Topical Session 33
Innovative uses of environmental isotopes in hydrology

Description:
Environmental isotopes have been used extensively for identifying sources and processes controlling the movement of water and contaminants in the hydrologic cycle.  Though widely used, isotopic measurements and applications still are changing rapidly.  New analytical procedures provide access to more compounds and to more subtle isotope variations.  New datasets provide evidence for previously unrecognized isotopic effects.  New experiments involving both “natural isotope abundance” measurements and “deliberate isotope tracer” injections reveal increasingly complex transport and reaction scenarios in the environment.  This session provides a forum for research aimed at expanding the scope of isotopic applications in hydrologeology and biogeochemistry, through development of techniques and creative applications.
