Tracking Groundwater with Isotopes

Volume 2 Number 1 January/February 2003

Isotopes can be powerful tools in the field of hydrology, able to provide definitive answers to questions of recharge and flowpaths that many thousands of dollars’ worth of aquifer tests, new boreholes, and models may not. But what are isotopes, really, and how does one begin to figure out which ones could be applied in a particular setting? Several experts in the field discuss interpretation, analyses, and costs, and present case studies to illustrate how they have been applied successfully in Southwest basins. And, if you want to learn more, we provide the references to take you further.
