Risk Communication Strategies to Reduce Exposures and Improve Health: Session III - Engaging Communities and Tailoring Messages to Advance Equity and Justice

The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on strategies to communicate potential environmental health risks to reduce exposures and improve health.
The four-part series will showcase effective risk communication strategies and how they have been tailored to the needs of diverse communities. Presentations will also highlight first-hand experiences designing risk communication messages and campaigns, evaluating impact, and adapting communication strategies for different populations. The webinar series builds on an SRP workshop held in June 2021.

In the third session, presenters will discuss how they have engaged and communicated with underserved and vulnerable communities and developed strategies to tailor messages to these communities so they can participate and use the information equitably. The session will also include a presentation on the NIH Rapid Acceleration of Diagnostic-Underserved Populations (RADx-UP) Program, which funds community engagement programs with a focus on communities most affected by the COVID-19 pandemic.

Sharon Croisant, Ph.D., University of Texas Medical Branch and the Baylor College of Medicine SRP Center, will describe the access and equity issues environmental justice communities face, such as risk of exposure due to residence or occupation, and status as migrants and immigrants. Disasters frequently disproportionately impact these populations, exacerbating existing inequities and injustices and contributing to stress, which often serves as a barrier to risk communication. We will discuss barriers to risk communication under emergent conditions and strategies for improving communication to reduce exposures.

Louie Rivers, Ph.D., of North Carolina State University, will discuss his work engage with communities in Southeast Raleigh through the Walnut Creek Wetland Community Project. This presentation will highlight the process of engaging residents through focused groups and meetings to assess stream conditions in neighborhoods, support interests in green infrastructure, and increase environmental awareness.

Al Richmond, M.S.W., Executive Director of Community-Campus Partnerships for Health (CCPH), will describe phase one of a COVID19 at-home testing project coordinated by the RADx UP Coordinating Data Collection Center. The Say Yes! COVID Test Project centers local community engagement strategies to reach underserved populations and promote confidence in addressing barriers to testing and vaccination. Lessons Learned from the public health intervention, including the novel approaches to social media will be highlighted

Risk Communication Strategies to Reduce Exposures and Improve Health: Session IV - Communication Toolkits to Communicate Environmental Risks

The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on strategies to communicate potential environmental health risks to reduce exposures and improve health.
The four-part series will showcase effective risk communication strategies and how they have been tailored to the needs of diverse communities. Presentations will also highlight first-hand experiences designing risk communication messages and campaigns, evaluating impact, and adapting communication strategies for different populations. The webinar series builds on an SRP workshop held in June 2021.

The fourth and final session will feature work by SRP-funded researchers who are translating research into communication tools and tailoring them for specific community needs. These specialized tools work to successfully communicate health risks and increase environmental health literacy.

BJ Cummings, M.A., and Lisa Hayward Watts, Ph.D., of the University of Washington SRP Center, will discuss how community and agency partners were involved in developing multilingual videos as the preferred tool for communication of risk from fishing in the Lower Duwamish Waterway Superfund Site. Presenters will emphasize the empowerment process used to select and develop the project. We will also discuss challenges in resolving different risk perspectives and messaging needs and how we've adapted our approach in subsequent projects.

Julia Brody, Ph.D., of Silent Spring Institute, and Phil Brown, Ph.D., of the Northeastern University SRP Center, will describe the process of reporting back personal biomonitoring and environmental exposure results. Examples will range from their earliest paper-based methods to their Digital Exposure Environmental Report Back Interface (DERBI) in its computer and smartphone versions. They will also address elements of training clinicians to use report-back methods.

Kathleen Gray, Ph.D., Sarah Yelton, M.S., and Megan Rodgers, M.E.A., of the University of North Carolina at Chapel Hill SRP Center will share their process for collaborating with diverse partners to communicate about potential environmental health risks. Featured projects address fish consumption advisories, toxic metals contamination of well water, and PFAS in water and air.

Characterization and Remediation of Fractured Rock

Interstate Technology Regulatory Council

Characterization and remediation of contaminated groundwater in fractured rock has not been conducted or studied as broadly as groundwater at unconsolidated porous media sites. This unfamiliarity and lack of experience can make fractured rock sites perplexing. This situation is especially true in portions of the U.S. where bedrock aquifers are a primary source of drinking and process water, and demands on water are increasing. As a result, remedial activities often default to containment of contaminant plumes, point of use treatment and long-term monitoring rather than active reduction of risk. However, this attitude does not incorporate recent advances in the science and technology of fractured rock site characterization and remediation.

