You will gain insight on the use of radioisotopes to constrain estimates of groundwater age and rates of flow in this webinar, a part of the Environmental Isotopes in Groundwater Studies webinar series*.
Environmental isotopes in hydrogeology focus on the stable isotopes as tracers of groundwater recharge, mixing, and interaction with surface waters. This webinar looks at constraining the rate of circulation, or determining the age of groundwater, and looks at the use of radioisotopes to constrain estimates of groundwater age and rates of flow. For applications that involve relatively modern groundwaters, tritium and its daughter helium-3 are routinely used. Older waters can be dated with radiocarbon, and much older systems with iodine-129 and chlorine-36. The theory and application of these radioisotopes will be presented. Topics to be covered include:

*About the series
The Environmental Isotopes in Groundwater Studies webinar series is designed to acquaint you with new inexpensive technologies for rapid analysis of isotopes in waters and solutes, and the integration of environmental isotopes with geochemical techniques, which have never been more accessible to practitioners, regulators, and students. Geared toward the professional or student with some background in hydrogeology and basic aqueous chemistry, presentations during the series include some theoretical background, but also rely on selected case studies to demonstrate the applications in real situations. Each hour-long webinar is structured as a standalone offering, so you may attend one or all of them. The other webinars in the series include:
