Understanding and preserving the genesis of natural mineral and spa waters is a matter of keen interest. Under a complex analysis programme, Sr-87/Sr-86 ratios (as well as other isotopes) were measured in such waters at various sites in Saxony, producing values ranging between 0.708 and 0.731. The strontium isotope ratio was found to be closely linked to the flow patterns and variations in the chemical composition of water. The Sr-87/Sr-86 ratio can thus be used as an indicator to characterize groundwater-rock interaction and hence the variation of flow paths. It is especially useful for differentiating waters in a lithologically heterogeneous aquifer system. However, it haste be applied together with other methods and different samples from the same area should be compared.
