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 is excited to announce that they are now accepting proposals for new Project Teams to launch in 2025! The deadline to submit a proposal is May 15, 2024. They invite proposals from any agency, organization, company, or individual on any environmental topic. More information about ITRC Project Teams and the proposal process is available online including an electronic form and instructions for submitting Project Team proposals and frequently asked questions. To learn more and submit a proposal, please visit https://itrcweb.org/teams/planning.

ITRC Environmental Data Management (EDM): Best Practices for Exchanging Environmental Data Training - April 16 and 25, 2024, 1:00PM-2:30PM EDT (17:00-18:30 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. This is the final in a 3-part series. You are welcome to register for any of the series, but they do not build upon each other. For more information and to register, see https://www.itrcweb.org or https://www.clu-in.org/live. US EPA Superfund Remedial Program's Approach for Addressing Radioactive Contamination - April 17, 2024, 1:30PM-3:30PM EDT (17:30-19:30 GMT). The U.S. Environmental Protection Agency (EPA) Superfund program has developed regulations and guidance for remediating radioactively contaminated CERCLA sites. The focus of this presentation is an overview of EPA's recommended guidance documents on ARARs and risk assessment, models for conducting risk and dose assessments, and community involvement tools for engaging in meaningful involvement with the public that are intended to be used during the process to determine cleanup levels for radioactively contaminated Superfund sites. The presentation is intended to help the audience obtain knowledge of EPA's recommended guidance to facilitate cleanups that are consistent with how chemical contaminants are addressed, except where technical differences posed by radiation are addressed. The guidance and tools that are discussed in the presentation are freely available on the internet. This webinar provides an updated version of Module 3 that was presented in the ITRC webinar "Radiation Site Cleanup: CERCLA Requirements and Guidance" on June 5, 2007, an archive of which is available at https://www.clu-in.org/conf/itrc/radscleanup_060507/ .

In 2023, ITRC published the Sediment Cap Chemical Isolation Guidance to supplement the 2014 Contaminated Sediments Remediation Guidance with the goal of improving consistency in sediment cap performance outcomes. Sediment capping is a commonly selected remediation approach and numerous designs have been completed. Previous cap designs have been evaluated in multiple ways, and these varying approaches have led to some differences in selection of chemical design criteria, construction tolerance specifications, and monitoring/maintenance objectives for sites with similar characteristics and contaminants, leading to different expectations for long-term performance and reliability. The Sediment Cap Chemical Isolation Training will cover several key elements of the recommended framework.

EPA's Superfund Accomplishments Report highlights the important work of EPA staff and partners to clean up the nation's most contaminated land and respond to environmental emergencies and natural disasters. Superfund cleanups protect human health and the environment, while also supporting community revitalization efforts and economic opportunities through redevelopment. For more information, please visit https://www.epa.gov/superfund/superfund-accomplishments-quarterly-report-fiscal-year-2023 Sustainable Treatment System Caps Off Cleanup at Elizabeth Mine Superfund Site. The Elizabeth Mine site is an abandoned copper mine located in Vermont and was added to the Superfund National Priorities list in 2001. EPA researchers worked with a team of other experts on the cleanup efforts to solve complex problems at the abandoned mine site. For more information, please visit: https://www.epa.gov/sciencematters/sustainable-treatment-system-caps-cleanup-elizabeth-mine-superfund-site Research Brief 351: Using Earth Materials to Remove Metals Near Abandoned Mines. NIEHS Superfund Research Program (SRP)-funded researchers developed a new strategy that uses limestone and a naturally occurring mineral to clean up water contaminated with arsenic and uranium - two of the most frequently detected drinking water pollutants in Tribal communities. More than 600,000 American Indians in the Southwestern U.S. are estimated to live within six miles of an abandoned mining site, which can contain mixtures of arsenic, uranium, and other toxic elements. These contaminants can pollute the local air, water, and soil. For more information, please visit https://tools.niehs.nih.gov/srp/researchbriefs/view.cfm?Brief_ID=351 Superfund Research Program Technology Profile March 2024. Researchers at the University of Iowa are investigating how biochar, the carbon-rich byproduct of burning plant matter, can enhance the performance of a type of bacteria - called organohalide-respiring bacteria (OHRB) - commonly used to break down halogenated pollutants. Chlorinated ethenes, a type of halogenated pollutants, are among the most frequently detected contaminants in aquatic ecosystems across the U.S. OHRB is not able to fully degrade halogenated pollutants in the field. To address this limitation, the team is developing a platform to tailor the properties of biochar to increase the ability of OHRB to break down chlorinated ethenes into non-toxic substances.

Remediation Management for Local and Wide-spread PFAS Contamination (2020). This publication (report number FB000332/ENG) was produced by the German Federal Environment Agency. PFAS - as a group of substances - are becoming increasingly important in the treatment of contaminated sites and harmful soil changes. The present work aid "Remediation management for local and area-wide PFAS contaminations" supports the responsible authorities in the pre-selection, evaluation and decision for a suitable and proportionate remediation procedure, shows relevant basic conditions and accompanying measures. Due to the different substance properties of PFAS, the possible remediation procedures must also be evaluated on a substance-specific basis. The advantages and disadvantages, the technical and approval requirements as well as their sustainability are shown for the possible remediation methods.

Federal Remediation Technologies Roundtable (FRTR): Spring 2024 General Meeting - May 21, 2024, Washington, D.C. and online. In this meeting, FRTR member agencies will revisit artificial intelligence (AI) and machine learning (ML), discussed previously at the Spring 2022 General Meeting. This meeting will focus on progress and results of recent projects providing advanced contaminant plume characterization and predictive modeling, and improved cleanup efficiency. Presentations will highlight case studies where AI/ML has substantially enhanced remedial decisions, remedy implementation and performance monitoring, and reduced needs for extensive sampling. Discussions during the meeting will provide remedial project managers and technical staff with information and best practices for deploying AI/ML technology. Two public attendance options will be available - attending in-person in Washington, D.C. and attending virtually via Zoom. Registration will open soon.
