This work helps to identify areas where poor water quality may limit the use of fresh water for agricultural, industrial, and drinking water uses.Courtney also applies machine-learning techniques to predict groundwater levels through time at ungaged locations across an aquifer. Courtney's research has included groundwater and surface-water interaction studies, low-flow groundwater quality sampling for age tracers, isokinetic depth-integrated surface-water sampling, and nuclear magnetic resonance borehole and surface imaging. She enjoys using R and Python programming in conjunction with GIS to help answer regional water availability questions."
