• ITRC: Contaminants of Emerging Concern (CEC) Identification Framework – Interstate Technology and Regulatory Council
  October 1, 2026, 1:00PM-3:00PM EDT, 17:00-19:00 GMT
  In 2023, the ITRC Contaminants of Emerging Concern (CEC) Framework was published to help environmental regulatory agencies and other stakeholders identify, evaluate, and manage CEC's while acknowledging uncertainties in their environmental fate and transport, receptor exposure, and/or toxicity. Such an approach can be conducive to improved allocation of regulatory response resources and provide a foundation for communicating potential risk to stakeholders.

  The ITRC framework is comprised of a white paper and four associated fact sheets. In the white paper, CEC are defined as: "substances and microorganisms including physical, chemical, biological, or radiological materials known or anticipated in the environment, that may pose newly identified risks to human health or the environment." The framework is meant to help environmental regulatory agencies and other stakeholders by providing examples of CEC monitoring programs and guiding the user through the process of identifying CEC key characteristics, how to communicate real and perceived risk from CEC to the public, and how laboratory analytical methods can be used in the identification process.

  The ITRC CEC training presents this entirely new framework for identification, prioritization, and communication of CEC. This course includes the following topics:

  1. An overview of the framework, how and why it was developed, the factors that influence the creation of CEC management units at the state level, and a listing of existing CEC monitoring programs.
  2. A discussion of key variables that may be used as criteria to identify and prioritize CEC for response actions. This portion of the course includes a case study that illustrates how the identification and prioritization process works with an "unknown" chemical CEC.
  3. Practices and methods for stakeholder messaging and how to share incomplete information on CEC that could impact human health and the environment. This portion of the short course builds upon the ITRC Risk Communication Toolkit by providing additional detail addresses communications plans, message maps, and audience identification.
  4. A paradigm for how laboratory methods can be used to identify CEC ranging from:
     • "Is compound X in the sample and at what concentration?" (i.e., known knowns) to
     • "Which compounds from the list are in this sample?" (i.e., known unknowns) to
     • "What is in the sample?" (i.e., unknown unknowns).

  CEC are typically compounds or substances whose occurrence or effect is unknown but may or may not be understood through similar compounds or substances. This module includes a discussion of the use of targeted and untargeted analysis to identify a CEC.

  Participants will learn the elements of the CEC framework and gain an understanding of the framework application from case studies. Participants are encouraged to review the ITRC CEC Framework prior to the class.

• ITRC: Microplastics – Interstate Technology and Regulatory Council
  October 8, 2026, 1:00PM-3:00PM EDT, 17:00-19:00 GMT
  In response to one of the biggest emerging environmental concerns, ITRC formed the Microplastics Team in 2021 to develop the Microplastics Guidance Document. Plastics have become pervasive in modern life and are now used in a wide range of commercial and industrial applications. Microplastics may result from the degradation and fragmentation of larger plastics, or they may be intentionally produced for specific applications and products. Regardless of their origin, microplastics are now ubiquitous in our environment. Because of their small size and pervasiveness in the environment, microplastics, along with any other contaminants which are adhered to the microplastics, may be inadvertently consumed by humans and other organisms.
  
  The online ITRC Guidance Document is geared toward an audience with reasonable level of scientific understanding, but not microplastic-specific knowledge. The guidance provides a user with information on microplastics and the state of the applied science without having to go to the scientific literature.
  
  The target audience for the guidance and this training course includes state regulators and environmental consultants, as well as community and tribal stakeholders.
  
  The guidance and this associated training course uses a conceptual site model to navigate microplastics in the environment and explore the following general areas:
  • An introduction to microplastics, their sources, and worldwide distribution
  • The pathways through which microplastics can enter and travel in the environment and their distribution in various media (water, soil, sediment, air, and biota)
  • A current look at the most common techniques and best practices for sampling and analyzing microplastics
  • Potential human health and ecological risks associated with microplastics in the environment
  • An overview of existing regulations related to microplastics and macroplastics at the state, federal, and international levels
  • Examples of prevention and mitigation strategies and best management practices to reduce microplastics from entering the environment and the emerging technologies to abate, treat, and remediate microplastics once they exist in the environment
  • Identification of data gaps and the need for further research
  • Several case studies illustrating a range of current microplastics-related topics
  Prior to attending the training class, participants are encouraged to view the associated ITRC Microplastics Guidance Document.

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:

• Light Non-Aqueous Phase Liquid (LNAPL), LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3)
• Petroleum Vapor Intrusion (PVI), Fundamentals of Screening, Investigation, and Management (PVI-1)
• Total Petroleum Hydrocarbon (TPH), TPH Risk Evaluation at Petroleum-Contaminated Sites (TPHRisk-1)

Vapor Intrusion Mitigation (VIM-1) - A Two Part Series: Session 2 – Interstate Technology and Regulatory Council
November 3, 2026, 1:00PM-3:00PM EST, 18:00-20:00 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 ITRC 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.
