Given the COVID-19 national health emergency and its affects on corporate/government travel policies as well as local/state health requirements, it has become necessary to hold the conference as a remote webinar based event. With the DCHWS Philadelphia Conference being canceled earlier this year, our fall conference will be co-sponsored by the SAME Philadelphia Post, the SAME Denver Metro Post, and the U.S. Environmental Protection Agency.

Registration for this session closed on October 22. For more information on this session, please visit the sponsor's event website.

The NIEHS Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2020. In this session, awardees from Harvard School of Public Health, University of North Carolina-Chapel Hill, and University of Arizona will describe their research projects, accomplishments, and next steps.

The Harvard School of Public Health Center, "Metals and Metal Mixtures: Cognitive Aging, Remediation, and Exposure Sources (MEMCARE)," focuses on understanding the effects of exposure to heavy metals (Pb, As, Mn, Cd, Cr, and Se) and metal mixtures on late-life cognitive health. Center scientists also conduct research on remediation strategies for these exposures to reduce the risk of cognitive decline and memory loss in older populations.

The University of North Carolina-Chapel Hill SRP Center works to address public health challenges related to inorganic arsenic (iAs) contamination of private drinking water wells. Their research explores the biological mechanisms and susceptibility factors underlying diseases associated with iAs exposure, with a focus on diabetes. They also investigate methods for predicting well water contamination by arsenic and other toxic metals, along with removal strategies. Center scientists hope to develop interventions to reduce the prevalence of iAs-associated diabetes and other diseases.

The University of Arizona SRP Center, "Exposures, Health Impacts, and Risk for Mine Waste Contamination," is addressing the unique human health risks encountered in the U.S. Southwest, where distinct geologic and climatic attributes affect human health and exposures to a variety of toxicants, especially arsenic. Arsenic exposure has been linked to the development of diabetes which is especially prevalent in vulnerable populations residing near metal-mining sites. Center scientists are investigating how chronic exposure to arsenic-containing mine waste contributes to the development of diabetes and how exposure can be prevented through a combination of innovations related to the characterization of legacy mine sites and remediation strategies, data science interoperability, and community-engaged health promotion.

This webinar will provide an overview of the brownfield market in the post-COVID era and the opportunities and constraints brought on by the pandemic. We will look at the US real estate market across all market sectors and how these market sectors have responded both good and bad to the pandemic. This analysis will then be followed a brief discussion of the global impacts of the pandemic as it relates to supply chain resiliency and new US initiatives for reduced reliance of foreign suppliers and manufacturers that will drive reshoring and nearshoring initiatives, both of which will positively impact the US real estate market and economy, including demand for strategically located brownfield sites that will fill the need for this growth. Finally, we will tie all this information together to give the audience thoughts on opportunities for brownfield redevelopment in your community and how communities can prepare now to eliminate encumbrances and stigma traditionally associated with brownfields and reposition these sites for redevelopment opportunity in the post-COVID era.

Sea level rise could cause frequent or even permanent flooding of coastal brownfield sites, their access roads, or other critical services. These floodwaters can release and spread site contaminants and debris, endangering the health of the local people and other living things. Brownfield site managers, project staff, and property owners can manage sea level rise risk and uncertainty with preventive measures, thus reducing the cumulative costs and increasing management and reuse options.

This webinar will introduce brownfield and land revitalization project staff and OLEM and other colleagues to simple tools to understand how sea level rise can impact a coastal site. This session will introduce you to steps to screen for and reduce sea level rise risks, and walk through a case study application in Philadelphia, PA.

The Superfund Research Program (SRP) is holding a webinar to provide information about the new "Superfund Hazardous Substance Research and Training Program (P42)" funding opportunity, RFA-ES-20-014. The RFA was released on September 2, 2020, and the application deadline is February 15, 2021.

On the webinar, NIEHS staff will provide information and answer questions about the P42 RFA to address the broad, complex health and environmental issues that arise from the multimedia nature of hazardous waste sites. SRP Center grants support problem-based, solution-oriented research Centers that consist of multiple, integrated projects representing both the biomedical and environmental science disciplines. The Center cores are tasked with administrative (which includes research translation), data management and analysis, community engagement, research experience and training coordination, and research support functions.

The webinar will also focus on changes from previous solicitations. For more information about the RFA, see the SRP Funding Opportunities - Multiproject Center Grants page.

Interested in creative site redevelopment strategies from an experienced developer? During this webinar, Michael Goldstein, a pioneer in contaminated property redevelopment, will share why he thinks there is such intense interest in Superfund site redevelopment. From his vast experience and accomplishments as a Brownfield and Superfund site developer, attorney, and fund manager, he will discuss his views on the future market trends, collaboration with EPA and investment opportunities for Superfund redevelopment. The webinar will also provide real-life lessons learned and tips for private developers and local governments seeking to redevelop Superfund sites.

Hard rock mining results in extensive land disturbance due to economic mineral extraction and residual mine waste deposition. Revegetation accelerates reclamation of land disturbed by mining; however, the revegetation of mine waste sites in arid regions of the world has unique environmental challenges due to low water availability and sensitive ecologies. Further complicating the issue is the myriad of wastes that exist. Here we focus on mine tailings, which exhibit a wide range of pH and metal content, as well as waste rock. In this presentation, we will discuss what we have learned over the last decade about how below-ground metrics are related to and can predict revegetation success under a variety of conditions and revegetation approaches. We will present data from legacy and modern waste sites examining both direct planting into mine waste and cap and plant scenarios. We are using these data to identify below-ground metrics that correlate with vegetation establishment patterns and are easy to measure; and then using the identified metrics to develop guidance for prediction of tipping points for vegetation success or failure. An additional outcome of this work is creation of the University of Arizona Center for Environmentally Sustainable Mining which has facilitated a partnership with Arizona copper companies called the Collaborative Industry-University Research Initiative on Revegetation of Mine Wastes. This partnership has enabled both a comprehensive assessment of multiple revegetation strategies under diverse conditions and an open atmosphere wherein results are shared among all partners through annual reports and meetings To view this archive online or download the slides associated with this seminar, please visit http://www.clu-in.org/conf/tio/mining-reveg_081220/