The basis for this training course is the ITRC guidance: Characterization and Remediation of Fractured Rock. The purpose of this guidance is to dispel the belief that fractured rock sites are too complex to characterize and remediate. The physical, chemical and contaminant transport concepts in fractured rock have similarities to unconsolidated porous media, yet there are important differences. These differences are the focus of this guidance.

By participating in this training class, you should learn to:

  • Use ITRC's Fractured Rock Document to guide your decision making so you can:
    • Develop quality Conceptual Site Models (CSMs) for fractured rock sites

    • Set realistic remedial objectives

    • Select the best remedial options

    • Monitor remedial progress and assess results
  • Value an interdisciplinary site team approach to bring collective expertise to improve decision making and to have confidence when going beyond containment and monitoring - - to actually remediating fractured rock sites.

Case studies of successful fractured rock remediation are presented to provide examples of how fractured rock sites can be evaluated and available tools applied to characterization and remediation.

Training participants are encouraged to view the associated ITRC guidance, Characterization and Remediation of Fractured Rock prior to attending the class.

Integrated DNAPL Site Characterization

Interstate Technology Regulatory Council Sites contaminated with dense nonaqueous phase liquids (DNAPLs) and DNAPL mixtures present significant environmental challenges. Despite the decades spent on characterizing and attempting to remediate DNAPL sites, substantial risk remains. Inadequate characterization of site geology as well as the distribution, characteristics, and behavior of contaminants -- by relying on traditional monitoring well methods rather than more innovative and integrated approaches -- has limited the success of many remediation efforts.

The Integrated DNAPL Site Characterization Team has synthesized the knowledge about DNAPL site characterization and remediation acquired over the past several decades, and has integrated that information into a new document, Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015). This guidance is a resource to inform regulators, responsible parties, other problem holders, consultants, community stakeholders, and other interested parties of the critical concepts related to characterization approaches and tools for collecting subsurface data at DNAPL sites. After this associated training, participants will be able to use the ITRC Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015) guidance to develop and support an integrated approach to DNAPL site characterization, including:
  • Identify what site conditions must be considered when developing an informative DNAPL conceptual site model (CSM)
  • Define an objectives-based DNAPL characterization strategy
  • Understand what tools and resources are available to improve the identification, collection, and evaluation of appropriate site characterization data
  • Navigate the DNAPL characterization tools table and select appropriate technologies to fill site-specific data gaps

For reference during the training class, participants should have a copy of Figure 4-1, the integrated site characterization flow diagram from the ITRC Technical and Regulatory Guidance document: Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015) and available as a PDF at http://www.cluin.org/conf/itrc/IDSC/ITRC-ISC-Figures.pdf

Connecting the Science to Managing LNAPL Sites a 3 Part Series: Part 1

Interstate Technology Regulatory Council Connecting the Science to Managing LNAPL Sites - 3-Part Series

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)
  • 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 recommended that participants have a general understanding of hydrogeology and some familiarity with petroleum contaminated sites. The courses will build on your existing LNAPL knowledge and outline the framework for making LNAPL remediation and management decisions. It is expected that participants will attend this 3-part training series in sequence.

LNAPL Training Part 1: Understanding LNAPL Behavior in the Subsurface
Part 1 teaches how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1:
  • Explains what LNAPL data can tell you about the LNAPL and site conditions
  • Covers how that information is applied to the development of an LNAPL conceptual site model (LCSM) (Part 2) and LNAPL technology selection (Part 3)

Relevant and practical examples are used to illustrate key concepts.

LNAPL Training Part 2: LNAPL Conceptual Site Models and the LNAPL Decision Process
Part 2 teaches participants how to develop an LNAPL conceptual site model (LCSM) and the overall framework for making LNAPL remediation and management decisions. Part 2:
  • Discusses key LNAPL and site data
  • Explains when and why those data may be important
  • Covers how to effectively organize the data into an LCSM

Part 2 also discusses how to address LNAPL concerns by selecting appropriate goals and objectives, choosing applicable technologies, and assigning remedial performance metrics and endpoints.

