Rural community residents and leaders often wish to revitalize their downtowns but do not know where to start or how to pay for the needed planning and infrastructure
to move development forward. Written through the lens of rural Appalachia, the revitalization approaches described in the Downtown Revitalization Playbook
can be used by small communities across the United States. Rural downtowns often include properties with contaminant concerns, including brownfields and
Superfund sites. The health and safety challenges posed by these contaminated spaces, alongside vacant storefronts and empty gathering places, reinforce
downtown disinvestment. The playbook provides practical steps to organize a local team with the right mix of skills to reimagine, initiate and attract investment
back to rural downtowns. For more information and to register, see ITRC Strategies for Preventing and Managing Harmful Cyanobacteria Blooms (Two Part Series) - October 5 and 12, 2023. Cyanobacteria are microscopic, photosynthetic
organisms that occur naturally in all aquatic systems but most often in freshwater systems. Under certain conditions, cyanobacteria can multiply and become
very abundant, discoloring the water throughout a water body or accumulating at the surface. These occurrences are known as blooms. Cyanobacteria may produce
potent toxins (cyanotoxins) that pose a threat to human health. They can also harm wildlife and domestic animals, aquatic ecosystems, and local economies
by disrupting drinking water systems and source waters, recreational uses, commercial and recreational fishing, and property values. It is likely that continued
population growth, land use change, increases in nutrient inputs to our waterways, and the warming climate will favor proliferation of these problematic
species. Providing a range of practical approaches to minimize these blooms and their likely societal and wildlife effects is critical to our future vitality,
health, and economic prosperity. For more information and to register, see or Tools for PFAS Site Characterization Webinar Series - October 6, 20, and November 8, 2023. The NIEHS Superfund Research Program (SRP) is sponsoring a Risk
e-Learning webinar series, hosted by CLU-IN, focused on research efforts to develop tools for sampling, monitoring, detecting, and characterizing per-
and polyfluoroalkyl substances (PFAS) contamination. The three-part series will feature SRP-funded researchers and collaborators whose research focuses,
in part, on understanding the distribution and fate of PFAS in the environment. To learn more about each session and to register, see
ITRC Sustainable Resilient Remediation (SRR) - October 10, 2023, 1:00PM-3:15PM EDT (17:00-19:15 GMT). Extreme weather events and wildfires are increasing
and impacting hazardous waste sites. The primary goal of cleanups, which is protecting human health and the environment, is undermined. Confronted with these
risks, environmental professionals should assess, and design remedies that are sustainable and resilient. Sustainable resilient remediation (SRR) is
an optimized solution to cleaning up and reusing a hazardous waste site that limits negative environmental impacts, maximizes social and economic benefits,
and creates resilience against increasing threats. The objective of the ITRC Sustainable Resilient Remediation (SRR-1) is to provide resources and tools
for regulators, stakeholders, consultants, and responsible parties to help integrate sustainable and resilient practices into remediation projects.
This guidance updates the Interstate Technology and Regulatory Council's (ITRC) Technical and Regulatory Guidance: Green and Sustainable Remediation:
A Practical Framework (ITRC 2011a) and includes a strong resilience component to address the increasing threat of extreme weather events and wildfires. Recommendations
for careful and continuous consideration of the social and economic costs and benefits of a cleanup project are included. For more information and to register,
see or Introduction to the Hazard Ranking System (HRS) - October 26, 2023, 11:00AM-4:00PM EDT (15:00-20:00 GMT). This course is for those with limited exposure
to the HRS and those needing a refresher prior to performing an HRS site evaluation. This course will provide an introduction to the HRS by presenting overviews
of its role in the Superfund program and site assessment process and its structure. This training will also provide overviews of the HRS factor categories (Likelihood
of Release/Exposure, Waste Characteristics, Targets), including their general structure and the concepts and processes involved in scoring. This session
is designed for Environmental professionals that conduct HRS evaluations as part of EPA site assessment in evaluating sites for the National Priorities List
(NPL). The live session will include a 1 hour break. For more information and to register, see Introduction to Brownfield All Appropriate Inquiries - October 30, 2023, 3:00PM-4:30PM EDT (19:00-21:30 GMT). The brownfield amendments to CERCLA and
the recent Brownfields Utilization, Investment and Local Development (BUILD) Act provide liability protections for certain landowners and potential property
owners who did not cause or contribute to contamination at the property. This webinar offers an introduction or refresher on All Appropriate Inquiry (AAI),
the process of evaluating a property's environmental conditions and assessing potential liability for any contamination. For more information and to register,
see Soil Background & Risk Assessment- November 2, 2023, 1:00PM-3:00PM EDT (17:00-19:00 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

by a certain bacterium, according to researchers funded by the NIEHS Superfund Research Program. The study could inform bioremediation efforts that harness
the microbe, known as Acidimicrobium Strain A6, for cleaning up contaminated soil, sediments, and aquifers. Distinctive PFAS properties, such as high heat
tolerance and oil resistance, stem from exceptionally stable bonds between carbon and fluorine atoms. Because PFAS resist breakdown, they can accumulate
in exposed organisms and ecosystems, posing a risk to human and environmental health. View and download the brief at ...

NAVFAC Report: Case Studies Using Surface Weighted Average Concentration Methods at Sediment Remediation Sites May 2023 (TR-NAVFAC-EXWC-SH-2315).
Surface weighted average concentrations (SWACs) can be used to estimate mean contaminant concentrations over a specified area using contaminant data collected
over different temporal and spatial scales. The SWAC method is used to reduce the influence of sampling bias and interpolate contaminant of concern concentrations
in areas with limited sampling locations. SWAC methodologies can also be used to define remedial footprints in the Feasibility Study and evaluate remedy effectiveness.
SWACs are an increasingly common approach for assessing compliance with remediation goals at contaminated sediment sites. Navy and United States Environmental
Protection Agency case studies are included to highlight the use of SWACs at sediment sites. View and download the report from ...

Remediation Technologies Roundtable (FRTR) will be Recent Advances in PFAS Characterization Technologies. The science and technology of site characterization
for per-and polyfluoroalkyl substances (PFAS) has advanced in the five years since FRTR last addressed the topic in 2018. Federal agency budgets for PFAS remediation
have grown substantially during this time. As a result, site characterization efforts such as Remedial Investigations, as well as early response actions,
are underway at many Federal facilities. Funding for field-scale projects to further advance PFAS characterization technology and methodologies also has
increased substantially. The FRTR 2023 Fall General Meeting provides an opportunity for member agencies to share results of recent and on-going PFAS projects
that are improving our understanding of PFAS characterization technologies. Specifically, invited presentations and roundtable discussions will explore
current best practices for PFAS site characterization, emerging technologies and methods, case studies and current agency needs for technology transfer
and future research. FRTR member-agencies meet semi-annually, usually in the Washington, D.C. area. These meetings are open to the public. For more information
