    Audio for "ITRC: Contaminants of Emerging Concern (CEC) Identification Framework," Jan 16, 2025

    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: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.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.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.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.

    Audio for "ITRC: Overview of the Tire-Derived Chemicals 6PPD & 6PPD-quinone," Jan 14, 2025

    In October 2024, ITRC released the 6PPD & 6PPD-quinone Guidance Document to provide environmental professionals and communities with information about the current science and regulatory framework of 6PPD and 6PPD-quinone (6PPD-q). 6PPD-q is a contaminant of emerging concern and is a transformation product of the tire anti-degradant (6PPD), an antiozonant used in tires. Join us for this ITRC training course to get a basic overview of the science and policy measures surrounding the Tire Anti-Degradants 6PPD and 6PPD-q. Attendees will gain insight into the current state of knowledge on topics such as: background and use of 6PPD in tires, toxicity in aquatic species and humans; occurrence, fate, and transport; measuring, mapping, and sampling; mitigation measures; and policy, regulations, and laws. Currently, 6PPD is used in all tires and can contaminate stormwater and surface water anywhere tires are used. 6PPD-q was identified as a chemical fatal to coho salmon in 2020. Since that time, it has been documented as acutely toxic to multiple trout species found throughout the United States. 6PPD and 6PPD-q have been found in waterways, aquatic organisms, soils, air, and humans. This training will introduce you to the ITRC 6PPD & 6PPD-quinone Guidance Document which provides more technical detail than can be covered in this training course To view this archive online or download the slides associated with this seminar, please visit http://www.clu-in.org/conf/itrc/6PPD-Q_011425/

    Audio for "Challenges Met: Case Studies of Thermal Remediation," Jan 8, 2025

    Thermal remediation technologies became commercially available in the early 2000s, and since then have been used successfully to remediate a wide variety of contaminated sites. This presentation will discuss several case studies of some of the more challenging Superfund sites that have been remediated with thermal technologies, and how challenges were overcome.

    Audio for "Thermal Remediation of NAPLs," Jan 7, 2025

    Thermal technologies are some of the only remedial technologies that can readily address NAPL contaminants. This presentation will describe the thermal technologies that are commonly used today, and the types of contaminants and hydrogeologic conditions for which they are applicable.

    Audio for "Characterization Approaches for Various Types of NAPLs," Dec 19, 2024

    With an understanding of the characteristics of NAPLs, how they flow in soils, and the capabilities of the tools available for remedial investigations, approaches can be developed for determining the extent of NAPLs in the subsurface and making estimations of the contaminant mass. This presentation will describe the Triad approach for characterizing NAPL sites to determine the contaminant distribution, and the geologic and hydrogeologic properties of the subsurface that are critical for determining a technically sound remedial approach.

    Audio for "NAPL Migration in the Subsurface," Dec 18, 2024

    A wide variety of organic wastes, commonly referred to as nonaqueous phase liquids (NAPLs), are contaminating soils and groundwater. The physical properties of these NAPLs, including their density, volatility, and viscosity determine how they flow through soils, and understanding their flow in soils is key to understanding how to characterize and remediate NAPL sites. This presentation will include the properties of common NAPLs and describe how they migrate in soils. Future presentations will discuss approaches to characterizing NAPL sites, and how NAPLs can be remediated using thermal remediation techniques.

    Audio for "ITRC: Introduction to Hydrocarbons," Dec 5, 2024

    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 hydrocarbonsPetroleum chemistryHow TPH, LNAPL, and PVI are relatedBuilding 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 hydrocarbonsDefining LNAPL risks based on acute, saturation, composition, or aesthetic concernsEmphasize the importance of biodegradation in risk management decision makingHow 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) To view this archive online or download the slides associated with this seminar, please visit http://www.clu-in.org/conf/itrc/Hydrocarbons_120524/
