Streambank sediments can be an important source of phosphorus to Wisconsin waterways, driving eutrophication and negatively impacting aquatic health, human health, and local economies. There is limited understanding of how groundwater–surface water exchange in the hyporheic zone impacts streambank sediment phosphorus storage, and this study aims to quantify these processes. Students will characterize sediments, phosphorus associations, and subsurface hydrology at two sites in central Wisconsin. Project duties include (1) leading field campaigns to seasonally sample sediments and streambank porewater, (2) running analytical equipment to collect water quality data, and (3) conducting batch experiments on sediment samples to evaluate the biogeochemical conditions that promote storage and release of phosphorus. Project findings are anticipated to inform land, nutrient, and water management decisions.