LNAPL Training Part 3: Using LNAPL Science, the LCSM, and LNAPL Goals to Select an LNAPL Remedial Technology
Part 3 of the training teaches the importance of informed remedial technology selection and appropriate technology application. Part 3:
  • Discusses remedial technology groups
  • Introduces specific and new remedial technologies
  • Reviews the technology selection process, how technologies can be combined to accelerate cleanup, and how the LCSM informs selection

A case study and examples demonstrate the use of these tools for remedial technology selection, implementation, and demonstration of successful remediation.

Training participants are encouraged to view the associated ITRC guidance, LNAPL Site Management: LCSM Evolution, Decision Process, and Remedial Technologies (LNAPL-3, 2018), prior to attending the class.

Optimizing Injection Strategies and In situ Remediation Performance

Interstate Technology Regulatory Council In situ remediation technologies using amendment injections have advanced to mainstream acceptance and offer a competitive advantage over many forms of ex situ treatment of soil and groundwater. Developing a detailed site-specific strategy is absolutely critical to the success of such in situ remedies. These strategies include conducting a thorough site characterization that will allow development of a detailed Conceptual Site Model (CSM) to guide critical analysis of subsurface features and improving remediation effectiveness. In the interest of developing expedited solutions, many past in situ remediation projects have been executed based on an incomplete understanding of the hydrogeology, geology, and contaminant distribution and mass. Some of these sites have undergone multiple rounds of in situ injections but have not advanced to closure. Better strategies and minimum design standards are required to decrease uncertainty and improve remedy effectiveness.

In an effort to overcome these challenges and improve the effectiveness of in situ remediation using injected amendments, ITRC developed the guidance: Optimizing Injection Strategies and In Situ Remediation Performance (OIS-ISRP-1). The guidance and this associated training course 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 underperforming 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.

Prior to attending the training class, participants are encouraged to view the associated ITRC guidance, Optimizing Injection Strategies and In Situ Remediation Performance (OIS-ISRP-1) as well as to be familiar with the characterization process described in Integrated DNAPL Site Strategy (ITRC 2011c).

Sustainable Resilient Remediation (SRR)

Interstate Technology Regulatory Council

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.

Training Objectives


  • Educate participants about available SRR resources and tools
  • Impart evolution from Green and Sustainable Remediation (GSR) to SRR
  • Provide guidance on practical application and implementation of SRR
  • Provide participants with information necessary to navigate the SRR guidance and tools

Training Goals

  • Provide information and resources for the social and economic dimensions of sustainability, including state-of-the-art social and economic evaluation tools
  • Provide a framework illustrating how and why sustainability and resilience should be integrated throughout the remedial project life cycle
  • Offer checklists of key sustainable best management practices to address resilience based on specific vulnerabilities at a site, as well as resources for additional information
  • Present interactive maps with links to available state and federal resources to quickly find examples and best practices from your state or other states and federal agencies
  • Reference case studies illustrating the application of SRR considerations

After the SRR Training, a user will have the tools necessary to understand what SRR is and how it can be used to achieve a sustainable and resilient remediation outcome. This can be accomplished by remediation practitioners applying the principles and practices to a contaminated site and by providing SRR resources to help regulators and stakeholders in the development and review of project documents or submittals.

The intended users of this guidance and training course are those individuals responsible for managing contaminated sites. Users of this training and the associated documents will develop an understanding of SRR and its importance in achieving sustainability and resilience for site remediation. Principals, best practices, resources, and trainer insights will help users conduct SRR tailored to the needs of the sites under their care.

Recommended Reading: Participants are strongly encouraged to review the ITRC Sustainable Resilient Remediation, (SRR-1) document prior to participating in the training class. Also, because SRR-1 is an expansion and update of the concepts developed in Green and Sustainable Remediation: A Practical Framework, GSR-2, review of this document is recommended but is not a prerequisite.

TPH Risk Evaluation at Petroleum-Contaminated Sites

Interstate Technology Regulatory Council Remediation at petroleum release sites is often infeasible for technical or cost reasons. Many of these sites could be depleted in typical indicator compounds, such as BTEXN, but still heavily contaminated in terms of Total Petroleum Hydrocarbons (TPH). The traditional indicator compound approach for managing petroleum contaminants may not fully identify short- and long-term potential environmental concerns, can create delays in project schedules and cost overages for sub-surface utility work or redevelopment. It is important to consider a comprehensive cumulative risk-based approach to more effectively incorporate TPH data in addition to traditional BTEXN data for cleanup and long-term management decisions.

