Superfund Research Program Progress in Research Webinar Part 1: Duke University and University of Arizona
08/23/2018
Internet Seminar
This Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2017. In this session, awardees from Duke University and University of Arizona will describe their research projects, accomplishments, and next steps. The Duke University SRP Center focuses on early, low-dose exposures to toxicants and developmental impacts, which are usually evident only later in life. They conduct research to characterize these outcomes following exposure to polycyclic aromatic hydrocarbons, organophosphate pesticides and flame retardants, halogenated phenolic compounds, and some metals. They are also investigating mechanisms and approaches to remove these chemicals from the environment. The University of Arizona SRP Center is addressing the risk and remediation of metal mining wastes in arid and semi-arid environments, focusing on Arizona mines as examples that can apply to other hard-rock mines around the world. Center scientists focus on finding innovative and cost-effective methods for remediating airborne and waterborne mine waste and on evaluating the effect of dusts that contain arsenic on lung development and health.

Vapor Intrusion (VI) Investigation using the Trace Atmospheric Gas Analyzer (TAGA) Mobile Laboratories
08/29/2018
Internet Seminar
Vapor intrusion has been a topic of intense interest in the United States for the recent past. The concern that the vapor intrusion pathway poses is whether an unacceptable risk exists for the occupants. To determine the risk associated with the vapor intrusion pathway, confounding factors due to the presence of these chemical from other sources need to be qualitatively and quantitatively identified so that the contributions from the vapor intrusion alone can be assessed. Because risk is compound specific and many compounds have unacceptable chronic risk levels at extremely low concentrations, an analytical technique is needed that has high selectivity and sensitivity, as well as, continuous real-time analytical updates to accurately and economically assess vapor intrusion sites. This presentation addresses a technology and practice that meets these requirements. This webinar is a result of Recommendation 9 of EPA's Superfund Task Force, which encourages the Superfund program to "utilize state-of-the-art technologies to expedite cleanup." Actions under this recommendation include expanding the use of new remediation technologies and approaches to address contaminated sites.

Superfund Research Program Progress in Research Webinar Part 2: University of Louisville, University of New Mexico, and University of Washington
09/04/2018
Internet Seminar
This Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2017. In this session, awardees from University of Louisville, University of New Mexico, and University of Washington will describe their research projects, accomplishments, and next steps. The University of Louisville SRP Center studies the cardiometabolic effects of volatile organic chemicals (VOCs) that are of high relevance to human health. Center researchers are conducting studies to unravel critical pathways of toxicity of VOCs found at Superfund and related sites. Center researchers are also creating new technologies to detect VOCs at low levels in air to enable future exposure assessment activities. The University of New Mexico Metal Exposure and Toxicity Assessment on Tribal Lands in the Southwest SRP Center (UNM METALS) focuses on risk reduction for Native Americans exposed to hazardous metals mixtures from abandoned uranium mine waste. UNM METALS emphasizes site-specific physical, mineralogic, and biogeochemical properties of the waste that alter immune function and DNA repair in tribal populations. They are also developing and testing novel cost-effective metals immobilization and removal strategies to reduce exposure risks in ways compatible with tribal culture. The University of Washington SRP Center is investigating the mechanisms and ramifications of metal neurotoxicity in humans and aquatic species. They are developing biological markers predictive of exposure, neurotoxic injury, and genetic determinants that underlie susceptibility to cadmium and manganese. They are also exploring the biogeochemical factors that govern the fate of metals, such as arsenic, in the environment.

NARPM Presents…Tools for Estimating Groundwater Contaminant Flux to Surface Water
09/05/2018
Internet Seminar
Surface water bodies adjacent to sites with contaminated groundwater may receive impacts that impair otherwise functional ecosystems and create new exposure pathways, increasing human health risks. Optimizing site characterization protocols to improve the remedy design effort is best achieved by developing knowledge of the potential extent and magnitude of contaminated groundwater discharge into the surface water body. Through field-based research, EPAs Office of Research and Development has developed several approaches to more reliably characterize system hydrology and assess contaminant flux. A series of standard methods and spreadsheet-based calculation tools have been developed to facilitate data collection and analysis, and all in an affordable and consistent manner. A case study example will be used to highlight these novel approaches to improve understanding of the spatial and temporal dynamics of contaminant transport across the groundwater-surface water transition zone.

Superfund Research Program Progress in Research Webinar Part 3: Columbia University, Massachusetts Institute of Technology, and University of Rhode Island
09/10/2018
Internet Seminar
This Superfund Research Program (SRP) Progress in Research webinar series highlights promising research from SRP Centers awarded grants in 2017. In this session, awardees from Columbia University, Massachusetts Institute of Technology, and University of Rhode Island will describe their research projects, accomplishments, and next steps. The Columbia University SRP Center conducts research that aims to understand and reduce arsenic exposure and toxicity in humans exposed to arsenic in the U.S. and Bangladesh. The projects focus on exposure to arsenic, including from private well water, potential health effects of exposure, and ways to optimize and implement remediation methods to remove arsenic from groundwater. The Massachusetts Institute of Technology SRP Center brings engineering and scientific innovation to bear on issues related to hazardous substances that are relevant to people in Maine and Massachusetts. Their research focuses on two pervasive contaminants, N-nitrosamines and polycyclic aromatic hydrocarbons, and centers around development and application of novel technologies to detect and map contaminants, and to reveal their biological effects. The University of Rhode Island Sources, Transport, Exposure and Effects of PFASs (STEEP) SRP Center is addressing the emerging and expanding problem of poly- and perfluorinated alkyl substances (PFASs) contamination. STEEP aims to better understand the pathways of PFAS contamination in groundwater, and food, and distribution to vulnerable human populations during early development. They are also supporting the development and deployment of passive sampling techniques for PFAS and their precursors in water.
