ITRC: Pump & Treat Optimization Training - May 5, 2026, 1:00PM-3:00PM EDT (17:00-19:00 UTC). This 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. 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.

ITRC: Contaminants of Emerging Concern (CEC) Identification Framework Training - May 7, 2026, 1:00PM-3:00PM EDT (17:00-19:00 UTC). 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. 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. This ITRC CEC training presents this entirely new framework for identification, prioritization, and communication of CEC.

ITRC: Understanding Vapor Intrusion - Introductory Concepts & Fundamentals - A Two Part Series, Session 2 - May 12, 2026, 1:00PM-3:00PM EDT (17:00-19:00 UTC). This is the second of a two-part series. 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: Introduction to Hydrocarbons Training - May 19, 2026, 1:00PM-3:00PM EDT (17:00-19:00 UTC). 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. For more information and to register, see https://www.itrcweb.org or https://www.clu-in.org/live.
