Interstate Technology & Regulatory Council (ITRC) Accepting New Project Team Proposals. ITRC invites any agency, organization, company, or individual to submit a Project Team proposal that addresses an environmental challenge and helps ITRC achieve their mission of reducing barriers to the deployment of innovative environmental technologies. Proposals must be submitted by 5:00 PM ET on May 29, 2026, to be considered for a 2027 Project Team. For more information, see https://itrcweb.org/submit-proposals/

ITRC: PFAS Sorption Based Technologies for Separation & Concentration of PFAS from Water Training - April 7, 2026, 1:00PM-3:00PM EST (17:00-19:00 UTC). 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. This training will be crafted for an audience with some basic understanding of PFAS and that has likely already attended the PFAS 101 training and the ITRC PFAS Beyond the Basics: Fate and Transport, Site Characterization, and Source ID training.

Federal Facilities Academy: Community Involvement at Federal Facilities - April 22, 2026, 1:00PM-3:00PM EDT (17:00-19:00 UTC). Community Involvement at Federal Facilities is a two-hour webinar course that focuses on community involvement requirements, resources, and techniques available for Federal Facilities being cleaned up at National Priorities List (NPL) sites under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). By taking the course, participants will achieve the following objectives: Learn about community involvement requirements under CERCLA; Understand the roles of the lead federal agency and the Environmental Protection Agency (EPA) in public involvement at Federal Facilities; Discover resources and tools available for community involvement activities; Explore community involvement techniques and approaches that can be used at Superfund sites; and, Identify community involvement opportunities throughout the Superfund process at Federal Facilities.

ITRC: Understanding Vapor Intrusion - Introductory Concepts & Fundamentals - A Two Part Series Training - April 30 and May 12, 2026, 1:00PM-3:00PM EDT (17:00-19:00 UTC). The Vapor Intrusion 101 training series provides an overview of vapor intrusion (VI) and presents information from the 2026 ITRC VI Toolkit (which includes fact sheets, technology information sheets, and checklists). This course introduces participants to the fundamentals of vapor intrusion, the process by which vapor-forming chemicals in contaminated soil or groundwater volatilize and migrate into buildings. The course will discuss sources, pathways, and receptors. It will identify and assess VI risks in various settings (residential, commercial, industrial) and familiarize participants with regulatory frameworks and guidelines (e.g., USEPA, state-specific regulations). The participants will gain working knowledge of how to develop a Conceptual Site Model (CSM), design and implement sampling strategies, establish data quality objectives (DQOs), and conduct data and risk evaluations. It will provide an overview of mitigation strategies, including various closure strategies, land use covenants, and institutional controls.

ITRC: Pump & Treat Optimization Training, May 5, 2026 - 1:00PM-3:00PM EDT (17:00-19:00 UTC). 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 Pump & Treat Optimization Training will provide a roadmap for optimizing a P&T system and refining the remedial strategy or shifting toward another remedial approach.

NAVFAC Open Environmental Restoration Resources (OER2): Lessons Learned from In Situ Per- and Polyfluoroalkyl Substances (PFAS) Sequestration, May 6, 2026 - 3:00PM-4:15PM EDT (19:00-20:15 UTC). This webinar will provide an overview of in situ sequestration approaches for PFAS, including commonly used amendments and application methods. Drawing from case studies, the webinar will highlight key lessons learned from implementing a range of PFAS sequestration strategies. For more information on the OER2, see https://exwc.navfac.navy.mil/Products-and-Services/Environmental-Security/NAVFAC-Environmental-Restoration-and-BRAC/Training/OER2-Webinars/.

DOE’s Savannah River National Laboratory (SRNL) Using Innovative Artificial Intelligence and Machine Learning Applications. SRNL’s Environmental Management and Legacy Management directorate is employing AI to solve challenging environmental problems. This includes the AI Accelerated Strategies and Solutions in Environmental Technology, or AI-ASSET, initiative. AI-ASSET is based on an existing project known as the Advanced Long-Term Environmental Monitoring Systems, or ALTEMIS, which has been used to predict the behavior and movement of contaminated groundwater plumes. Sensors embedded around the plume use geochemical, hydrological and geophysical data to passively monitor and predict contaminant movement.
