Welcome to TechDirect! Since the May 1 message, TechDirect gained 95 new subscribers for a total of 44,502. 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. 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. Request for Information (RFI): US EPA Superfund Contract Laboratory Program, Superfund Analytical Methods (SFAM) Procurement. The purpose of this RFI is to gather information from industry in the preparation for an upcoming solicitation for the Superfund Analytical Methods (SFAM02.0) under the Contract Laboratory Program (CLP). The NAICS Code for this requirement is 541380 - Testing Laboratories and Services. Responses are due by 4:30 PM ET on June 5, 2025. For more information and to register to receive updates, see https://www.fedconnect.net/FedConnect/?doc=68HERH25R0010&agency=EPA. ITRC: PFAS Beyond the Basics: PFAS Treatment Technologies Training - Tuesday, June 3, 2025, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This training class builds on the earlier information for treatment technologies presented in the PFAS 101 CLU-IN training. It provides more in-depth information regarding considerations for implementing integrated PFAS treatment technologies and remediation strategies. This training introduces the concept that achieving site remedial objectives will likely necessitate the implementation of multiple treatment technologies and remediation strategies (i.e., an integrated remedial strategy). Specifically, this training uses a hypothetical conceptual site model to frame the discussion of remedial approaches for PFAS impacted source area soil, source area groundwater, and more dilute groundwater plumes. The training concludes with a discussion of select field implemented and developing disposal and destructive technologies for managing treatment residuals.

RemPlex: Subsurface Sensing: Advancing Electrical Geophysical Techniques for Non-Invasive Characterization and Monitoring at Complex Sites - Tuesday June 3, 2025, 11:00AM-12:30PM EDT (15:00-17:30 GMT). Explore the application of geophysical techniques for understanding, characterizing and monitoring complex remediation sites, with a special focus on the Spectral Induced Polarization (SIP) method. SIP is an exciting emerging geophysical technology that can offer unique non-invasive information on both the physical and geochemical conditions of the subsurface-particularly in environments where contamination and heterogeneous geological conditions pose significant challenges to collecting data at relevant spatial and temporal scales. The seminar will highlight recent advancements in both lab-scale analysis of SIP signals and their field-scale applications. Presented by the Center for the Remediation of Complex Sites (RemPlex). For more information and to register, see https://www.pnnl.gov/remplex-seminars. ITRC: Microplastics Training - Tuesday, June 10, 2025, 1:00PM-3:00PM EST (17:00-19:00 GMT). 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. The online ITRC Guidance Document is geared toward an audience with reasonable level of scientific understanding, but not microplastic-specific knowledge. The guidance provides a user with information on microplastics and the state of the applied science without having to go to the scientific literature. The target audience for the guidance and this training course includes state regulators and environmental consultants, as well as community and tribal stakeholders. 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. Recent issues, complete archives, and subscription information is available at https://clu-in.org/products/tins/. The following resource was included in recent issues:
Technology Profile - Phytotechnology (EPA/600/R-25/137, May 2025). EPA Office of Land and Emergency Management (OLEM) and the Office Research and Development (ORD) collaborated in the development of the Phytotechnology technology profile, recently published as a major update to the "Phytotechnologies for Site Cleanup" Fact Sheet (EPA 542-F-10-009, September 2010) due to a number of advancements in the science. The technology profile was designed to help contaminated sites technical staff and site managers to understand the mechanisms of phytotechnologies and assess their applicability to remediate or control contaminants in various media. Also included are case study examples and useful information for planning a phytotechnology application (e.g., successful plant-contaminant combinations, operation and maintenance (O&M), and long-term monitoring). View or download the recently published technology profile from https://cfpub.epa.gov/si/si_public_record_Report.cfm?dirEntryId=366104&Lab=CESER. Vertical Delineation of Contamination in Aquifers Discussed at Workshop Report (2025). RemPlex collaborated with the United Kingdom's Nuclear Decommissioning Authority (NDA) to host a two-day workshop focused on the challenge of vertical delineation of contamination in aquifers underlying and/or impacted by complex sites. The workshop brought together an international group of researchers, site operators, government agency staff, practitioners, and regulators to identify challenges and potential solutions to enable the design and optimization of targeted remedies and groundwater monitoring programs. View or download the report from https://www.pnnl.gov/projects/remplex/workshops. Archived Webinar from NEWMOA: Introduction to Downhole Geophysical Investigations - Applications to Contaminated Groundwater Sites. Northeast Waste Management Officials' Association (NEWMOA) hosted this webinar in February 2025. The session explained the types of downhole geophysical methods available and how they can be used to develop and enhance conceptual site models and analyze complex geology. The presentation reviewed geophysical logs and highlight unique geography and identification of geological features. View or replay the archived webinar at https://www.newmoa.org/event/downhole-geophysics-webinar/. ContaminatedLand.info.
