Water is the most precious resource for civilization and every person should expect access to a clean, safe water supply. Delivering this basic right, however, is not trivial where many of the poor live in water-stressed or polluted environments. Understanding the hydrogeological mechanisms of water flow through watersheds and groundwater systems is, therefore, essential in trying to secure the access to water that populations, agriculture, wildlife, and industry need in order to prosper.
Stable oxygen and hydrogen analysis of environmental waters can provide a unique understanding and characterization of many hydrogeological systems. Determination of these isotopes gain an understanding of reservoir residence times, groundwater recharge rates, and mixing models. Stable isotopes analysis also helps constrain river basin dynamics in catchment hydrology to aid water management and develop strategies for extreme weather events and reducing the impact of droughts.
