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. Evaluating Plant Uptake of Chemical Contaminants in Crops Grown Near Urban Gardening Sites for Human Health Risk Assessment - August 9, 2023, 1:00PM-3:00PM EDT (17:00-19:00 GMT). This seminar, postponed from July, aims to provide an assessment of the potential exposure routes, plant uptake pathways, and remediation practices of chemicals contaminants found in crops grown in urban gardening sites. It will focus on both inorganic and organic pollutants that are considered contaminants of emerging concern (CECs) by the U.S. EPA. The presence of several trace elements and persistent organic pollutants (POPs) in urban soil media were analyzed on the state-level to quantify the potential contamination risk associated with plant uptake mechanisms by crops commonly grown throughout the various regions of the U.S. CECs exposure routes in urban agriculture (UA) scenarios and associated human health risks are assessed. This seminar also serves to provide potential remediation methods for polluted urban soils, with an emphasis on affordability, accessibility, and sustainability of the methods.

First, Dr. Jennifer Weidhaas (University of Utah) will present her research results on developing more efficient, cost effective, and sustainable treatment trains for mixed munitions wastewater. Second, Mr. Brian Hubbard (U.S. Army Program Executive Office Ammunition) will discuss the development, scale-up, and results from several field demonstrations of a technology capable of rapidly and completely destroying insensitive munition constituents in explosives production wastewater.For more information and to register, please visit https://serdp-estcp.org/webinars. PNNL's RemPlex and IAEA "Assessing Environmental Remediation Technologies: Soils" - August 15, 2023, 11:00AM-12:30PM EDT (15:00-16:30 GMT). At any given site, selection of the most appropriate remedial alternative is driven by a variety of environmental, technical, economic, social, regulatory, and policy-driven factors. Panelists Bruce Marvin and Norbert Molitor will discuss aspects of remediation technologies-such as efficiency, effectiveness, sustainability, maturity and availability, complexity, plus long-term maintenance and monitoring requirements-to be considered in the selection of a given soil remediation approach. The seminar will cover technologies that are available to treat a broad array of contaminant categories (radionuclides, metals and organics).

SERDP ESTCP Developing and Demonstrating PFAS Passive Samplers - August 24, 2023, 12:00PM-1:00PM EDT (16:00-17:00 GMT). This webinar will feature DoD-funded research efforts to develop and demonstrate PFAS passive samplers. First, Dr. Lee Blaney (University of Maryland, Baltimore County) will discuss the development and performance of anion exchange membranes as passive samplers for PFAS. Second, Dr. Paul Edmiston (The College of Wooster) will talk about the development of the Sentinel passive sampler and its use for groundwater, surface water, and stormwater monitoring.

Recent Advances in Consideration of Ecosystem Services in Contaminated Clean-Ups and Risk Assessments - August 31, 2023, 1:00PM-2:30PM EDT (17:00-18:30 GMT). This webinar will introduce some recent advances in consideration of ecosystem services in contaminated site cleanups. The team will introduce concepts, tools, and example applications. Then the audience will be shown how to find newly available resources and places to turn to for consideration of ecosystem services in their cleanup efforts.

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. In Situ Thermal Remediation (EPA 600-R-23-062). The purpose of this paper is to briefly describe these commonly used in situ thermal remediation technologies, and how they are deployed to remediate VOC and SVOC contaminated sites. The effects of temperature on the physical properties of common organic contaminants that result in the effectiveness of these technologies for the recovery or destruction of contaminants are also briefly described. A case study is provided for each of the thermal technologies discussed. In addition, guidance is provided on evaluating, contracting, and implementing thermal technologies within the Superfund process of evaluating alternative technologies, including preparing bid documents for thermal remediation services, reviewing designs, and monitoring the implementation of the remedy.
