Irvine, Calif., Aug. 4, 2022 — A cross-disciplinary team of engineering, biological sciences, public health and anthropology graduate students from the University of California, Irvine took first place in Phase 1 of the Environmental Protection Agency’s Environmental Justice Video Challenge for Students for their “Unearthing Lead: The Power of Historical Maps” entry, which reveals the dangerous levels of lead in soils in Santa Ana.

The EPA asked college students across the country to create a video “demonstrating innovative approaches to identify and characterize an environmental justice issue in a select community using data and publicly available tools” and were encouraged to collaborate with neighborhood groups to bring a local perspective of challenge they are facing. The UCI student team collaborated with faculty from the Program in Public Health and members of the Orange County Environmental Justice organization to create the video.

Unsafe lead concentrations in the soil is a primary concern of Santa Ana residents in urban, disadvantaged neighborhoods. The video shows how a mixed-model approach combining historical and statistical methods was used to determine that lead-based paint and leaded gasoline were the two main sources of lead contamination which disproportionately affected the city’s communities with lower socioeconomic status.

“This award is a recognition of the collaborative relationships our team built between OCEJ and UCI researchers. Moving forward, the video will help launch the next phase of communicating the research findings on the national level, with the possibility to inspire action in similarly impacted communities,” said Tim Schütz, anthropology Ph.D. candidate and videographer. “It also supports my dissertation research about the role of data and digital technology in environmental activism. As part of the award nomination, our team is planning to submit a peer-reviewed journal article that discusses the use of videos, podcasts and other creative media that help make lead soil contamination a matter of public concern.”

The team also included graduate students Annika Hjelmstad, Ariane Jong, Ashley Green and Irene Martinez, all in civil & environmental engineering; Javier Garibay, civil engineering; David Bañuelas, ecology & evolutionary biology; and Alexis Guerra, environmental health sciences. Schütz and Bañuelas were fellows in the UCI Newkirk Research Justice Shop. The video was produced as part of the year-long training program and practicum in community-based research.

“The video highlights how community-based organizations in the places most impacted by environmental injustices, such as OCEJ and GREEN-MPNA, who are featured in the video, are collaborating with UCI researchers to produce findings that will advance the understanding and mitigation of EJ problems by integrating community knowledge and techno-scientific knowledge in research practice,” said Connie McGuire, RJS director of community relationships and faculty advisor on the students’ EPA Video Challenge submission.

“It’s been such a privilege to work with such a dedicated and talented group of UCI students, faculty and community members on this important work relating to lead contamination in Santa Ana,” said faculty collaborator Shahir Masri, associate specialist of environmental and occupational health with the UCI Program in Public Health. “The team’s video will play a critical role in shedding a light on the environmental injustices facing Santa Ana residents, as well as those in other parts of the country and world to whom environmental inequities play a role in their everyday lives. The end goal, we hope, will be government-assisted remediation of the soil and access to resources to help prevent lead exposure in the community, particularly among the most vulnerable and socioeconomically disadvantaged neighborhoods.”

Jun Wu, professor of environmental and occupational health, and Alana LeBrón, assistant professor of public health and Chicano/Latino studies, both with the UCI Program in Public Health, also served as faculty collaborators.

“Addressing environmental justice concerns is a core part of our work at EPA,” said Chris Frey, assistant administrator for EPA’s Office of Research and Development. “This challenge empowered young people to bring attention to important environmental and public health issues. I look forward to seeing how students collaborate with communities to advance environmental justice in the second phase of this challenge.”

Awards of $20,000, $12,000 and $6,000 were awarded to the Phase 1 first, second and third place recipients, and the seven honorable mentions each received $1,000. A September launch is planned for Phase 2 of the competition, which will be open to all eligible Phase 1 applicants. Students will collaborate with their community partners to develop a strategy or proposal that demonstrates effective engagement and advocacy to address the environmental issues identified in Phase1.
