Welcome to TechDirect! Since the January 1 message, TechDirect gained 96 new subscribers for a total of 44,120. If you feel the service is valuable, please share TechDirect with your colleagues. Anyone interested in subscribing may do so on CLU-IN at https://clu-in.org/techdirect . All previous issues of TechDirect are archived there. The TechDirect messages of the past can be searched by keyword or can be viewed as individual issues. TechDirect's purpose is to identify new technical, policy and guidance resources related to the assessment and remediation of contaminated soil, sediments and groundwater. Mention of non-EPA documents or presentations does not constitute a U.S. EPA endorsement of their contents, only an acknowledgment that they exist and may be relevant to the TechDirect audience. ITRC: 1,4-Dioxane: Science, Characterization & Analysis, and Remediation Training - Thursday, February 6, 2025, 1:00PM-3:15PM EST (18:00-20:15 GMT). In 2020, ITRC's 1,4-Dioxane team created multiple tools and documents that provide information to assist all interested stakeholders in understanding this contaminant and for making informed, educated decisions. Since the 1950s, 1,4-Dioxane has seen widespread use as a solvent stabilizer. The 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 1,4-Dioxane: Science, Characterization & Analysis, and Remediation training is a series of six (6) modules. The six individual modules will be presented together live, and then archived on the ITRC 1,4-Dioxane training webpage for on demand listening.

Solid mining waste represents a significant quantity of waste material in the United States and around the world. Solid mining waste has a range of physical and chemical properties that make it both potentially valuable and potentially hazardous to human health and the environment. From a commercial perspective, mining removes most of the primary minerals of interest; however, waste materials can still contain valuable minerals and other materials that can be recovered. The different types of mining sites and potential wastes for reuse provide a significant challenge but also an opportunity for innovation. The ITRC Reuse of Solid Mining Waste training and guidance document (document available January 2025) is geared towards state regulators and environmental consultants, mining and manufacturing stakeholders, community and tribal stakeholders, and other who have in interest in the potential reuse of solid mining waste.

ITRC: PFAS Beyond the Basics: Sampling, Analysis, Surface Water, & Air Occurrence Training - Tuesday, February 25, 2025, 1:00PM-3:00PM EST (18:00-20:00 GMT). This ITRC training course will build upon PFAS sampling and analysis information presented in the PFAS 101 CLU-IN training. The ITRC PFAS Beyond the Basics class provides in-depth information on preparing for and implementing sampling events. Some detailed information and case studies are presented for sampling surface water and PFAS-containing foam that can form and aggregate at the surface water-air interface. The training includes information about PFAS analysis and discusses alternative qualitative analytical techniques. The occurrence of PFAS in air information from the literature for outdoor air, indoor air, settled dust and precipitation is discussed. For more information and to register, see https://www.itrcweb.org or https://www.clu-in.org/live. ITRC: Vapor Intrusion Mitigation (VIM-1) - A Two Part Series Training - Thursday, February 27, 2025, 1:00PM-3:00PM EST (18:00-20:00 GMT) and Tuesday, March 11, 2025, 1:00PM-3:00PM EDT (17:00-19:00 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.

The Department of Defense's Environmental Security Technology Certification Program (ESTCP) released a solicitation on January 7, 2025, requesting proposals for demonstrations of environmental and installation energy technologies. The due date for all pre-proposals is due March 6, 2025. For more information, please visit https://serdp-estcp.mil/workwithus . Technology Innovation News Survey Corner. The Technology Innovation News Survey contains market/commercialization information; reports on demonstrations, feasibility studies and research; and other news relevant to the hazardous waste community interested in technology development. Recent issues, complete archives, and subscription information is available at https://clu-in.org/products/tins/. The following resources were included in recent issues:
EPA Superfund Site Remediation Program: Radiation Risk Assessment Calculator Training - Phoenix, AZ, March 9, 2025. The US EPA Superfund Radiation Risk Assessment is a full-day advanced course will be delivered at the upcoming 2025 Waste Management Symposia. This course focuses on specific technical and regulatory issues that site managers (e.g., RPMs, OSCs) and technical staff (e.g., risk assessors, health physicists) address when managing sites under the US Environmental Protection Agency's Superfund remedial program. This includes conducting a risk assessment for radioactive contaminants. Class instructors are Stuart Walker of U.S. EPA and Fred Dolislager of Oak Ridge National Laboratory.

The Symposium, hosted by the National Institutes of Health (NIH), will be both an in-person and virtual gathering of federal agencies to provide existing and relevant environmental information to Federal representatives. This event was first offered in 2002 and hosted at the NIH facility. The main purpose is to encourage partnerships, sharing of information, and best practices amongst Federal facilities. NIH will once again host the symposium virtually via MS Teams videoconferencing platform. This year's theme for the Symposium "Supporting the Mission Through Environmental Compliance" focuses on the sharing of best practices, success stories, partnerships, and challenges and achievements of the federal practitioner community as they apply to your Agency's mission. The symposium is also expected to bring together federal agencies and their partnering organizations to provide existing and relevant environmental policy perspectives.
