The Data Usability Assessment (DUA) is a defined process that considers whether data meet project data quality objectives (DQOs) as they relate to the decision to be made and evaluates whether data are suitable for making that decision. DUAs are critical to ensuring that Munitions and Explosives of Concern (MEC) and munitions constituents (MC) data are of the right type, quantity, and quality to meet project DQOs. The project-specific requirements for conducting the DUA process are defined during the Systematic Planning Process and documented in the project-specific QAPP. This webinar will discuss the DUA process for both MEC and MC during remedial investigation and remedial actions. At the end of this webinar, attendees will be able to explain the purpose of DUA, identify the project team members required to participate, select the appropriate inputs, conduct the assessment, and document the DUA outputs. 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.

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).

The Interstate Technology & Regulatory Council (ITRC) is presenting a training on the basics of per- and polyfluoroalkyl substances (PFAS) chemistry. This training supplements the ITRC PFAS Introductory training and ITRC Beyond the Basics Training sessions.  You can find ITRC PFAS training resources online at https://pfas-1.itrcweb.org/pfas-training/.

PFAS are an emerging group of contaminants that present unique challenges in many areas including: widespread use and presence in the environment, sampling and analysis, fate and transport, and remedial approaches. This training session will provide PFAS practitioners with an understanding of the unique aspects of PFAS chemistry that guide fate and transport, treatment, regulations, and decision-making on PFAS sites.   
Key focus areas of the training include the following:Why are PFAS different from other organic chemicals?How are PFAS defined?How are PFAS manufactured and why does that matter?What are the differences between perfluoroalkyl and polyfluoroalkyl substances?What are the naming conventions used for the different types of PFAS?How are short-chain and long-chain perfluoroalkyl acids (PFAAs) defined?What are precursors and why are they important?What are some of the unique chemical properties of PFAS and why do they matter?Resources and further details included in this training are in the  ITRC Guidance Document (PFAS-1).

The Superfund Research Program (SRP) is holding a webinar to provide information about the continuation of the Superfund Hazardous Substance Research and Training Program (P42). The Notice of Funding Opportunity (NOFO), RFA-ES-27-004, calls for applications to establish P42 Centers, which support problem-based, solution-oriented research relevant to Superfund. The Centers consist of multiple integrated projects representing both the biomedical and environmental science disciplines. Center cores are also tasked with administrative (that includes Center’s leadership, data management and analysis, and training functions) and translational research and engagement, and as applicable, research support functions. The next application due date is September 25, 2026 (5:00 PM local time of applicant organization).

On the webinar, NIEHS staff will provide information and answer questions about the P42 request for application (RFA) to address the broad, complex health and environmental issues that arise from the multimedia nature of hazardous waste sites.

This Progress in Research webinar series, hosted by the National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP), showcases research from 6 schools funded by SRP in 2025. These awards were made as part of the P42 grant solicitation RFA-ES-20-014. In the two-part series, awardees will highlight their research projects, accomplishments, and next steps. The newly funded centers, including Oregon State University, University of North Carolina-Chapel Hill, and University of Southern California, are bringing fresh ideas and approaches to tackle complex problems related to hazardous substances.

The Oregon State University (OSU) SRP Center is driven to identify polycyclic aromatic hydrocarbons (PAHs) in the environment, to characterize their toxicity, and to specify the environmental concentrations at which they pose no threat to human health. The OSU SRP Center studies the composition of complex PAH mixtures, the changes in composition after remediation and natural attenuation, and the implications of PAH mixtures for human health.

The University of North Carolina (UNC)-Chapel Hill SRP Center addresses serious public health challenges faced by communities in North Carolina and across the nation related to inorganic arsenic (iAs). The UNC-Chapel Hill SRP Center is working to identify these factors that would facilitate the development of novel solutions/interventions to reduce the prevalence of iAs-associated diabetes, as well as other diseases associated with iAs exposure.

The University of Southern California (USC) SRP Center works to develop problem-based, solution-oriented scientific knowledge and innovative technologies to address the issue of poly- and perfluoroalkyl substances (PFAS) water contamination in Superfund and other sites. The USC SRP Center has the goal of specifically addressing PFAS in relation to their effects on liver disease and addressing urgent concerns regarding water quality and human health in populations affected by PFAS exposures and Superfund sites.
