Contaminated Site Clean-Up Information (CLU-IN): Internet Seminar Audio Archives Contaminated Site Clean-Up Information (CLU-IN)

This training class builds on the earlier information for treatment technologies presented in the PFAS 101 CLU-IN training. It provides more in-depth information regarding considerations for implementing integrated PFAS treatment technologies and remediation strategies. This training introduces the concept that achieving site remedial objectives will likely necessitate the implementation of multiple treatment technologies and remediation strategies (i.e., an integrated remedial strategy). Specifically, this training uses a hypothetical conceptual site model to frame the discussion of remedial approaches for PFAS impacted source area soil, source area groundwater, and more dilute groundwater plumes. The training concludes with a discussion of select field implemented and developing disposal and destructive technologies for managing treatment residuals.

Resources and further details for the topics included in this training are in the published PFAS-1 guidance document in Sections 12 and 15 along with referenced tables.

Learning Objectives:
What types of media, sources, and pathways might require intervention and treatment?How are field-implemented PFAS remediation technologies commonly applied?What developing technologies show promise for PFAS treatment?How may integrated remedial strategies be applied?What are the key considerations for applying field implemented and developing technologies?

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.The instructional methodology for this course includes lecture, group discussions, case studies, and quizzes. The target audience for this course is federal, state, and tribal representatives who work on Federal Facility cleanups. This course is part of the Federal Facilities Academy training program. Please consider registering for other Federal Facility Academy courses and obtain a certificate upon completion of the entire Federal Facility Academy series (12 courses total).

U.S. Environmental Protection Agency (EPA) and its contractors performing oversight at Superfund Sites review numerical models developed to simulate contaminant transport. An analytical transport model could be used to check the numerical model results but a practical modeling tool based on a 3D analytical solute transport model is not publicly or commercially available. The roles of an analytical model in Superfund oversight are to simulate the general plume behavior; guide the development of, and provide a check for, a more complex numerical solute transport model; and evaluate smaller scale transport such as during natural gradient tracer tests. EPA tasked APTIM to develop an analytical model for solute transport in a three-dimensional aquifer of finite thickness with uniform flow, dual porosity, sorption, sequential decay, and time-dependent source. The new model was verified against existing analytical models for special cases and against numerical models MT3DMS and RT3D, and published in two journal papers. EPA tasked RTI to develop a graphical user interface (GUI) for the model. Example applications are analysis of tracer tests at the Stringfellow Superfund Site and simulation of TCE plume at the Fresno Sanitary Landfill.

This webinar will be focused on MR-QAPP Toolkit, Module 2 - Remedial Actions that was published in March 2023. Presentations will cover Worksheet 11 and how Data Quality Objectives (DQOs) are presented in this new toolkit as well as the new Measurement Performance Criteria (MPCs) and Measurement Quality Objectives (MQOs). There will also be a discussion of managing data deliverables using Delivery Units and Survey Units, and the related Data Usability Assessments (DUAs). Presentations will be suitable for the varied M2S2 webinar audience, which typically includes government, regulator, and contractor attendees, and there will be opportunities for questions and discussion.

The ITRC Managed Aquifer Recharge (MAR-1) Training is intended for state regulators and stakeholders who may not be familiar with the opportunities and challenges associated with MAR. It provides a basic understanding of MAR concepts, along with case studies, that showcase examples of successful MAR applications. For those who are familiar with MAR, the training gives an overview of the components of the MAR process along with the important considerations associated with each component necessary for the design and implementation of a MAR project. It is important to understand that MAR is an area of active research and expanding practical applications, and that this management process is continuing to evolve with time.The combination of climate change and growing demand for fresh water has resulted in an increase in the vulnerability and scarcity of freshwater supplies around the world. The need for fresh water to grow crops and provide for the welfare of the general population, economic growth, and ecosystems is becoming more acute. In the past 50 years, the amount of water withdrawn for human use has tripled. MAR is becoming an increasingly important method for improving and supplementing subsurface freshwater storage and ecosystems with an additional benefit of reducing flood risk, managing stormwater, mitigating subsidence, and controlling saltwater intrusion. Training ObjectivesUnderstand MAR and its applications.Recognize MAR as a process rather than a single technology. Acknowledge that MAR can be widely applied.Understand MAR's role in the future for addressing water supply resilience and climate impacts.Training GoalsProvide a model of the MAR process illustrating the primary components and their interaction.Provide an overview of the applications of MAR and the role in addressing climate change impacts through sustainability and resilience in water resources management.Provide information on each component of MAR and the critical considerations for each component in the design of a MAR project.Reference case studies illustrating the various applications of MAR.After the MAR Training, the audience will have the tools necessary to understand MAR and how it can be used as a water resource management tool that encompasses a wide variety of water sources, recharge methods, and storage management practices. The audience will develop an understanding of MAR and its importance in achieving sustainability, resilience, and the far-reaching benefits of MAR related to water supply and quality, mitigation of saltwater intrusion, flood control, and ecological habitats. This training will provide information about the components of a MAR project to help regulators, practitioners, and stakeholders in the development and review of a MAR project.Recommended Reading: Participants are strongly encouraged to review the ITRC Managed Aquifer Recharge document prior to participating in the training class.

This training class builds on the earlier information for fate and transport and site characterization presented in the PFAS 101 CLU-IN training. It provides more in-depth information for fate and transport, site characterization, source identification and some introductory information on environmental forensics. These topics will be presented along with options and a framework for data visualization. This training will focus largely on PFAS fate and transport in groundwater. The goal is to provide detailed information about the inputs practitioners can use to develop a robust conceptual site model to help understand fate and transport at PFAS sites, and how to gather evidence of multiple sources.

Resources and further details for the topics included in this training are in the ITRC Guidance Document (PFAS-1) in Sections 2.6, 3, 4, 5, 10, 11 and 15 along with referenced tables.

Learning Objectives:
Understand fate and transport processes that are unique to PFAS due to their physical and chemical properties.How to characterize sites with these processes and properties in mind.Describe options for and advantages of various data visualization techniques.Introduce basic forensic techniques for source evaluation.
