Assessment of a Passive Sampler for Aquifer Microbial Community Profiling and Comparison of Porous Media
Riddley, Mia Raye (Virginia Tech, 2025-07-14)
Managed aquifer recharge (MAR) with advanced treated wastewater is a promising strategy to combat aquifer depletion; however, its impact on native microbial communities remains insufficiently characterized. Concerns include the potential introduction of pathogens, antibiotic resistance genes (ARGs), and trace organic pollutants, as well as the disruption of native microbial processes critical for contaminant degradation in groundwater. However, it is very challenging to sample aquifer microbes in situ, especially in a representative, time-resolved fashion. With this goal, we developed a passive sampler that employs removable cartridges containing solid media designed to re-create the aquifer environment in a controlled fashion and support consistent, repeatable, time-series sampling. A bench-scale, continuous-loop study compared microbial community dynamics across three candidate porous media: native aquifer sediment, zirconia beads, and laboratory-grade silica sand. 16S rRNA gene amplicon sequencing was applied to profile microbial communities and revealed that native aquifer sediment from the aquifer of study best reflected influent microbial composition and temporal shifts, particularly among the dominant bacterial phyla Proteobacteria, Bacteroidota, Planctomycetota, and Verrucomicrobiota. Native sediment also exhibited more spatial consistency in microbial diversity. Based on these findings, a full-scale, 3Dprinted sampler using native sediment was developed for long-term monitoring in MAR systems to support future study of the impacts of introduction of advanced treated water into an aquifer.
Ode from Oman: Student paintings from VT Arabic Abroad
Fralin, Scott; Caesar, Anna; Nasseriddine, Ragheda (Virginia Tech, 2024-09-19)
This exhibit showcases the paintings of Anna Caesar who, while in Oman studying Arabic and immersing herself in Arabic culture, reflected on her experience through painting. These paintings depict Oman and the study abroad experience in a very personal and unique light.
2023-2024 Study Abroad Photo Contest Finalists
Fralin, Scott; Schoener, Lauren; Perezous, Janika; Lucier, Emma; Le, Jessica (Virginia Tech, 2024-11-11)
These photos, taken by Virginia Tech students and faculty, depict study abroad experiences during the 2023-2024 academic year. The photos represent the four finalists in each of the five categories: Hokies Go Global, The Heart of It, Postcards of the World, Cultural Connections, and Living Textbook (faculty & staff submissions).
thương
Fralin, Scott; Ha, Nina (Virginia Tech, 2025-02-28)
The exhibition, thương features video and photography by Việt Lê and Ly Hoàng Ly, two Vietnamese Diasporic artists. Ly is a multidisciplinary artist working across poetry, painting, video, performance art, artist’s book, installation and public art. Việt's creative and critical practice as a queer, disabled artist focuses on sexualities, spiritualities–the physical and the metaphysical. Ly and Việt’s residency and exhibition is supported by the Beyond Boundaries Collaborative District, an AANAPISI Grant supported by the U.S. Department of Education, and co-sponsored with the APIDA + Center and the Ati: Wa:oki Indigenous Community Center. Their visit is part of programming for APIDA Heritage Month Commemorating the 30th anniversary of diplomatic relations between Viet Nam and the United States, and the 50th anniversary of engagements in Southeast Asia. Special thanks to Co-Organizer Scott Fralin. The exhibition reception is co- sponsored by the Residential College at West Ambler Johnston.
Statistics and Stories: American Soldiers and the 1918 Flu
Fralin, Scott; Ewing, E. Thomas (Virginia Tech, 2024-11-08)
This student-created exhibit in Newman Library (floors 1-4) featured posters researching Virginia soldiers who died from the 1918 flu epidemic during World War I. The project, developed by students in the HIST 2624 class, examines quantitative military medical records and individual soldier stories. This "Statistics and Stories: American Soldiers and the 1918 Flu" exhibit is on display through the semester.
