Kaela Gollob is a senior at Iowa State University with a double major in Geology and Environmental Science. She plans to focus on hydrogeology in graduate school after her graduation in the spring of 2020. When she is not in class, she works as a lab technician intern for the USDA National Lab for Agriculture and the Environment on campus and as a manager for the ISU Outdoor Recreation Program, where she has led backcountry trips to Utah, Georgia, and Arkansas. In her free time, she loves to enjoy the outdoors, especially by backpacking, kayaking, and traveling.
Project:Kaela’s project tested the hypothesis that nitrate-N is transported from a losing reach of the South Skunk River, where denitrification removes nitrate-N in the adjacent alluvial aquifer. The objectives were to investigate the seasonal variability of nitrate-N in the South Skunk River and its variability with depth in the alluvial aquifer; and to document the process of denitrification in the aquifer and identify the source(s) of nitrate-N. The results of this investigation improve our understanding of nitrate-N occurrence in alluvial aquifers used for municipal drinking water.
