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

Petroleum is a complex mixture of many compounds. Regulatory and technical guidance documents commonly focus on the hydrocarbon components of that mixture, or perceived risks that they present. However, focusing on a specific area of concern often causes practitioners to overlook other aspects of a release. For example, concerns related to exposure to total petroleum hydrocarbons (TPH) risks may be overlooked while pursuing concerns related to light non-aqueous phase liquid (LNAPL) recovery or petroleum vapor intrusion (PVI). This class is designed to provide a basic overview of hydrocarbon behavior in the subsurface and how to scientifically assess concerns arising from the release of petroleum products into the environment. It will highlight key issues that help identify and manage TPH, LNAPL, and PVI risks together. Key concepts will include: Fundamentals of petroleum hydrocarbonsPetroleum chemistryHow TPH, LNAPL, and PVI are relatedBuilding an integrated conceptual site model (CSM) What is a CSM…

Tracking Restoration And Closure (TRAC) is a web-based application that combines infographics, annual statistics, and historical facts to clearly communicate the current status of groundwater contamination cleanup efforts at Department of Energy Office of Environmental Management (DOE-EM) sites across the nation.  TRAC is a tool to share information about and provide transparency into environmental remediation progress at these cleanup sites.  With TRAC, users can explore robust and consistent geospatial visualization of contaminants of concern above the regulatory cleanup concentrations at three levels of detail:  EM complex, EM site, and waste management unit.  Each level includes narrative information on key topics, such as cleanup challenges/priorities and technology approaches, and metrics about contaminant plumes, regulatory context/status, and remedy technologies/implementation status.

The NIEHS Superfund Research Program (SRP) is hosting a Risk e-Learning webinar series focused on using artificial intelligence (AI) and machine learning to advance environmental health research. The series will feature SRP-funded researchers, collaborators, and other subject-matter experts who aim to better understand and address environmental health issues by applying AI and machine learning approaches to complex issues. Recent advances in AI and machine learning methods show promise to improve the accuracy and efficiency of environmental health research. Over the course of three sessions, presenters will discuss how they use AI and machine learning approaches to improve chemical analysis, characterize chemical risk, understand microbial ecosystems, develop technologies for contaminant removal, and more. In the third and final session, ML & AI Applications to Understand Omics, Metabolomics, & Immunotoxicity and Optimize Bioengineering Using Datasets, Models, and Mass Spectrometry, speakers will discuss h

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

Groundwater Policy and Federal Facilities Overview is a two-hour webinar course that provides an overview of U.S Environmental Protection Agency (EPA) groundwater policies and guidance with emphasis on cleanups at federal facilities. By taking this course, participants will achieve the following objectives:Identify EPA groundwater policies;Understand groundwater classification and beneficial use in restoration objectives;Understand nature and extent considerations from groundwater contaminant plumes;Explore applicable or relevant and appropriate requirements (ARARs) commonly associated with groundwater remedies;Identify groundwater considerations for monitored natural attenuation (MNA), institutional controls, and technical impracticability waivers; and,Discover information on major groundwater policies from other federal agencies, such as Department of Defense (DoD) and Department of Energy (DoE).The instructional methodology for this course includes lecture and quizzes. The target audience for this course

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 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 science without having to go to the
