Henry Discusses Innovative SRP Small Business Research at Water Clusters Meeting

Superfund Research Program (SRP) Health Scientist Administrator Heather Henry, Ph.D., traveled to Pittsburgh to speak at a technology transfer-focused meeting of U.S. Environmental Protection Agency (EPA) Water Technology Innovation Cluster leaders on April 27. The full-day meeting focused on how water clusters can support early-stage water companies’ efforts to find funding.

The EPA Environmental Technology Clusters Program supports regional groupings of businesses, government, research institutions, and other organizations focused on innovative technologies for clean water. Led by Sally Gutierrez and Maggie Theroux of the EPA Office of Research and Development, these dense networks can help solve the nation's environmental challenges by spurring technology innovation.

At the meeting, about 60 people, primarily the heads of local and regional Water Clusters, focused on federal funding in water. Henry, as well as other program staff for top Federal Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs, attended the meeting to highlight their federal grant programs and accomplishments. Henry highlighted innovative water, drinking water remediation and detection technologies coming out of the NIEHS SRP SBIR/STTR program.

The meeting also featured a panel discussion for SBIR/STTR Program Managers, including Henry, April Richards (EPA); Ali Mohamed, Ph.D., (National Institute of Food and Agriculture); Prakash Balan, Ph.D., (National Science Foundation); and Manny Oliver, PhD (U.S. Department of Energy). Each of the program staff described their SBIR and STTR programs that promote commercialization of water technology, the process of applying for SBIR/STTR grants, and provided information on keys to a successful proposal.

Superfund Research Program (SRP) grantee Daniel Schlenk, Ph.D, presented work related to aquatic ecotoxicology as part of the Duke University SRP seminar series on May 7. A professor at the University of California, Riverside, Schlenk’s research focuses on understanding the biochemical factors that influence susceptibility to environmental and natural chemicals. During his presentation, he discussed his work on the critical windows of susceptibility and mechanisms of selenium toxicity in fish.

Selenium is an essential micronutrient that can cause embryo toxicity at levels 7 to 30 times above essential concentrations. Schlenk and his research team are working to better understand the effects of selenium during critical windows of development and how other factor, such as salinity, affect developmental toxicity of selenium.

Schlenk also co-leads Exploring the Importance of Aging in Contaminant Bioavailability and Remediation, an SRP-funded individual research project. An often-neglected fact is that contamination at most Superfund sites is a result of historical events, and that contaminants at these sites have resided in the same media for many years or decades, a biogeochemical process loosely termed aging. As part of his SRP-funded grant, Schlenk and Jay Gan are developing a simple method for measuring and accounting for contaminant aging in risk assessments and remediation. They will apply the method to sediment samples collected from the Palos Verdes Shelf Superfund site off the Los Angeles coast. Sediments at this site contain high levels (up to 200 mg/kg) of dichlorodiphenyltrichloroethane (DDT) and polychlorinated biphenyls (PCBs) deposited from as far back as 60 years ago.

On April 23, Duke University Superfund Research Program (Duke SRP) Center researcher Joel Meyer, Ph.D., and Duke SRP Research Translation Core coordinator Gretchen Kroeger took a trip down to the U.S. Centers for Disease Control and Prevention Agency for Toxic Substances and Disease Registry (ATSDR) campus outside of Atlanta to provide information about Duke SRP Center research and foster collaborations between Duke SRP and ATSDR.

Meyer, whose research at Duke University focuses on the role of mitochondria as a target of toxicity for a variety of contaminants, gave a presentation highlighting Duke SRP Center work with polycyclic aromatic hydrocarbons (PAHs) along Virginia’s Elizabeth River. He discussed his research related to mitochondrial DNA damage and the later life effects of environmental exposures.

After the presentation, Meyer and Kroeger met with several groups of ATSDR scientists to discuss their research and community-engaged work with exposed populations. Meyer and Kroeger returned to Duke with a better understanding of the great work being done at ATSDR, as well as an assortment of research ideas, connections, and hope for future collaborations with the Agency.

Northeastern University Superfund Research Program (Northeastern SRP) Center trainee Kelly Ferguson, Ph.D., is going beyond her research by bringing her work to stakeholders and learning about environmental decision making. Ferguson, a postdoctoral research fellow at the University of Michigan, focuses on exposure assessment and molecular epidemiology with the Puerto Rico Testsite for Exploring Contamination Threats (PROTECT) Program.

On April 29, Ferguson gave a talk at the 8th Copenhagen Workshop on Endocrine Disrupters. Her talk, “Developmental effects of phthalates: what are the mechanisms?,” introduced the PROTECT cohort and summarized preliminary findings on the relationship between maternal phthalate exposure during pregnancy and changes in hormone, inflammation, and oxidative stress levels.

This past year, Ferguson participated in the Reach the Decision Makers Fellowship, part of the University of California, San Francisco Program on Reproductive Health and the Environment. This fellowship trains scientists, community members, clinicians, and public health professionals to effectively promote science and health-based policies at the U.S. Environmental Protection Agency (EPA).

As the culmination of this fellowship, Ferguson and the Detroit Reproductive Advocacy Matters (DREAM) team traveled to Washington, D.C., to meet with key policy makers at the EPA. Following the release of the proposed National Ambient Air Quality Standards rule on ozone, the group submitted comments advocating for the inclusion of pregnant women and communities with multiple risk factors as vulnerable populations. While in D.C., the group met with Janet McCabe, J.D., acting assistant administrator of the EPA Office of Air and Radiation, and Thomas Burke, Ph.D., deputy assistant administrator of the EPA Office of Research and Development, to discuss these comments and push for inclusion of these populations in future risk assessment processes.

Superfund Research Program (SRP) grantee Upal Ghosh, Ph.D., and his research team received two 2015 Excellence in Environmental Engineering and Science awards for the development and application of innovative remediation technologies. Ghosh, a professor at the University of Maryland, Baltimore County, was recognized by the American Academy of Environmental Engineers and Scientists at its conference on April 23.

Ghosh received the 2015 Honor Award – University Research for developing a method for in situ remediation of contaminated sediments with activated carbon, and translating that method into practice. This work was part of Ghosh’s previous SRP Individual Research Project, which led to the technology transfer efforts. Hilda Khoei and Eli Patmont, graduate students working with Ghosh, were also recognized for their efforts as part of the project.

According to the award profile, Ghosh’s research has been successful in transitioning fundamental understanding of pollutant bioavailability into an innovative application for sediment remediation. In situ remediation with activated carbon amendment provides several advantages over traditional remediation methods, including less disruption to habitats in sensitive rivers and wetlands, amenability to shallow or constricted locations, and potential for much lower cost.

Ghosh also collaborated on a project to remediate Mirror Lake in Delaware using activated carbon, which won a 2015 Honor Award – Small Projects. Richard Greene, Ph.D., an environmental engineer with the Delaware Department of Natural Resources and Environmental Control, worked with Ghosh to use activated carbon to sequester contaminants in the lake sediments, thereby interrupting the transfer of PCBs from the sediments to the water column and fish.
