  • Audio for "Microplastics," Feb 27, 2024

    27/02/2024

    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

  • Audio for "Successful State Programs for Renewable Energy on Contaminated Sites," Feb 21, 2024

    21/02/2024

    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

  • Audio for "Recognizing the Positive Economic Impacts of Superfund Redevelopment," Feb 7, 2024

    07/02/2024

    Future use remains a key consideration for EPA's cleanup programs. EPA's Superfund program works with property owners, developers, stakeholders and communities to negotiate agreements, address barriers and make sure property uses will fit well with site remedies. In turn, the cleanup and reuse of Superfund sites revitalizes local economies, supporting jobs, new businesses, tax revenue and spending, and provides new amenities for communities affected by site contamination. EPA also works to ensure that existing businesses on properties being cleaned up under Superfund can continue operating in a way that protects human health and the environment, enabling these businesses to remain open and serve as a source of jobs and income for local communities. This webinar showcases the economic benefits of Superfund Redevelopment for communities across the country. Participants will hear about creative strategies used in redevelopment projects in New England and the Mid-Atlantic. They will also learn about collaborativ

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 ecosystem

  • Audio for "Correcting Some Misconceptions about EPA's Superfund Approach for Radiation Risk Assessment," Jan 31, 2024

    31/01/2024

    The U.S. Environmental Protection Agency (EPA) Office of Superfund Remediation and Technology Innovation (OSRTI) has primary responsibility for implementing the remedial long-term (non-emergency) portion of a key U.S. law regulating cleanup: the Comprehensive Environmental Response, Compensation and Liability Act, CERCLA, nicknamed "Superfund." The Superfund program generally addresses radioactive contamination in a consistent manner as it addresses chemical contamination, except where there are technical differences between radionuclides and other chemicals. For example, cleanup levels for radioactive contamination at sites are generally expressed in terms of risk levels (e.g., 10-4), rather than millirem or millisieverts, as a unit of measure. Although EPA and other US agencies have issued millirem-based regulations under other statutory authorities, under CERCLA EPA promulgated a risk range of 10-4 to 10-6 as a standard of protectiveness for all carcinogens including radionuclides. CERCLA guidance recomme

  • Audio for "ITRC Contaminants of Emerging Concern (CEC) Identification Framework," Jan 25, 2024

    25/01/2024

    In 2023, the ITRC Contaminants of Emerging Concern (CEC) Framework was published to help environmental regulatory agencies and other stakeholders identify, evaluate, and manage CEC's while acknowledging uncertainties in their environmental fate and transport, receptor exposure, and/or toxicity. Such an approach can be conducive to improved allocation of regulatory response resources and provide a foundation for communicating potential risk to stakeholders. The ITRC framework is comprised of a white paper and four associated fact sheets. In the white paper, CEC are defined as: "substances and microorganisms including physical, chemical, biological, or radiological materials known or anticipated in the environment, that may pose newly identified risks to human health or the environment." The framework is meant to help environmental regulatory agencies and other stakeholders by providing examples of CEC monitoring programs and guiding the user through the process of identifying CEC key characteristics, how to c

  • Audio for "Sediment Cap Chemical Isolation Training," Jan 18, 2024

    18/01/2024

    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

  • Audio for "Optimizing Injection Strategies and In situ Remediation Performance," Dec 5, 2023

    05/12/2023

    In 2020, ITRC recognized that In situ remediation technologies using amendment injections have advanced to mainstream acceptance and offer a competitive advantage over many forms of ex situ treatment of soil and groundwater. Developing a detailed site-specific strategy is absolutely critical to the success of such in situ remedies. These strategies include conducting a thorough site characterization that will allow development of a detailed Conceptual Site Model (CSM) to guide critical analysis of subsurface features and improving remediation effectiveness. In the interest of developing expedited solutions, many past in situ remediation projects have been executed based on an incomplete understanding of the hydrogeology, geology, and contaminant distribution and mass. Some of these sites have undergone multiple rounds of in situ injections but have not advanced to closure. Better strategies and minimum design standards are required to decrease uncertainty and improve remedy effectiveness. In an effort to ov

  • Audio for "1,4-Dioxane: Science, Characterization & Analysis, and Remediation," Nov 9, 2023

    09/11/2023

    In 2020, ITRC's 1,4-Dioxane team created multiple tools and documents that provide information to assist all interested stakeholders in understanding this contaminant and for making informed, educated decisions. Since the 1950s, 1,4-Dioxane has seen widespread use as a solvent stabilizer. The use of solvents through the 1980s suggests its presence at thousands of solvent sites in the US; however, it is not always a standard compound in typical analytical suites for hazardous waste sites, so it previously was overlooked. The U.S. EPA has classified 1,4-Dioxane as "likely to be carcinogenic to humans." Some states have devised health standards or regulatory guidelines for drinking water and groundwater standards; these are often sub-part per billion values. These low standards present challenges for analysis, characterization, and remediation of 1,4-Dioxane. The 1,4-Dioxane: Science, Characterization & Analysis, and Remediation training is a series of six (6) modules. The six individual modules will be presen
