Upcoming Live Internet Seminars
ITRC Integrated DNAPL Site Characterization – May 5, 2022, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The
Integrated DNAPL Site Characterization Team has synthesized the knowledge about dense nonaqueous phase liquid (DNAPL) site characterization and remediation
acquired over the past several decades, and has integrated that information into a new document, Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015). This guidance is a resource to inform regulators, responsible parties, other problem holders, consultants, community stakeholders, and other interested parties of the critical concepts related to characterization approaches and tools for collecting subsurface data at DNAPL sites. After this associated training, participants will be able to use the guidance to develop and support an integrated approach to DNAPL site characterization, including: identify what site conditions must be considered when developing an informative DNAPL conceptual site model (CSM); define an objectives-based DNAPL characterization strategy; understand what tools and resources are available to improve the identification, collection, and evaluation of appropriate site characterization data; and navigate the DNAPL characterization tools table and select appropriate technologies to fill site-specific data gaps.

ITRC Long-term Contaminant Management Using Institutional Controls – May 10, 2022, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Institutional controls (ICs) are administrative or legal restrictions that provide protection from exposure to contaminants on a site.
When ICs are jeopardized or fail, direct exposure to human health and the environment can occur. While a variety of guidance and research to date has focused on the implementation of ICs, ITRC’s Long-term Contaminant Management Using Institutional Controls (IC-1, 2016) guidance and this associated training class focuses on post-implementation IC management, including monitoring, evaluation, stakeholder communications, enforcement, and termination. The ITRC guidance and training will assist those who are responsible for the management and stewardship of ICs. After attending the training, participants will be able to: describe best practices and evolving trends for IC anagement at individual sites and across state agency programs; use this guidance to improve IC reliability and prevent IC failures, improve existing, or develop new, IC Management programs, identify the pros and cons about differing IC management approaches; use the tools to establish an LTS plan for specific sites; and use the elements in the tools to understand the information that should populate an IC registry or data management system.

ITRC Connecting the Science to Managing LNAPL Sites a 3 Part Series: Part 1 – May 12 and June 7 & 14, 2022. The newly updated LNAPLs (Light Non-Aqueous Phase Liquids) 3-part training course series is based on the ITRC guidance: LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018) and focuses on connecting the science to managing LNAPL sites and helping you: build upon your understanding of LNAPL behavior in the subsurface (Part 1), develop your LNAPL conceptual site model and LNAPL remedial goals (Part 2), and select/implement LNAPL technologies (Part 3). After this training series, the expectation is that you will have the skills and understanding to use ITRC science-based resources to improve decision making at your LNAPL sites. For regulators and other government agency staff, this improved understanding can hopefully be incorporated into your own LNAPL programs. It is expected that participants will attend this 3-part training series in sequence. For more information

Utilizing Innovative Materials Science Approaches to Enhance Bioremediation: Session III – Plant and Fungal-based Bioremediation – May 13, 2022, 1:00PM-3:00PM EDT (17:00-19:00 GMT). The NIEHS Superfund Research Program (SRP) is hosting a Progress in
Research webinar series to showcase new breakthroughs to advance sustainable solutions for hazardous substances in the environment. The three-part series will feature SRP individual research projects funded in 2020, who are incorporating new advances in materials science to optimize bioremediation of contaminants in soil, sediment, or water. In each session, awardees will describe their research
projects, accomplishments, and next steps. The third and final session will focus on strategies to improve how plant and
fungi remove hazardous substances from soil. For more information and to register, please visit https://clu-in.org/live.
ITRC 1,4-Dioxane: Science, Characterization & Analysis, and Remediation – May 17, 2022, 1:00PM-3:15PM EDT (17:00-19:15 GMT). 1,4-Dioxane has seen widespread use as a solvent stabilizer since the 1950s. The widespread use of solvents through the 1980s suggests its presence at thousands of solvent sites in the US; however, it is not always a standard compound in typical analytical suites for hazardous waste sites, so it previously was overlooked. The U.S. EPA has classified 1,4-dioxane as “likely to be carcinogenic to humans.” Some states have devised health standards or regulatory guidelines for drinking water and groundwater standards; these are often sub-part per billion values. These low standards present challenges for analysis, characterization, and remediation of 1,4-dioxane. The ITRC team created multiple tools and documents that provide information to assist all interested stakeholders in understanding this contaminate and for making informed, educated decisions.

ITRC Vapor Intrusion Mitigation (VIM-1) – A Two Part Series – June 2 and 14, 2022, 1:00PM-3:00PM EDT (18:00-20:00 GMT). When certain contaminants or hazardous substances are released into the soil or groundwater, they may volatilize into soil gas. Vapor intrusion (VI) occurs when these vapors migrate up into overlying buildings and contaminate indoor air. ITRC has previously released guidance documents focused on VI, including the “Vapor Intrusion Pathway: A Practical Guidance” (VI-1, 2007) and “Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management” (PVI, 2014). However, ITRC has received multiple requests for additional details and training on mitigation strategies for
addressing this exposure pathway. The ITRC Vapor Intrusion Mitigation Team (VIMT) created ten fact sheets, 16 Technology information sheets, and 4 checklists with the goal of assisting regulators during review of vapor intrusion mitigation systems, and helping contractors understand the essential elements of planning, design, implementation, and operation, maintenance and monitoring (OM&M) of mitigation systems. The Vapor Intrusion Mitigation
training is a series of eight (8) modules, presented over two sessions. For more information and to register, see https://www.itrcweb.org

Research Brief 328: Sampling Device May Predict Methylmercury Accumulation in Wetlands. NIEHS
Superfund Research Program (SRP)-funded researchers, led by Heileen Hsu-Kim, Ph.D., of the Duke University SRP Center, showed that a small plastic sampling device can efficiently predict the potential for methylmercury — an environmental contaminant — to form in freshwater wetlands and to accumulate in organisms living there. In aquatic ecosystems, inorganic mercury changes to methylmercury through microbial activity. Inorganic mercury occurs naturally in the environment but can also be found in some consumer products, as well as in emissions from coal-fired power plants and other industrial activities. The contaminant can build up in animal tissues, with toxic effects to the nervous system. Because methylmercury occurs in greater amounts up the food chain, humans who eat large fish can also be exposed. To view the brief, please visit https://tools.niehs.nih.
