ITRC: Overview of the Tire-Derived Chemicals 6PPD & 6PPD-quinone Training - Thursday, May 1, 2025, 1:00PM-2:30PM EDT (17:00-18:30 GMT). This course provides 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.

FRTR Spring 2025 General Meeting (Sessions 1 and 2) - Tuesday, May 13, 2025, 1:00PM-5:00PM EDT (17:00-21:00 GMT) and Wednesday, May 14, 2025, 1:00PM-5:00PM EDT (17:00-21:00 GMT). The Spring 2025 General Meeting of the FRTR focuses on innovative approaches to characterize and survey complex mixtures of legacy and emerging contaminants in surface and subsurface environmental media. These include characterization of PFAS mixed with legacy contaminants, and the survey of organo-metallic and radiological contaminants to advance industrial application, enhance efficiency and reduce cost of remediation. For more information and to register, see https://www.clu-in.org/live. ITRC: Contaminants of Emerging Concern (CEC) Identification Framework Training - Thursday, May 15, 2025, 1:00PM-3:00PM EST (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 training presents this entirely new framework for identification, prioritization, and communication of CEC. Participants will learn the elements of the CEC framework and gain an understanding of the framework application from case studies. For more information and to register, see https://www.itrcweb.org or https://www.clu-in.org/live. ITRC: PFAS Beyond the Basics: Topics on PFAS Biosolids: Sources, Transport, and Management of PFAS Surface Releases Training - Tuesday, May 20, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This training class builds on the earlier information for introductory PFAS topics presented in the PFAS 101 CLU-IN training. The ITRC PFAS Beyond the Basics class provides more information related to potential sources of PFAS in biosolids, implications of PFAS associated with land-applied biosolids, vadose zone fate and transport processes that likely govern biosolids releases, treatment/disposal options for PFAS-impacted biosolids, and regulatory considerations. For more information and to register, see https://www.itrcweb.org or https://www.clu-in.org/live. ITRC: Reuse of Solid Mining Waste Training - Thursday, May 29, 2025, 1:00PM-3:00PM EST (17:00-19:00 GMT). Solid mining waste represents a significant quantity of waste material in the United States and around the world. Solid mining waste has a range of physical and chemical properties that make it both potentially valuable and potentially hazardous to human health and the environment. From a commercial perspective, mining removes most of the primary minerals of interest; however, waste materials can still contain valuable minerals and other materials that can be recovered. The ITRC Reuse of Solid Mining Waste training and guidance document is geared towards state regulators and environmental consultants, mining and manufacturing stakeholders, community and tribal stakeholders, and other who have an interest in the potential reuse of solid mining waste. For more information and to register, see https://www.itrcweb.org or https://www.clu-in.org/live. ITRC: PFAS Beyond the Basics: PFAS Treatment Technologies Training - Tuesday, June 3, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This training class builds on the earlier information for treatment technologies presented in the PFAS 101 CLU-IN training. It provides more in-depth information regarding considerations for implementing integrated PFAS treatment technologies and remediation strategies. This training introduces the concept that achieving site remedial objectives will likely necessitate the implementation of multiple treatment technologies and remediation strategies (i.e., an integrated remedial strategy). Specifically, this training uses a hypothetical conceptual site model to frame the discussion of remedial approaches for PFAS impacted source area soil, source area groundwater, and more dilute groundwater plumes. The training concludes with a discussion of select field implemented and developing disposal and destructive technologies for managing treatment residuals.

RemPlex: Subsurface Sensing: Advancing Electrical Geophysical Techniques for Non-Invasive Characterization and Monitoring at Complex Sites - Tuesday June 3, 2025, 11:00AM-12:30PM EDT (15:00-17:30 GMT). Explore the application of geophysical techniques for understanding, characterizing and monitoring complex remediation sites, with a special focus on the Spectral Induced Polarization (SIP) method. SIP is an exciting emerging geophysical technology that can offer unique non-invasive information on both the physical and geochemical conditions of the subsurface-particularly in environments where contamination and heterogeneous geological conditions pose significant challenges to collecting data at relevant spatial and temporal scales. The seminar will highlight recent advancements in both lab-scale analysis of SIP signals and their field-scale applications. Presented by the Center for the Remediation of Complex Sites (RemPlex).

DoD Environmental Data Quality Workgroup (EDQW) Memorandum on Issues with Applying the Incremental Sampling Methodology (ISM) to PFAS Investigations (January 2025). ISM is a sampling protocol that involves collecting and combining a large number of soil sample increments of equal depth and mass across an area defined as a decision unit (DU). The ISM protocol is designed so a single composite sample result represents the mean concentration of a chemical constituent in the DU. After further review and consideration, the DoD EDQW has recommended to avoid the use of ISM for PFAS sampling and analysis.
