> Grant Announcement
Applicants Selected for FY 2022 Brownfields Assessment, RLF, Cleanup (ARC) Grants and RLF Supplemental Funding. In May, EPA announced that 227 communities
were selected to receive 237 grant awards for a total of $147.5 million in Brownfields Assessment, Revolving Loan Fund, and Cleanup Grant funding.
These Brownfields Grants will be used to assess, clean up and redevelop underutilized properties while protecting public health and the environment.
Brownfields Grants not only support economic growth and job creation, but they also empower communities to address the environmental, public health, and
social issues associated with contaminated land. EPA also announced $107 million in supplemental funding to 39 successful, existing Revolving Loan Fund
Grant recipients who have demonstrated success in their work to clean up and redevelop brownfield sites. Supplemental funding for RLF Grants is available
to recipients that have depleted their funds and have viable cleanup projects ready for work. RLF supplemental funding helps sustain and increase
the great progress these communities have made in cleaning up brownfield sites, while also helping them become stronger, healthier, and more economically
competitive. For more information, please visit https://www.epa.gov/brownfields/applican ...

Vapor Intrusion Mitigation (VIM-1) - A Two Part Series, June 2 and 14, 2022. 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
SERDP ESTCP: Demonstration and Validation of New Non-Invasive Technology to Assess Contaminant Storage in Low Permeability Media and Rock Matrix June
2, 2022. This webinar will feature DoD-funded research efforts to demonstrate geophysical approaches for estimating the rate coefficient governing dual-domain
mass transfer (DDMT) as well as immobile porosity. Dr. Ramona Iery (NAVFAC Engineering and Expeditionary Warfare Center will cover the basis for monitoring
DDMT using geoelectrical measurements. Then, Dr. Lee Slater (Rutgers University) will talk about the teams new borehole technology, the Mobile/Immobile
Porosity Exchange Tool (MI-PET). Finally, Dr. Fred Day-Lewis (Pacific Northwest National Laboratory) will demonstrate how geophysical methods can be used
to constrain parameter estimation for DDMT. For more information and to register please visit https://www.serdp-estcp.org/Tools-and-Tr ...
Spring 2022 FRTR Meeting - June 6 and 13, 2022. The FRTR Spring 2022 Meeting will explore advances in applying artificial intelligence technologies to site
cleanup. Artificial intelligence technologies are beginning to transform how people and machines work together. Robotics and unmanned systems provide
opportunities to access dangerous or toxic environments, and improve worker safety. Advances in machine learning are making it possible to process and analyze
large data sets in new ways to support remediation decisions. Specific objectives are: Review recent technology advances supporting site characterization
and remediation, identify potential benefits, risks and limits of robotics and unmanned aerial systems to support site characterization and remediation,
and discuss appropriate use of machine learning and artificial intelligence to support remediation decisions. For more information and to register please
Connecting the Science to Managing LNAPL Sites a 3 Part Series - June 7 and 21, 2022. The newly updated LNAPLs (Light Non-Aqueous Phase Liquids) 3-part training
course series is based on the ITRC guidance: LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018) and focuses
on connecting the science to managing LNAPL sites and helping you: build upon your understanding of LNAPL behavior in the subsurface (Part 1), develop your
LNAPL conceptual site model and LNAPL remedial goals (Part 2), and select/implement LNAPL technologies (Part 3). After this training series, the expectation
is that you will have the skills and understanding to use ITRC science-based resources to improve decision making at your LNAPL sites. For regulators and other
government agency staff, this improved understanding can hopefully be incorporated into your own LNAPL programs. It is expected that participants will attend
this 3-part training series in sequence. For more information and to register, see https://www.itrcweb.org or https://clu-in.org/live.
Federal Facilities Online Academy: Resolving Issues before Formal Dispute - June 8, 2022, 1:00PM-3:00PM EDT (17:00-19:00 GMT). Resolving Issues Before
Formal Dispute is a two-hour webinar course that identifies less formal options to address conflict before going to dispute under a federal facility agreement.
This webinar provides project management tips and techniques to address disagreements early in the process . By taking this course, participants will achieve
the following objectives: Identify factors that contribute to conflict when working with team members from different agencies; Learn how to prepare a team
to handle conflict; Explore tips and techniques to improve communication and come to resolution; and, Understand when formal dispute should be considered.

ITRC Soil Background and Risk Assessment (SBR) - June 23, 2022, 1:00PM-2:30PM EDT (17:00-18:30 GMT). While some state and federal agencies and other entities
have guidance documents regarding soil background, there is not one comprehensive and widely accepted guidance document that summarizes the state of the
science on this topic. The Soil Background and Risk Assessment ITRC guidance document released December 2021 is intended to fill the gap by providing a comprehensive
defensible framework for establishing and using soil background in risk assessments. It focuses on the process of establishing defensible background concentrations
of naturally occurring or anthropogenic ambient chemicals that can be used when performing risk assessment at contaminated sites. The target audience for
the ITRC Soil Background and Risk Assessment Guidance Document (SBR-1) includes risk assessors, risk managers, and site investigators, which may include
federal, state, tribal, and various local agency employees; contractors to these agencies; as well as potentially liable parties and their consultants.
For training purposes, the ITRC Soil Background and Risk Assessment team produced four videos, two of which will be viewed during the class. For more information
and to register, see https://www.itrcweb.org or https://clu-in.org/live.
> New Documents and Web Resources
Updated Solidification/Stabilization Focus Area. Solidification and stabilization are treatment technologies that achieve remediation goals by mixing
contaminated materials with reagents that reduce leaching, and thus mobility, of the contaminants. Rain, stormwater runoff, and groundwater flow can leach
contaminants from soil, sludge, and other wastes in the environment and transport them to groundwater or nearby surface water bodies, increasing potential
exposure pathways for human and ecological receptors. The CLU-IN Solidification/Stabilization (S/S) Focus Area has been updated to reflect the current
state of the science, including new screening questions for considering S/S as a remedy. Visit the updated Focus Area at https://clu-in.org/solidification
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
