Environmental Tracers in Subsurface Hydrology

This text synthesizes the research of specialists into a comprehensive review of the application of environmental tracers to the study of soil water and groundwater flow. It includes chapters which cover ionic tracers, noble gases, chlorofluorocarbons, tritium, chlorine-36, oxygen-18, deuterium, and isotopes of carbon, strontium, sulphur and nitrogen. Applications of the tracers include the estimation of vertical and horizontal groundwater velocities, groundwater recharge rates, inter-aquifer leakage and mixing processes, chemical processes and palaeohydrology.
