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. Please feel free to reply to this email or share your comments online with feedback on your utilization of the TechDirect service or recommendations for future editions. 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. RemPlex: The Hidden Costs of PFAS Remediation: Energy, Waste, and Long-Term Viability - Tuesday, August 19, 2025, 1:00PM-2:30PM EDT (18:00-19:30 GMT). PFAS management presents many complex challenges, from uncertainties about human health risks and contaminant behavior to the effectiveness of remedies and the demands of evolving regulatory frameworks. The seminar will explore the environmental footprint of treating per- and polyfluoroalkyl substances (PFAS), with discussion about the energy demands, waste generation, and broader environmental impacts of PFAS treatment technologies and insights into how these factors-alongside the regulatory context-should shape decision-making around remediation. Co-presented by the Center for the Remediation of Complex Sites (RemPlex) and the Sustainable Remediation Forum (SURF).

Virtual Technology Fair: Heavy Metals Detection and Treatment for Water - Wednesday, August 27, 2025, 1:00PM-2:30PM EDT (17:00-18:30 GMT). The NIEHS Superfund Research Program (SRP) presents a "Virtual Technology Fair" featuring Small Business Innovative Research (SBIR) grant recipients developing innovative solutions for heavy metals in water. Speakers will give a "pitch", showcasing the work underway and its value-added to disrupt the market. We encourage participation by and questions from potential end-users, customers, and other stakeholders to accelerate technology transfer of these promising approaches. The August 27th webinar will feature ChemFinity Technologies, Inc. on "Remediation of acid mine drainage water using selective metal-harvesting membranes;" OndaVia, Inc. on "Automated, In-Line Hexavalent Chromium Analyzer;" Microvi Biotechnologies, Inc. on "Intensified, High-Rate Reductive Immobilization of Hexavalent Chromium;" Picoyune on "Plasmonic Sensor and Field Monitor for Mercury."

This webinar will look at stages of the RI/FS, from RMM through the FS. Presentations will discuss how to create risk scenarios for evaluation using the Risk Management Methodology (RMM) and explain how that can influence the development of remedial alternatives by considering both contamination and land use. The presentations will look at an example site and at a case study. We will also discuss the use of "FS alternatives panels" to facilitate the development of remedial alternatives and attempt to get buy-in from various members of the project team. For more information and to register, see https://www.clu-in.org/live. ITRC: Pump & Treat Optimization - Thursday, September 4, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This training aims to summarize existing information and best practices while also developing a systemic and adaptive optimization framework specifically for P&T well-network design and management. The primary audience for this training is environmental project decision-makers, which may include federal, state, tribal, and various local agency employees; contractors to these agencies; and potentially liable parties and their engineers and consultants as well as involved stakeholders. Generally, those involved in designing, building and operating, and optimizing pump & treat systems would benefit.The goal of the training is to provide a roadmap for optimizing a P&T system and refining the remedial strategy or shifting toward another remedial approach. Pump & Treat optimization should be systematic and data-based, and the training and document aim to provide tools and direction to assist in this rigorous process. For more information and to register, see https://www.itrcweb.org or https://www.clu-in.org/live. 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.
