Seminars Sponsored by the Interstate Technology and Regulatory Council
Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment

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
1:00PM-3:15PM EDT

Characterization and Remediation of Fractured Rock

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.
Training participants are encouraged to view the associated ITRC guidance, Characterization and Remediation of Fractured Rock prior to attending the class.
1:00PM-3:15PM EDT
17:00-19:15 GMT

Geospatial Analysis for Optimization at Environmental Sites

The purpose of ITRC's Geospatial Analysis for Optimization at Environmental Sites (GRO-1) guidance document and this associated training is to explain, educate, and train state regulators and other practitioners in understanding and using geospatial analyses to evaluate optimization opportunities at environmental sites. With the ITRC GRO-1 web-based guidance document and this associated training class, project managers will be able to:
- Evaluate available data and site needs to determine if geospatial analyses are appropriate for a given site
- For a project and specific lifecycle stage, identify optimization questions where geospatial methods can contribution to better decision making
- For a project and optimization question(s), select appropriate geospatial method(s) and software using the geospatial analysis work flow, tables and flow charts in the guidance document
- With geospatial analyses results (note: some geospatial analyses may be performed by the project manager, but many geospatial analyses will be performed by technical experts), explain what the results mean and appropriately apply in decision making
- Use the project manager’s tool box, interactive flow charts for choosing geospatial methods and review checklist to use geospatial analyses confidently in decision making
1:00PM-3:15PM EDT
17:00-19:15 GMT

Connecting the Science to Managing LNAPL Sites a 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)
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)
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
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
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.

Remediation Management of Complex Sites

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
Case studies are used to describe real-world applications of remediation and remediation management at complex sites. Training participants are encouraged to view the associated ITRC guidance Remediation Management of Complex Sites (RMCS-1, 2017) prior to attending the class.
