USGS intern Kira Waldman collecting water-quality samples

Each summer, interns join USGS offices around the Nation in support of our water studies. In this photo, USGS intern Kira Waldman conducts field work in June 2019 as part of a long-term study near Bemidji, Minnesota, to understand mobilization, transport, and fate of crude oil in the shallow subsurface. Kira is pushing a sample screen into lake bottom sediments to collect a sample of pore water from below the lake bed to help us understand how contaminants may be migrating from the historical oil release into the lake. Kira's internship at USGS was supported by the Middlebury College Center for Careers and Internships.
