The applications of environmental isotopes as hydrologic tracers in low-temperature, freshwater systems fall into two main categories (i) tracers of the water itself (water isotope hydrology) and (ii) tracers of the solutes in the water (solute isotope biogeochemistry). These classifications are by no means universal but they are useful conceptually and often eliminate confusion when comparing results using different tracers. 

Krouse and Mayer (2000) present an in-depth review and several case smdies of the use of stable sulfur and oxygen isotopes of sulfate as hydrologic tracers in groundwater. In addition, the use of sulfur isotopes for investigations of hydrological processes in catchments has been reviewed by Mitchell et al. (1998). Thus, what is presented here is just a brief overview of the application of sulfur isotopes in hydrologic studies.

However, this simple picture is complicated by a large number of factors other than site temperature that can affect or 5D of fossil waters. In aggregate, the effect of these additional factors may be small, or may exceed the effect of temperature. For this reason, much recent work has moved away from paleothermometry based on or 5D. Instead, or 5D are increasingly being used as hydrologic tracers. Much of the power of these analyses results from coupling of interpretations of or 5D of water with temperature reconstructions based on other techniques, which often use multiple parameters and which often exploit simpler systems.

It has been common belief for many years that the abundance in meteoric waters carries no additional information to that of Although mass-independent fractionations are not known to occur in water, H2 0 is a useful tracer within the hydrologic cycle (Angert et al. 2004 Luz and Barkan 2007). Improvements in analytical techniques allow to measure and 5 0 with a precision of a few 0.0 l%c which permits calculation of with similar precision and the tracing of very small variations.
