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 Vapor Intrusion Mitigation (VIM-1) - A Two Part Series, June 1 and 6, 2023. 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. ITRC 1,4-Dioxane: Science, Characterization & Analysis, and Remediation June 8, 2023, 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. This 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.

In response to one of the biggest emerging environmental concerns, ITRC formed the Microplastics Team in 2021 to develop the Microplastics Guidance Document. Plastics have become pervasive in modern life and are now used in a wide range of commercial and industrial applications. Microplastics may result from the degradation and fragmentation of larger plastics, or they may be intentionally produced for specific applications and products. Regardless of their origin, microplastics are now ubiquitous in our environment. Because of their small size and pervasiveness in the environment, microplastics, along with any other contaminants which are adhered to the microplastics, may be inadvertently consumed by humans and other organisms.

USACE The Best of the SAGEEP/MRM: Lessons Learned, Case Studies, and Emerging Technologies in support of MMRP, June 28, 2023, 1:00PM-4:00PM EDT (17:00-20:00 GMT). The M2S2 webinars have proven to be valuable forums to share information across our munitions response industry, on a wide range of topics and presented by a variety of subject matter experts representing multiple perspectives. In April 2023, the Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP), in conjunction with the National Association of Contractors and the 2nd Munitions Response Meeting, held 3 days of technical talks focused on lessons learned, case studies, and emerging technologies in support of MMRP. The talks that best fit a wider audience of project managers and stakeholders were selected to be presented during this M2S2 webinar. Talks will focus on Advanced Geophysical Classification (AGC), underwater research and development, alternative positioning systems, recent lessons learned, and novel applications of technology.

EPA recently released a climate adaptation profile describing measures taken at the Rocky Mountain Arsenal in Commerce City, Colorado. Ongoing remediation work at this National Priorities List site includes maintaining two landfill caps and six evapotranspiration covers and operating five groundwater extraction and treatment systems. The site is vulnerable to drought conditions, erosion and sheet flow associated with intense or prolonged precipitation, and potential wildfires. Design and construction of the cover and capping systems included multiple measures to address the vulnerabilities, such as armoring associated drainage channels with concrete block, using drought-tolerant species to vegetate top surfaces, and periodically conducting prescribed burns of the vegetation to reduce fuel for wildfires. Other measures to enhance climate resilience of the site's infrastructure include storing site-wide stormwater in three onsite lakes and beneficially using the site's treated groundwater to recharge the local aquifer. Approximately 15,000 of the site's 17,000 acres have been incorporated into the Rocky Mountain Arsenal National Wildlife Refuge.

Research Brief 341: Fighting Fluorine with Fluorine: New Materials Remove PFAS from Groundwater. Researchers funded by the NIEHS Superfund Research Program (SRP) created a novel class of materials that can attract and remove per- and polyfluoroalkyl substances (PFAS) from water. According to the authors, the new technology - called Fluor Mop - can be regenerated, reused, and is potentially less expensive than current remediation strategies. For more information and to read the brief, please visit https://tools.niehs.nih.gov/srp/researchbriefs/view.cfm?Brief_ID=341 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.
