This program provides a clickable periodic table that links elements to additional information about their isotopic systems. Information is provided about the isotopes important to hydrology, their applications, how they are measured, and how much it costs for an analysis.

Material for this web site was developed by SAHRA with the assistance of students in Brenda Ekwurzel's Environmental Isotope Hydrology class in the Department of Hydrology and Water Resources at the University of Arizona. The site is still in progress; information will be added as it becomes available.
