Upcoming Internet Seminars

  • Evaluating and Integrating Cumulative Environmental Impacts in Superfund Human Health Risk Assessments¬†U.S. EPA Office of Land and Emergency Management
    July 23, 2024, 3:00PM-4:30PM EDT, 19:00-20:30 GMT
    Superfund uses a risk-based decision framework to assess and manage human exposure to a release and the threat of a release in the environment from pollutants and contaminants. The risk assessment process quantifies the baseline risk from route of exposure (e.g., inhalation, ingestion, etc.) and the toxicity (e.g., cancer and noncancer). Furthermore, when information such as toxicity is not available, the risk assessment may provide a qualitative assessment to inform the risk manager towards a protective remedy. An important aspect is identifying at-risk populations that may be more susceptible to adverse health outcomes due to their vulnerability and sensitivity (e.g., children). However, Superfund has not issued national guidance on how to incorporate or consider concurrent exposure to factors such as psychosocial stress, racial/minority status, low-income and food insecurity, which have been shown to modify risks from chemical releases for at-risk communities. Executive Order 12898 requires EPA to identify and address, as appropriate, disproportionately high and adverse human health or environmental effects of its programs, policies and activity on minority and low-income populations to the greatest extent possible. This webinar will provide an overview of the following topics: superfund risk assessment, chemical stressors, non-chemical stressors, Environmental Justice, screening tools, and superfund site case studies.

  • Overview of Radiation and Chemical Ecological Risk Assessment Models and Guidance for Contaminated Sites and Selected Default Input ParametersU.S. EPA Office of Land and Emergency Management (OLEM), Office of Superfund Remediation and Technology Innovation (OSRTI)
    July 25, 2024, 2:00PM-3:30PM EDT, 18:00-19:30 GMT
    To help meet the U.S. Environmental Protection Agency (EPA) Superfund program's mandate to protect human health and the environment from current and potential threats posed by uncontrolled hazardous substance (both radiological and non-radiological), pollutant, or contaminant releases, the Superfund program has developed an ecological risk assessment process as part of its remedial response program. This webinar will describe the process and results from a research project concerning factors that could potentially attribute to adverse ecological risk for biota due to radioactive contamination in soil or water at or near Superfund sites. This project reviewed models and guidance on assessing protection of biota to exposures from contamination at sites issued or recommended by federal, state, and foreign governments.

  • Vapor Intrusion Mitigation (VIM-1) - A Two Part Series: Session 1Interstate Technology and Regulatory Council
    September 19, 2024, 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.

    The Vapor Intrusion Mitigation training series provides an overview of vapor intrusion mitigation and presenting information from the ITRC fact sheets, technology information sheets, and checklists (VIM-1, 2021):

    Session 1:
    • Introduction & Overview of Vapor Intrusion Mitigation Training Team
    • Conceptual Site Models for Vapor Intrusion Mitigation
    • Public Outreach 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, and Exit Strategies


When certain contaminants or hazardous substances are released into the soil or groundwater, they may volatilize into soil gas. Vapor intrusion (VI) occurs when these vapors migrate up into overlying buildings and contaminate indoor air. ITRC has previously released guidance documents focused on VI, including the "Vapor Intrusion Pathway: A Practical Guidance" (VI-1, 2007) and "Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management" (PVI, 2014). However, ITRC has received multiple requests for additional details and training on mitigation strategies for addressing this exposure pathway.

The ITRC Vapor Intrusion Mitigation Team (VIMT) created ten fact sheets, 16 technology information sheets, and 4 checklists with the goal of assisting regulators during review of vapor intrusion mitigation systems, and helping contractors understand the essential elements of planning, design, implementation, and operation, maintenance and monitoring (OM&M) of mitigation systems.

After the Vapor Intrusion Mitigation series, you should understand:
  • How to locate and utilize the VIM-1 fact sheets, technology information sheets, and checklists
  • The importance of a VI mitigation conceptual site model
  • How public outreach for VI mitigation differs from other environmental matters
  • When to implement rapid response for vapor intrusion 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 discontinuing a mitigation system

We encourage you to use the ITRC Vapor Intrusion Mitigation work products (VIM-1) and these training modules to learn about vapor intrusion 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 vapor intrusion 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 vapor intrusion mitigation continues to advance. This training provides the participants with information on areas where the science is evolving and where uncertainty persists.

