Isotopes

This book provides an overview of common tracer methods that can be used for age dating young groundwater that recharged less than about 60 years ago.

The stable isotopes of hydrogen and oxygen in the water molecule can provide insights into the movement of water that chemistry and physical methods (water levels, etcetera) sometimes cannot. Whether in the atmosphere, biosphere, hydrosphere or geosphere, stable isotope compositions can be used to trace flows of water, sometimes quantitatively. These flows include the key

This book addresses the use of environmental tracers and environmental isotopes for identifying groundwater sources and quantifying rates of groundwater recharge, discharge, flow, and mixing. Its goal is to present the application of the techniques in a form that can be readily understood and appreciated by groundwater professionals who do not have a background in
