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." professional_experience: [] title: Hydrologist