The basis for this training course is the ITRC guidance: TPH Risk Evaluation at Petroleum-Contaminated Sites (TPHRisk-1, 2018). The guidance builds on long-standing and current research and experience, and presents the current science for evaluating TPH risk at petroleum-contaminated sites. The methods and procedures to evaluate human and ecological risk and establish cleanup requirements in the various media at petroleum release sites will assist decision makers in developing and implementing a technically defensible approach. In addition, the guidance provides information and supplemental references to assist practitioners and project managers in the assessment of fate, transport, exposure, and toxicity of TPH. The guidance users will also gain information that may be used in conjunction with classic tiered approaches for risk-based decision making (ASTM 2015b, ITRC Risk 3 2015), including modifications in the assessment and remedial-decision and regulatory framework for TPH impacts through direct comparison to screening levels, site-specific modification of screening levels, and complete site-specific risk assessment for sources, receptors, and pathways, where appropriate.

The target audience for this guidance and training course is:
  • Regulators and Program Managers interested in knowing how site management decisions can influence the TPH risk evaluation process.
  • Risk assessors new to TPH data or those who want additional knowledge and training in the current methods and common practices for collecting and using TPH data in assessments to more accurately determine human health and/or ecological risks at petroleum-contaminated sites.
  • Stakeholders who are either engaged in redevelopment at former petroleum release sites or folks who are involved in community engagement and revitalization activities.
As a participant in this training you should learn to:
  • Recognize the ITRC document as a go-to resource for evaluating TPH risk at petroleum-contaminated sites
  • Recognize how TPH -impacted media interacts with the environment and changes over time
  • Select appropriate analytic method(s) to match site objectives
  • Apply the decision framework to determine when a site-specific target level may be more appropriate than a generic screening level for TPH
Training participants are encouraged to view the associated ITRC guidance, TPH Risk Evaluation at Petroleum-Contaminated Sites (TPHRisk-1, 2018) prior to attending the class.

Strategies for Preventing and Managing Harmful Cyanobacteria Blooms

Interstate Technology Regulatory Council
The Harmful Cyanobacteria Blooms (HCBs) training reviews key information found in the ITRC Guidance Document, Strategies for Preventing and Managing Harmful Cyanobacterial Blooms.

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.

The Harmful Cyanobacteria Bloom training provides an overview of cyanobacteria and their management, covering five sections from the ITRC guidance document:
  • Introduction to the Cyanobacteria (Section 3)
  • Monitoring (Section 4)
  • Communication and Response Planning (Section 5)
  • Management and Control (Section 6)
  • Nutrient Management (Section 7)

After the five-part Strategies for Preventing and Managing Harmful Cyanobacteria Blooms training, you should understand:
  • The basic ecology and physiology of cyanobacteria, and the harmful effects they have on health, the environment, and local economies
  • Common approaches to monitoring for cyanobacteria and cyanotoxins, and how to build a monitoring program
  • The importance of good communication and coordinated response during cyanobacteria blooms, and the elements of a good response plan
  • Available options for in-lake management and control of cyanobacteria blooms
  • Nutrient management options to reduce the likelihood of cyanobacteria blooms in your water body

We encourage you to use the ITRC HCB Resources (HCB-1) and the recorded training to learn about cyanobacteria, monitoring approaches, management of active blooms, and prevention of blooms in the future. For regulators and other government agency staff, these materials present the current state of the science on cyanobacteria and approaches to manage and reduce the occurrence of blooms. We share examples and resources from across the country that can help you develop approaches of your own. While the training makes every effort to keep the information accessible to a wide audience, it is assumed that the participants will have some basic technical understanding of biology, lake management, chemistry, and environmental sciences. As with other emerging concerns, our understanding of harmful cyanobacteria blooms continues to advance. These trainings help you build cyanobacteria response plans now and point you to resources that will keep you up to date in the future.
The Training Exchange (Trainex)

The Training Exchange website (Trainex) is designed to provide a wide range of training information to EPA, other federal agency, state, tribal, and local staff involved in hazardous waste management and remediation. Trainex focuses on free training directed to federal and state staff. This site includes training schedules for deliveries of many courses, both classroom and Internet-based.

EPA works in partnership with organizations, such as the Interstate Technology Regulatory Council (ITRC), and other agencies, such as the Agency for Toxic Substances and Disease Registry (ATSDR), to offer training relevant to hazardous waste remediation, site characterization, risk assessment, emergency response, site/incident management, counter-terrorism, and the community's role in site management and cleanup.
