The U.S. Environmental Protection Agency (EPA) Superfund program has developed regulations and guidance for remediating radioactively contaminated CERCLA sites. The focus of this presentation is an overview of EPA's recommended guidance documents on ARARs and risk assessment, models for conducting risk and dose assessments, and community involvement tools for engaging in meaningful involvement with the public that are intended to be used during the process to determine cleanup levels for radioactively contaminated Superfund sites. The presentation is intended to help the audience obtain knowledge of EPA's recommended guidance to facilitate cleanups that are consistent with how chemical contaminants are addressed, except where technical differences posed by radiation are addressed. The guidance and tools that are discussed in the presentation are freely available on the internet. This webinar provides an updated version of Module 3 that was presented in the ITRC webinar "Radiation Site Cleanup: CERCLA Requirements and Guidance" on June 5, 2007.

The ITRC Environmental Data Management Best Practices Team (EDMBP Team) prepared a series of guidance documents and case studies on best practices for all phases of EDM to address the need for guidance on managing large stores of environmental data. Environmental data management (EDM) is a broad field that encompasses all aspects of environmental research and regulation, from habitat studies and wildlife management plans to health advisories and remediation of hazardous waste sites.

The EDMBP Team developed three Roundtable training sessions to support the Guidance Document and case studies. You are welcome to register for any of the three, but they do not build upon each other.Data Management: Real Life Application of Data Management Planning and Field Data Collection Best PracticesData Exchange: Best Practices for Exchanging Environmental DataData Quality: Best Practices for Achieving and Maintaining Quality within Environmental Data ManagementWhat good are data if you can't access it? At its root, data exchange is about making data accessible. It is the process of sharing data between systems. When it's done best, it is efficient, repeatable, and maintains the integrity of the data. At its worst, data are omitted, are mismatched, or there is no documentation on its origin. We think of data exchange in terms of incoming data and outgoing data. With incoming data, best practices span from inventorying sources to loading the data into a system. With outgoing data, best practices focus on documentation and automating exports into known schemas.

During this Roundtable training, we will tackle some of the challenging issues in data exchange. If you're new to data exchange, it may open your eyes. If you've been exchanging data for years, we hope to provide some new tricks or considerations for you. Some of the topics we'll cover include:What's the best way to handle using several analytical laboratories, each with a different electronic data deliverable (EDD)? When systems use different valid values and schema, how can you design an efficient, repeatable exchange? How do we know that the costly effort to extract, transform, and load the data from old PDFs into our system will provide value? If someone asks for "all the data" but doesn't have a plan for import to an existing system, how do you provide it in an understandable way in a raw format?We want to answer your questions too. Are you wondering about how to handle analytes duplicated with multiple analytical methods? Or when you should automate or when to manually exchange? No question is too minor.

The Technical Review Workgroup (TRW) Bioavailability Committee recently published the "Guidance for Sample Collection for In Vitro Bioaccessibility Assay for Arsenic and Lead in Soil and Applications of Relative Bioavailability Data in Human Health Risk Assessment." This is an update to the 2015 Guidance for Sample Collection for In Vitro Bioaccessibility Assay for Lead (Pb) in Soil. The update is intended to help EPA risk assessors, remedial project managers, and on-scene coordinators develop and use bioavailability data at their sites. It incorporates sample planning and data analysis recommendations from EPA's Guidance on Systematic Planning Using the Data Quality Objectives Process that are pertinent to sampling for In Vitro Bioaccessibility (IVBA) and Relative Bioavailability (RBA). It also clarifies the application of IVBA and RBA data to human health risk assessment, the development of risk-based goals at CERCLA remedial and removal sites and includes arsenic (As) which was recently added to the In Vitro Bioaccessibility Assay.

The TRW has developed a series of trainings based on the updated guidance. This session will focus on a discussion of soil sample collection and processing best practices and methods to directly measure relative bioavailability (RBA) or estimate RBA by measuring in vitro bioaccessibility via EPA Method 1340 at soil arsenic and lead contaminated sites.  This training will target a general audience of regional staff working in risk assessment, remediation, emergency response, technical support, and quality assurance. The training will be an approximately one hour long and will include time for general discussion. Members of the Bioavailability Committee and a Regional representative will be present to answer questions in real time.

ITRC's Vapor Intrusion Mitigation training is a series of eight (8) modules, presented over two sessions.

The Vapor Intrusion Mitigation training series provides an overview of vapor intrusion mitigation and presenting information from the ITRC fact sheets, technology information sheets, and checklists (VIM-1, 2021):
Session 1:Introduction & Overview of Vapor Intrusion Mitigation Training TeamConceptual Site Models for Vapor Intrusion MitigationPublic Outreach During Vapor Intrusion MitigationRapid Response & Ventilation for Vapor Intrusion MitigationRemediation & Institutional Controls
Session 2:Active Mitigation ApproachesPassive Mitigation ApproachesSystem Verification, OM&M, and Exit Strategies

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.

After the Vapor Intrusion Mitigation series, you should understand:How to locate and utilize the VIM-1 fact sheets, technology information sheets, and checklistsThe importance of a VI mitigation conceptual site modelHow public outreach for VI mitigation differs from other environmental mattersWhen to implement rapid response for vapor intrusion and applicable methodologies The differences between remediation, mitigation, and institutional controlsAvailable technologies for active and passive mitigation, and design considerations for various approachesHow/when/why different mitigation technologies are appropriateHow to verify mitigation system success, address underperformance, and develop a plan for discontinuing a mitigation system
We encourage you to use the ITRC Vapor Intrusion Mitigation work products (VIM-1) and these training modules to learn about vapor intrusion mitigation and how you can apply these best practices to improve decision-making at your sites. For regulators and other government agency staff, this understanding of vapor intrusion mitigation can be incorporated into your own programs.

While the training makes every effort to keep the information accessible to a wide audience, it is assumed that the participants will have some basic technical understanding of chemistry, environmental sciences, and risk assessment. As with other emerging contaminants, our understanding of vapor intrusion mitigation continues to advance. This training provides the participants with information on areas where the science is evolving and where uncertainty persists.
