The Society of American Military Engineers (SAME) Denver Post and Philadelphia Post along with the US Environmental Protection Agency (EPA) are hosting a series of webinars based on talks given at recent Design and Construction Issues at Hazardous Waste Sites (DCHWS) Symposiums. The mission of the DCHWS symposiums is to facilitate an interactive engagement between professionals from government and the private sector related to relevant and topical issues affecting applications of engineering and science associated with cleaning up hazardous waste sites. The symposiums also serve as a platform to facilitate the exchange of information, encourage dialogue, share experiences, and build and enhance communication among design and construction professionals.

The role sustainability and resiliency play in a cleanup project is dependent upon site-specific physical characteristics and stakeholder concerns. However, the overlying framework to evaluate and implement sustainable resilient remediation practices is applicable to all site types. This technical presentation will start with an overview of the sustainable resilient remediation framework, and recent guidance updates and initiatives. Followed by four case studies that highlight integration of resiliency and sustainability at various phases of the project life cycle:

• Case Study #1: Combining Green and Sustainable Remediation (GSR) Evaluations with Cost/Risk Analysis as Effective Communication Tools to Drive Cleanup Decisions
• Case Study #2: GSR to Inform Technology Feasibility Assessment & Incorporating Climate Change into Remedial Design and Performance Monitoring
• Case Study #3: Development of Resiliency Remedial Design Guides for a Sediment Site Informed by Stakeholder Engagement at Remedial Action Workshops
• Case Study #4: Hydrodynamic Modeling to Support Remedial Design Utilizing EPA's Stormwater Management Model (SWMM) Climate Adjustment Tool (CAT)

Opportunities to ask questions will be interwoven throughout the presentation. The presentation will end with lessons learned from other cleanup project experience, followed by Q&A.

The target audience for this technical presentation includes environmental regulators at all levels of government, private and public responsible or obligated parties (Ops), current site owners and operators, environmental consultants, and prospective purchasers of property and their agents. Other stakeholders who have an interest in a property can also use this guidance to help understand how sustainable resilient remediation practices can be applied.

Interested in creative site redevelopment strategies from an experienced developer? The Naval Industrial Reserve Ordnance Plant and FMC Corp. Superfund sites designed and manufactured advanced naval weapons. The developer has built a business industrial park in four phases. Hyde Development worked with Minnesota's environmental agency to enroll the property encompassing the site in the state's Voluntary Investigation and Cleanup Program. Using this alternative cleanup mechanism enabled close coordination between the cleanup and development design stages to support a phased cleanup approach that would allow for phased redevelopment construction. Part of Superfund Redevelopment's roundtable webinar series, this training will focus on opportunities, benefits, strategies, liability protections and risk management for partnerships between developers, and local and state governments. This interactive session will include robust Q&A as well as an opportunity for participants to share their perspectives on how to encourage more and faster Superfund site redevelopment across the country. Presenters will answer questions about available resources and support, share best practices and update participants on the latest tools and guidance.

The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on exposures and latent disease risk. The series will feature SRP grantees and colleagues who are studying how we can better understand the health effects of exposures when there is a long latency period between the exposure and the onset of the disease.

The first session will provide an introduction to exposures and latent disease risk, including information about windows of susceptibility, later-life health outcomes, and will set the stage for the other sessions.

Risk-based cleanup goals are often calculated assuming that chemicals present in soil are absorbed by humans as efficiently as the chemicals dosed during the toxicity tests used to determine regulatory toxicity values (such as the Reference Dose or Cancer Slope Factor). This assumption can result in inaccurate exposure estimates and associated risks for some contaminated sites because the amount of a chemical absorbed (the chemical's bioavailability) from contaminated soil can be a fraction of the total amount present. Properly accounting for soil-chemical interactions on the bioavailability of chemicals from soil can lead to more accurate estimates of exposures to soil contaminants and improve risk assessments by decreasing uncertainty.
The basis for this training course is the ITRC guidance: Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1). This guidance describes the general concepts of the bioavailability of contaminants in soil, reviews the state of the science, and discusses how to incorporate bioavailability into the human health risk assessment process. This guidance addresses lead, arsenic, and polycyclic aromatic hydrocarbons (PAHs) because evaluating bioavailability is better understood for these chemicals than for others, particularly for the incidental ingestion of soil.
The target audience for this guidance and training course are:

• Project managers interested in decreasing uncertainty in the risk assessment which may lead to reduced remedial action costs.
  
• Risk assessors new to bioavailability or those who want additional confidence and training in the current methods and common practices for using bioavailability assessment to more accurately determine human health risk at a contaminated site.

• Value the ITRC document as a "go-to" resource for soil bioavailability
  
• Apply the decision process to determine when a site-specific bioavailability assessment may be appropriate
  
• Use the ITRC Review Checklist to develop or review a risk assessment that includes soil bioavailability
  
• Consider factors that affect arsenic, lead and PAH bioavailability
  
• Select appropriate methods to evaluate soil bioavailability
  
• Use tools to develop site-specific soil bioavailability estimates and incorporate them into human health risk assessment

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)

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.

At some sites, complex site-specific conditions make it difficult to fully remediate environmental contamination. Both technical and nontechnical challenges can impede remediation and may prevent a site from achieving federal- and state-mandated regulatory cleanup goals within a reasonable time frame. For example, technical challenges may include geologic, hydrogeologic, geochemical, and contaminant-related conditions as well as large-scale or surface conditions. In addition, nontechnical challenges may also play a role such as managing changes that occur over long time frames, overlapping regulatory and financial responsibilities between agencies, setting achievable site objectives, maintaining effective institutional controls, redevelopment and changes in land use, and funding considerations.
This training course and associated ITRC guidance: Remediation Management of Complex Sites (RMCS-1, 2017), provide a recommended holistic process for management of challenging sites, termed "adaptive site management." This process is a comprehensive, flexible, and iterative process that is well-suited for sites where there is significant uncertainty in remedy performance predictions. Adaptive site management includes the establishment of interim objectives and long-term site objectives that consider both technical and nontechnical challenges. Periodic adjustment of the remedial approach may involve multiple technologies at any one time and changes in technologies over time. Comprehensive planning and scheduled evaluations of remedy performance help decision makers track remedy progress and improve the timeliness of remedy optimization, reevaluations, or transition to other technologies/contingency actions.
By participating in this training course we expect you will learn to apply the ITRC guidance document to:

• Identify and integrate technical and nontechnical challenges into a holistic approach to remediation
  
• Use the Remediation Potential Assessment to identify whether adaptive site management is warranted due to site complexity
  
• Understand and apply adaptive site management principles
  
• Develop a long-term performance-based action plan
  
• Apply well-demonstrated techniques for effective stakeholder engagement
  
• Access additional resources, tools, and case studies most relevant for complex sites
  
• Communicate the value of the guidance to regulators, practitioners, community members, and others

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.

• 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
