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 Optimizing Injection Strategies and In situ Remediation Performance - February 7, 2023, 1:00PM-3:15PM EST (18:00-20:15 GMT). ITRC developed the guidance: Optimizing Injection Strategies and In Situ Remediation Performance (OIS-ISRP-1) and this associated training course to identify challenges that may impede or limit remedy effectiveness and discuss the potential optimization strategies, and specific actions that can be pursued, to improve the performance of in situ remediation by: refining and evaluating remedial design site characterization data; selecting the correct amendment; choosing delivery methods for site-specific conditions; creating design specifications; conducting performance evaluations, and optimizing under-performing in situ remedies. The target audience for this guidance and training course is: environmental consultants, responsible parties, federal and state regulators, as well as community and tribal stakeholders. This training will support users in efficiently and confidently applying the guidance at their remediation sites. An optimization case study is shared to illustrate the use of the associated guidance document. For more information and to register, see https://www.itrcweb.org or https://clu-in.org/live. PNNL's RemPlex Environmental Behavior and Remediation of Contaminated Sites with Cationic Radionuclides: The Cases of Cs and Sr - February 14, 2023, 1:00PM-2:00PM PST (21:00-22:00 GMT). Radioactive cesium (137Cs) and strontium (90Sr) are common contaminants in many environments around the world. This webinar by the Center for the Remediation of Complex Sites (RemPlex) features experts from around the world discussing the current understanding of Cs and Sr behavior in complex contaminated sites, including experimental, modeling, and monitoring data on the deposition, distribution, fate, and transport of these radionuclides; the role of permeable reactive barriers; and emerging remediation strategies for cationic radionuclides under different environmental conditions. For more information and to register, see https://www.pnnl.gov/projects/remplex/seminars. ITRC Vapor Intrusion Mitigation (VIM-1): A Two Part Series - February 14 and 21, 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. One Project, One Team: Lessons Learned in Military Munitions Response Program (MMRP) Contracting and Systematic Project Planning - February 15, 2023, 1:00PM-4:00PM EST (18:00-21:00 GMT). The M2S2 webinars have proven to be valuable forums to share information across the munitions response industry, on a wide range of topics and presented by a variety of subject matter experts representing multiple perspectives. Join this open forum as lessons learned are presented from the Government, Regulator and Contractor's side. Learn the best practices and challenges from each perspective, starting with the Systematic Planning Process from pre-proposal, to awarding the contract, and ultimately getting to the finish line.

ITRC Environmental Data Management (EDM): Real Life Application of Data Management Planning and Field Data Collection Best Practices - February 23, 2023, 1:00PM-2:30PM EST (18:00-19:30 GMT). 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. The additional offerings are scheduled for April and May of 2023. You are welcome to register for any of the three, but they do not build upon each other. For more information and to register, see https://www.itrcweb.org or https://clu-in.org/live. SERDP and ESTCP PFAS Leaching and Mobility at AFFF-Impacted Sites - February 23, 2023, 12:00PM-1:30PM EST (17:00-18:30 GMT). This webinar will feature DoD-funded research efforts to quantify PFAS leaching at AFFF-impacted sites. First, Dr. Jennifer Guelfo (Texas Tech University) will present her efforts to develop a standard PFAS leaching assessment methodology by optimizing three standard leaching methods. Second, Dr. Charles Schaefer (CDM Smith) will discuss his research into the relationship between PFAS concentrations measured in soil and those measured in porewater with the ultimate goal of facilitating site management.

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.

Geophysical methods measure physical properties of materials that can be used to infer information about the surface and subsurface of the Earth. These minimally invasive to non-invasive methods have been used in oil and mineral exploration since the early 1900s and modified over the past several decades to support the characterization and remediation of contaminated hazardous waste sites. Geophysical methods provide both quantitative and qualitative information. Properties such as electrical resistance, seismic reflection/refraction, or magnetism can be used to interpret geologic characteristics such as porosity, permeability, water content of the formation, and/or mineralogy. Geophysical data can also be used to identify the top of bedrock; other geologic contacts; geologic features, such as joints and faults; and buried objects, including drums and other potential subsurface sources of contamination and potential pathways for contaminant migration (such as more permeable layers in the subsurface). Visit the Geophysical Methods Focus Area: https://clu-in.org/geophysical Superfund Remedy Report, 17th Edition. The U.S. Environmental Protection Agency's (EPA) Office of Superfund Remediation and Technology Innovation prepared the Superfund Remedy Report (SRR) 17th Edition to share analyses of remediation technologies selected to address contamination at Superfund sites. EPA is particularly interested in documenting and disseminating information on treatment technologies to advance its mission of protecting human health and the environment. The report focuses on treatment as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) establishes a statutory preference for treatment.
