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 b...

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...

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....

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 co...

This training will provide information on fate and transport of PFAS in the environment using a hypothetical AFFF release. It builds on the earlier topics covered in the PFAS 101 training. Resources and further details for the topics included in this training are available in the ITRC PFAS-1 guidance document. Representative PFAS fate and transport pathways/processes will be illustrated, highlight...

RODs [Records of Decision] and More at Federal Facilities is a two-hour webinar course that will provide an overview of how early and interim actions, adaptive management, RODs, Explanations of Significant Differences (ESDs), ROD Amendments, removal actions and Five-Year Reviews are used at Federal Facilities. By taking this course, participants will achieve the following objectives:Understand how...

ITRC's Vapor Intrusion Mitigation training is a series of eight (8) modules, presented over two sessions. If you took the ITRC VIM series previously, the content has stayed the same, but the new course directs people to the Vapor Intrusion (VI) Toolkit resources published in January 2026 by ITRC. The Vapor Intrusion Mitigation training series provides an overview of VIM and presents information fr...

This ITRC training will provide information on the current understanding of PFAS and biosolids, focusing on land application. It builds on the earlier topics covered in the PFAS 101 training.
