    Audio for "ITRC: Reuse of Solid Mining Waste," Sep 3, 2026

    Solid mining waste represents a significant quantity of waste material in the United States and around the world. Solid mining waste has a range of physical and chemical properties that make it both potentially valuable and potentially hazardous to human health and the environment. From a commercial perspective, mining removes most of the primary minerals of interest; however, waste materials can still contain valuable minerals and other materials that can be recovered. The different types of mining sites and potential wastes for reuse provide a significant challenge but also an opportunity for innovation. Improvements in extraction and mineral processing technologies have occurred over time making it possible to recover minerals present in low concentrations. Interest in trace metals and rare earth elements (REEs) has increased, especially with the drive towards renewable energy sources increasing demand for key minerals required for solar panels and batteries. The reuse of solid mining waste can consist of reprocessing and repurposing the waste for resource recovery or a new application or product. This reuse serves as a solution to two significant needs:a domestic supply of minerals and materials for sustainable development and national defense purposesthe reclamation and remediation of land to reduce risks to human and environmental health The ITRC Reuse of Solid Mining Waste training and guidance document is geared towards state regulators and environmental consultants, mining and manufacturing stakeholders, community and tribal stakeholders, and other who have an interest in the potential reuse of solid mining waste. The guidance and this associated training course includes:Mining wastes introductionConsiderations for reusing mining waste: waste characterization, economic and market considerations, life cycle and risk assessment, regulatory considerations, & stakeholder considerationsPotential applications for the reuse of solid mining waste: examples of construction, environmental, and industrial reusesReview of technologies used in mineral beneficiation and processing Additionally, the guidance includes several case studies illustrating a range of current mining waste reuse scenarios. Prior to attending the training class, participants are encouraged to view the associated ITRC Reuse of Solid Mining Waste document.

    Audio for "SRP Progress in Research Summer 2026 Webinar Series: Session II," Jul 16, 2026

    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 Baylor College of Medicine, University of Arizona, and University of Iowa, are bringing fresh ideas and approaches to tackle complex problems related to hazardous substances. The Baylor College of Medicine (BCM) SRP Center investigates whether the maternal exposure to polycyclic aromatic hydrocarbons (PAHs) emanating from superfund sites, as well as other environmental chemicals, increases the risk of preterm births (PTBs) and augments major neonatal morbidities such as bronchopulmonary dysplasia. The BCM SRP Center wants to determine the mechanisms by which PAHs contribute to PTBs and understand the factors that could be targets for interventions to prevent and reduce the health burden associated with PAHs present in Superfund sites. The University of Arizona SRP Center works to address the unique human health risks encountered in the U.S. Southwest, a region with a rich history of metal mining and generation of mine wastes. Their overall goal is to construct a mechanistic model of how chronic exposure to mining-impacted dust that is co-contaminated with metal(loid)s and fungal spores contributes to the development of nonmalignant lung diseases. They aim to implement this model to predict exposures and associated health outcomes, to inform public health prevention in communities neighboring mine waste sites, and design remediation-based interventions to exposure. The University of Iowa SRP Center focuses its research on polychlorinated biphenyls (PCBs). The center studies PCBs in the air, particularly in schools and those emitted from contaminated soils and water of Superfund sites. Researchers examine the health impacts of inhaled PCBs, particularly on adolescents, with a focus on neurodevelopmental and metabolic effects. The University of Iowa SRP Center's long-term goal is to develop recommendations to prevent and/or limit human exposure to airborne PCBs and to improve the health and well-being of the population.

    Audio for "FY26 M2S2 Webinar: Data Usability Assessments," Jun 25, 2026

    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.
