The instructional methodology for this course includes lecture, group discussion, and quizzes. The target audience for this course is federal, state, and tribal representatives who work on Federal Facility cleanups. Ideally, students should have a basic understanding of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) process. This course is part of the Federal Facilities Academy training program. For more information and to register, please visit https://clu-in.org/live/. ITRC Strategies for Preventing and Managing Harmful Cyanobacteria Blooms (Two Part Series) - October 13 and November 8, 2022. Cyanobacteria are microscopic, photosynthetic organisms that occur naturally in all aquatic systems but most often in freshwater systems. Under certain conditions, cyanobacteria can multiply and become very abundant, discoloring the water throughout a water body or accumulating at the surface. These occurrences are known as blooms. Cyanobacteria may produce potent toxins (cyanotoxins) that pose a threat to human health. They can also harm wildlife and domestic animals, aquatic ecosystems, and local economies by disrupting drinking water systems and source waters, recreational uses, commercial and recreational fishing, and property values. It is likely that continued population growth, land use change, increases in nutrient inputs to our waterways, and the warming climate will favor proliferation of these problematic species. Providing a range of practical approaches to minimize these blooms and their likely societal and wildlife effects is critical to our future vitality, health, and economic prosperity.

ITRC 1,4-Dioxane: Science, Characterization & Analysis, and Remediation - October 18, 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.

Volatile organic compound (VOC) contamination in the vadose zone presents a potential threat to underlaying groundwater and/or to nearby structures through vapor intrusion. Such contamination is often addressed using soil vapor extraction (SVE), in which a vacuum is applied to the unsaturated zone to remove VOCs from the soil gas through a physical, mass transfer and extraction process. Typical of such processes, SVE can exhibit a diminishing rate of contaminant extraction over time. Current SVE performance assessment guidance provides a structured approach for assessing remediation of volatile contaminant sources in the vadose zone to determine whether the remedy should be terminated, optimized, supplemented, or transitioned to another technology. Quantification of the impacts of the remaining vadose zone source on groundwater and soil gas concentrations is a key element of this performance assessment. This seminar will discuss the U.S. Department of Energy's SVE performance assessment guidance and the associated Soil Vapor Extraction Endstate Tool (SVEET) software, that has recently been updated as part of an Environmental Security Technology Certification Program (ESTCP) project. Application of the guidance and tool will be illustrated using information from the ESTCP demonstration and from an evaluation of a SVE system at the DOE Hanford Site. Collectively, SVE performance assessments provide a defensible technical basis for making decisions about vadose zone remediation to provide a path that protects human health and the environment while making effective use of limited resources.

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 or https://clu-in.org/live. NIEHS Climate Change and Health: Session II - Untangling Complex Exposures and Health Effects - November 4, 2022, 1:00PM-3:00PM EDT (17:00-19:00 GMT). The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on scientific research and tools that can be used to promote health and resilience to climate change. The series will feature SRP-funded researchers, collaborators, and other subject-matter experts who aim to better understand and address how climate change affects human exposures to hazardous substances and the public health consequences of a changing climate and identify ways to build health resilience. People are continually exposed to a complex mixture of environmental toxicants. The second session will describe how extreme weather events, such as hurricanes and wildfires, and other extreme events affect the distribution of these pollutants, their toxicity, and the potential increased risk of exposure to humans. Presenters will introduce new models to track the movement of multiple contaminants in the environment and will discuss the health effects of these complex exposures. We will also hear about the NIH Climate Change and Health Initiative and other ongoing efforts at NIH to reduce the health consequences associated with climate change. This is the second session in a three part series. For more information and to register, please visit https://clu-in.org/live/. Research Brief 333: Combining Arsenic Data Across Populations Sheds Light on Exposure Sources. By combining data across three different populations, NIEHS Superfund Research Program (SRP) researchers were able to better characterize sources of arsenic exposure that should be included in risk assessments. The study was a collaboration among the University of California (UC), Berkeley, University of New Mexico (UNM), and Columbia University SRP centers. Arsenic, naturally found in earth's crust, is associated with a range of health problems including diabetes, cardiovascular disease, and cancer. Health risk estimates are primarily based on exposure to arsenic in drinking water. Arsenic is mostly excreted from the body through urine. But the researchers found that comparisons of levels of arsenic that people ingest to levels of arsenic that they excrete were inconsistent. They believed that revealing other exposure sources in water, food, and dust might be important, especially for specific populations.
