Environmental Isotopes in Groundwater Studies: Groundwater, Environmental Isotopes, and Salinity

Learn how environmental isotopes — important in tracing groundwater flowpaths and recharge origin — can be used with geochemistry to trace the source of salinity in this webinar, a part of the Environmental Isotopes in Groundwater Studies webinar series.

In addition to oxygen-18 and deuterium, isotopes of chlorine and sulfate are increasingly used routinely to trace rock/water interaction and mixing with saline sources in the subsurface. This webinar will look in some detail at a few of these important isotope systematics :

• Sources of salinity in groundwater
• Strontium and sulfur isotopes
• Isotope partitioning in advanced rock/water/gas reactions
• Sampling and analysis
• Case studies for groundwater contamination from saline sources.
