Tips and Tricks to Improve Groundwater Remedy Selection and Performance - Wednesday, April 2, 2025, 1:00PM-2:30PM EDT (17:00-18:30 GMT). Performance data for treatment technologies such as permeable reactive barriers, chemical oxidation, and chemical or biological reductive dechlorination suggests there are factors that may consistently impact the effectiveness of groundwater remediation at sites with volatile organic contamination. Aquifer and remedy geochemistry, site characterization, and implementation issues are factors that have impacted groundwater remedy performance at a number of sites. After illustrating these performance factors through case studies, we will cover tips and tricks that can be used to increase the likelihood of a successful groundwater remedy.

Framework for Investigating Asbestos-Contaminated CERCLA Sites (Parts 1 and 2) - Tuesday, April 15, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT) and Wednesday, April 16, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This virtual training will discuss the updated Framework for Investigating Asbestos-Contamination at Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Sites (released in 2021). By taking this training, participants will learn how to better assess exposure and risk from asbestos and consider unique scientific and technical issues associated with the investigation of human exposure and risk from asbestos. The training modules will discuss specific strategies that are based on the best currently available science as well as methods for characterizing exposure and risk from asbestos to inform risk-management.

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. ITRC Sediment Cap Chemical Isolation Training - Tuesday, April 22, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT). In 2023, ITRC published the Sediment Cap Chemical Isolation Guidance to supplement the 2014 Contaminated Sediments Remediation Guidance with the goal of improving consistency in sediment cap performance outcomes. Sediment capping is a commonly selected remediation approach and numerous designs have been completed. Previous cap designs have been evaluated in multiple ways, and these varying approaches have led to some differences in selection of chemical design criteria, construction tolerance specifications, and monitoring/maintenance objectives for sites with similar characteristics and contaminants, leading to different expectations for long-term performance and reliability. The Sediment Cap Chemical Isolation Training will cover several key elements of the recommended framework.

Economic Prosperity and Community Growth Through Superfund Redevelopment - Wednesday, April 23, 2025, 1:00PM-2:00PM EDT (17:00-18:00 GMT). The EPA Superfund Redevelopment Program's mission is to protect human health and the environment and promote the reuse of Superfund sites. Restoring these once-contaminated properties to productive use revitalizes local economies and prioritizes economic prosperity, spurring new jobs, business growth, tax revenues, spending and new amenities for communities. This webinar showcases the economic benefits of Superfund Redevelopment for communities across the country. Participants will hear about the most up-to-date economic numbers and success stories. They will also learn about tools used at Superfund sites to ensure that reuse projects meet local needs and reflect community priorities, as part of restoring the greatness of the American economy.

ITRC PFAS Beyond the Basics: PFAS Fate and Transport, Site Characterization and Source ID Training - Thursday, April 24, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This training class builds on the earlier information for fate and transport and site characterization presented in the PFAS 101 CLU-IN training. It provides more in-depth information for fate and transport, site characterization, source identification and some introductory information on environmental forensics. These topics will be presented along with options and a framework for data visualization. This training will focus largely on PFAS fate and transport in groundwater. The goal is to provide detailed information about the inputs practitioners can use to develop a robust conceptual site model to help understand fate and transport at PFAS sites, and how to gather evidence of multiple sources.

Military Munitions Support Services (M2S2) - Sessions from the STAND DOWN - Remedial Actions - Tuesday, April 29, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT). M2S2 will be presenting three webinars in FY25, titled "Sessions from the STAND DOWN" highlighting presentations from the FY25 M2S2 Stand Down hosted by US Army Corps of Engineers (USACE) in December 2024. These online events will bring together USACE, DoD leaders, federal land managers, state and federal regulators and contractors to discuss munitions response cleanup issues and initiatives. Presenters and attendees will discuss programmatic information, and share lessons learned to foster strong working relationships. The first webinar in this series will focus on Remedial Actions.

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). 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. This ITRC training 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.
