intrusion (VI) ToolkitITRC VI Toolkit (which includes fact sheets, technology information sheets, and checklists).
Session 1:
Introduction & Overview of Vapor Intrusion Mitigation Training Team
Conceptual Site Models for Vapor Intrusion Mitigation
Community Engagement During Vapor Intrusion Mitigation
Rapid Response & Ventilation for Vapor Intrusion Mitigation
Remediation & Institutional Controls
Session 2:
Active Mitigation Approaches
Passive Mitigation Approaches
System Verification, OM&M, Curtailment and Shutdown
When certain contaminants or hazardous substances are released into the soil or groundwater, they may volatilize into soil vapor. VI occurs when these vapors migrate up into overlying buildings and contaminate indoor air. The ITRC VI Toolkit combines the previous ITRC VI-related guidance documents (VI 2007, PVI 2014, VIM-1 2020), along with updates, into one comprehensive resource toolkit (including fact sheets, technology information sheets and checklists) published in January 2026.
After the Vapor Intrusion Mitigation series, you should understand:
How to locate and utilize the relevant document, fact sheets, technology information sheets, and checklists
The importance of a VI mitigation conceptual site model
How community engagement for VI mitigation differs from other environmental matters
When to implement rapid response for VI and applicable methodologies
The differences between remediation, mitigation, and institutional controls
Available technologies for active and passive mitigation, and design considerations for various approaches
How/when/why different mitigation technologies are appropriate
How to verify mitigation system success, address underperformance, and develop a plan for curtailment of a mitigation system and shutdown
We encourage you to use the ITRC VI Toolkit and these training modules to learn about VI mitigation and how you can apply these best practices to improve decision-making at your sites. For regulators and other government agency staff, this understanding of VI mitigation can be incorporated into your own programs.
While the training makes every effort to keep the information accessible to a wide audience, it is assumed that the participants will have some basic technical understanding of chemistry, environmental sciences, and risk assessment. As with other emerging contaminants, our understanding of VI mitigation continues to advance. This training provides the participants with information on areas where the science is evolving and where uncertainty persists.
ITRC: Introduction to Hydrocarbons – Interstate Technology and Regulatory Council
October 27, 2026, 1:00PM-3:00PM EDT, 17:00-19:00 GMT
Petroleum is a complex mixture of many compounds. Regulatory and technical guidance documents commonly focus on the hydrocarbon components of that mixture, or perceived risks that they present. However, focusing on a specific area of concern often causes practitioners to overlook other aspects of a release. For example, concerns related to exposure to total petroleum hydrocarbons (TPH) risks may be overlooked while pursuing concerns related to light non-aqueous phase liquid (LNAPL) recovery or petroleum vapor intrusion (PVI).
This class is designed to provide a basic overview of hydrocarbon behavior in the subsurface and how to scientifically assess concerns arising from the release of petroleum products into the environment. It will highlight key issues that help identify and manage TPH, LNAPL, and PVI risks together. Key concepts will include:
Fundamentals of petroleum hydrocarbons
Petroleum chemistry
How TPH, LNAPL, and PVI are related
Building an integrated conceptual site model (CSM)
What is a CSM…what is its purpose?
When is a CSM complete?
Identifying and managing the risks from petroleum hydrocarbons
Defining LNAPL risks based on acute, saturation, composition, or aesthetic concerns
Emphasize the importance of biodegradation in risk management decision making
How to select remedial goals and remedies that align with your goals
This course is based upon three separate Guidance Documents developed by ITRC that address the course content in detail:

PFAS Sorption Based Technologies for Separation & Concentration of PFAS from Water – Interstate Technology and Regulatory Council
November 12, 2026, 1:00PM-3:00PM EST, 18:00-20:00 GMT
Removal of PFAS from water has become an important concern for water utilities; landfill operators; industry professionals; and state, local, and tribal decision makers. Sorption-based technologies, specifically granular activated carbon, ion exchange resins, and foam fractionation have proven to be effective solutions in this area, but choosing the most suitable sorption-based method or system configuration can be daunting. To aid treatment practitioners, the ITRC PFAS team published a technical guidance document titled "Sorption-based Technologies for Separation and Concentration of PFAS from Water" (Section 18 of PFAS-1). This training module is intended to assist in using the information presented in this document by providing an overview of the central topics along with easily digestible summaries of critical information.
Resources and further details for the topics included in this training are available in the ITRC PFAS-1 guidance document, specifically in Sections 12 and 18.
Learning objectives:
Review operating principles of sorption-based technologies.
Understand how site conditions and treatment objectives influence technology selection.
Become familiar with testing methods (from foamability tests to isotherm tests to full-scale demonstration tests) used to verify treatment effectiveness, optimize performance, and compare technologies.
Identify water quality parameters that may adversely affect sorption-based technologies and the available pretreatment methods to address them
Learn how test data can be combined with cost and sustainability information to select a specific technology or system configuration.

It will provide an overview of mitigation strategies, including various closure strategies, land use covenants, and institutional controls.
Session 1 will focus on:
What is Vapor Intrusion
VI Exposure Pathway
VI in Practice - including common CSMs, Scenarios, and Chemicals
Potential Limiting Factors for VI - PVI vs Chlorinated VI, Geology, Hydrogeology, and Building Operating Conditions
How is VI Different & Challenges in Evaluating VI
