Contaminated Site Clean-up Information (clu-in): Internet Seminar Audio Archives

In 2023, ITRC published the Sediment Cap Chemical Isolation Guidance to supplement the 2014 Contaminated Sediments Remediation Guidance with the goal of improving consistency in sediment cap performance outcomes. Sediment capping is a commonly selected remediation approach and numerous designs have been completed. Previous cap designs have been evaluated in multiple ways, and these varying approaches have led to some differences in selection of chemical design criteria, construction tolerance specifications, and monitoring/maintenance objectives for sites with similar characteristics and contaminants, leading to different expectations for long-term performance and reliability. The ITRC Sediment Cap Chemical Isolation Guidance provides a framework for the design, construction, and long-term monitoring of the chemical isolation function of sediment caps. The framework consists of an iterative design process informed by site-specific data that balances achievement of chemical design criteria, physical design co

This webinar will include live deliveries of two presentations from the recent FRTR Fall meeting, with updated information: "Best Practices for PFAS Sampling and Evaluation" "Clean Water Act Methods: Overview of EPA's CWA PFAS Method Activities". The science and technology of site characterization for per-and polyfluoroalkyl substances (PFAS) has advanced in the five years since FRTR last addressed the topic in 2018. Federal agency budgets for PFAS remediation have grown substantially during this time. As a result, site characterization efforts such as Remedial Investigations, as well as early response actions, are underway at many Federal facilities. Funding for field-scale projects to further advance PFAS characterization technology and methodologies also has increased substantially. This webinar will allow PFAS member agencies to share results of recent and on-going PFAS projects that are improving our understanding of PFAS characterization technologies.

In response to one of the biggest emerging environmental concerns, ITRC formed the Microplastics Team in 2021 to develop the Microplastics Guidance Document. Plastics have become pervasive in modern life and are now used in a wide range of commercial and industrial applications. Microplastics may result from the degradation and fragmentation of larger plastics, or they may be intentionally produced for specific applications and products. Regardless of their origin, microplastics are now ubiquitous in our environment. Because of their small size and pervasiveness in the environment, microplastics, along with any other contaminants which are adhered to the microplastics, may be inadvertently consumed by humans and other organisms. The online ITRC Guidance Document (available in February 2023) is geared toward an audience with reasonable level of scientific understanding, but not microplastic-specific knowledge. The guidance provides a user with information on microplastics and the state of the applied scienc

Why do some states have more of their solar generation on contaminated sites, while other states are at much lower levels? This webinar will explain one of the biggest factors -- the successes of state renewable programs specifically designed for prioritizing landfills, mine sites, and other potentially contaminated lands. States such as New Jersey, Massachusetts, and Illinois have large-scale programs in place that are leading to the successful development of many megawatts of new renewable projects on RE-Powering sites per year. The state programs include financial incentives, procurement preferences, streamlined permitting, liability relief, and hands-on project development assistance designed and implemented by states over a decade or more. Drawing on its national best practice research and profiles of more than five dozen programs across more than a dozen states, EPA's RE-Powering America's Land Initiative is hosting the webinar to help you learn about common types of successful state programs, their i