  • ITRC: Pump & Treat OptimizationInterstate Technology and Regulatory Council
    September 24, 2024, 1:00PM-3:00PM EDT, 17:00-19:00 GMT
    ITRC's Pump & Treat (P&T) Optimization training aims to summarize existing information and best practices while also developing a systemic and adaptive optimization framework specifically for P&T well-network design and management.

    P&T systems have been one of the most commonly used methods for hydraulic containment and treatment of contaminated groundwater at sites with large groundwater plumes. This method cleans up groundwater contaminated with dissolved chemicals by pumping groundwater from wells to an above-ground treatment system that removes the contaminants. Optimization of P&T remedies is important for maintaining contaminant removal effectiveness throughout the operation lifetime and managing the system toward an exit strategy. A strategy for routine optimization of P&T remedies is key for maintaining the contaminant removal efficiency of these systems.

    The primary audience for this training is environmental project decision-makers, which may include federal, state, tribal, and various local agency employees; contractors to these agencies; and potentially liable parties and their engineers and consultants as well as involved stakeholders. Generally, those involved in designing, building and operating, and optimizing pump & treat systems would benefit.

    The goal of the training is to provide a roadmap for optimizing a P&T system and refining the remedial strategy or shifting toward another remedial approach. Pump & Treat optimization should be systematic and data-based, and the training and document aim to provide tools and direction to assist in this rigorous process.

    Key Takeaways

    • Understanding the P&T project lifecycle: evaluation, optimization, and transition, as well as considerations for sustainability, resiliency, and regulatory and stakeholder entities.
    • P&T optimization should incorporate adaptive site management.
    • P&T systems are influenced by a diverse collection of outside factors, which should be considered throughout the entire optimization process.
    • Transition and termination should both be considered during the optimization process.
    • Remedial objectives dictate evaluation and optimization efforts for P&T systems..

    Prior to attending the training class, participants are encouraged to view the associated ITRC Pump & Treat guidance document

  • ITRC: Optimizing Injection Strategies and In situ Remediation PerformanceInterstate Technology and Regulatory Council
    October 8, 2024, 1:00PM-3:15PM EDT, 17:00-19:15 GMT
    In 2020, ITRC recognized that In situ remediation technologies using amendment injections have advanced to mainstream acceptance and offer a competitive advantage over many forms of ex situ treatment of soil and groundwater. Developing a detailed site-specific strategy is absolutely critical to the success of such in situ remedies. These strategies include conducting a thorough site characterization that will allow development of a detailed Conceptual Site Model (CSM) to guide critical analysis of subsurface features and improving remediation effectiveness. In the interest of developing expedited solutions, many past in situ remediation projects have been executed based on an incomplete understanding of the hydrogeology, geology, and contaminant distribution and mass. Some of these sites have undergone multiple rounds of in situ injections but have not advanced to closure. Better strategies and minimum design standards are required to decrease uncertainty and improve remedy effectiveness.

    In an effort to overcome these challenges and improve the effectiveness of in situ remediation using injected amendments, ITRC developed the guidance: Optimizing Injection Strategies and In Situ Remediation Performance (OIS-ISRP-1). The guidance and this associated training course identify challenges that may impede or limit remedy effectiveness and discuss the potential optimization strategies, and specific actions that can be pursued, to improve the performance of in situ remediation by:
    • Refining and evaluating remedial design site characterization data;
    • Selecting the correct amendment;
    • Choosing delivery methods for site-specific conditions;
    • Creating design specifications;
    • Conducting performance evaluations, and
    • Optimizing underperforming in situ remedies.


    The target audience for this guidance and training course is: environmental consultants, responsible parties, federal and state regulators, as well as community and tribal stakeholders. This training will support users in efficiently and confidently applying the guidance at their remediation sites. An optimization case study is shared to illustrate the use of the associated guidance document.

    Prior to attending the training class, participants are encouraged to view the associated ITRC guidance, Optimizing Injection Strategies and In Situ Remediation Performance (OIS-ISRP-1) as well as to be familiar with the characterization process described in Integrated DNAPL Site Strategy (ITRC 2011c).

    The ITRC Managed Aquifer Recharge (MAR-1) Training is intended for state regulators and stakeholders who may not be familiar with the opportunities and challenges associated with MAR. It provides a basic understanding of MAR concepts, along with case studies, that showcase examples of successful MAR applications. For those who are familiar with MAR, the training gives an overview of the components of the MAR process along with the important considerations associated with each component necessary for the design and implementation of a MAR project. It is important to understand that MAR is an area of active research and expanding practical applications, and that this management process is continuing to evolve with time.

