I use environmental tracers (properties of the water molecule or compounds dissolved in water) to understand the origin of water (rainfall, river infiltration, etc.) and the time since a given water source has entered the water cycle. The latter is especially important to evaluate the sustainability of groundwater resources. Current applications include the evaluation of connectivity between geological formations in unconventional gas settings, aquifer recharge rates, groundwater - surface water interactions, and submarine groundwater discharge.