    The combination of climate change and growing demand for fresh water has resulted in an increase in the vulnerability and scarcity of freshwater supplies around the world. The need for fresh water to grow crops and provide for the welfare of the general population, economic growth, and ecosystems is becoming more acute. In the past 50 years, the amount of water withdrawn for human use has tripled. MAR is becoming an increasingly important method for improving and supplementing subsurface freshwater storage and ecosystems with an additional benefit of reducing flood risk, managing stormwater, mitigating subsidence, and controlling saltwater intrusion.

    Training Objectives

    • Understand MAR and its applications.
    • Recognize MAR as a process rather than a single technology.
    • Acknowledge that MAR can be widely applied.
    • Understand MAR's role in the future for addressing water supply resilience and climate impacts.

    Training Goals

    • Provide a model of the MAR process illustrating the primary components and their interaction.
    • Provide an overview of the applications of MAR and the role in addressing climate change impacts through sustainability and resilience in water resources management.
    • Provide information on each component of MAR and the critical considerations for each component in the design of a MAR project.
    • Reference case studies illustrating the various applications of MAR.

    After the MAR Training, the audience will have the tools necessary to understand MAR and how it can be used as a water resource management tool that encompasses a wide variety of water sources, recharge methods, and storage management practices. The audience will develop an understanding of MAR and its importance in achieving sustainability, resilience, and the far-reaching benefits of MAR related to water supply and quality, mitigation of saltwater intrusion, flood control, and ecological habitats. This training will provide information about the components of a MAR project to help regulators, practitioners, and stakeholders in the development and review of a MAR project.

  • ITRC: Contaminants of Emerging Concern (CEC) Identification FrameworkInterstate Technology and Regulatory Council
    October 22, 2024, 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: MicroplasticsInterstate Technology and Regulatory Council
    November 7, 2024, 1:00PM-3:00PM EST, 18:00-20:00 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 (available in February 2023) 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.

  • Sediment Cap Chemical Isolation TrainingInterstate Technology and Regulatory Council
    November 21, 2024, 1:00PM-3:00PM EST, 18:00-20:00 GMT
    In 2023, ITRC published the Sediment Cap Chemical Isolation Guidance to supplement the 2014 Contaminated Sediments Remediation Guidance with the goal of improving consistency in sediment cap performance outcomes. Sediment capping is a commonly selected remediation approach and numerous designs have been completed. Previous cap designs have been evaluated in multiple ways, and these varying approaches have led to some differences in selection of chemical design criteria, construction tolerance specifications, and monitoring/maintenance objectives for sites with similar characteristics and contaminants, leading to different expectations for long-term performance and reliability.

    The ITRC Sediment Cap Chemical Isolation Guidance provides a framework for the design, construction, and long-term monitoring of the chemical isolation function of sediment caps. The framework consists of an iterative design process informed by site-specific data that balances achievement of chemical design criteria, physical design constraints, constructability and permitting requirements. In addition, the guidance summarizes key construction considerations and presents a recommended approach for monitoring and evaluating long-term chemical isolation performance. The recommended framework presented in the Sediment Cap Chemical Isolation Guidance is illustrated below.




    The Sediment Cap Chemical Isolation Training will cover several key elements of the recommended framework, including:
    • A capping overview that summarizes objectives of capping, role of the chemical isolation layer, and generic cap types and compositions.
    • A discussion of performance objectives and design concepts that includes the selection of chemical isolation performance targets criteria and development of design criteria while considering the site setting and conceptual site model elements.
    • An overview of chemical isolation layer modeling tools and discussion of their applicability to support chemical isolation design, important model input parameters, and the impact of uncertainty and sensitivity of modeling results.
    • A summary of chemical isolation construction considerations, including an overview of available construction methods and tolerances and quality assurance and quality control measures.
    • A discussion of cap performance monitoring and maintenance objectives and approaches that include developing monitoring objectives to assess chemical isolation performance and methods for guiding long-term maintenance decisions.

    We encourage participants to review the ITRC Sediment Cap Chemical Isolation Guidance (SD-1) before and after the training to become familiar with the topics and recommendations discussed during the training. This training is intended for all environmental professionals working in the field of sediment capping projects, including regulators and other government agency staff, consultants, project stakeholders, and industry.
