Resumo

One of the many applications of stable isotope analyses is in hydrological studies.
As the isotope concentration of elements in water vary as a result of fractionation due to
physico-chemical processes, each water has its own “fingerprints”, so that identification of its
origin is made possible. This technique has been used in the investigation of the possible
leaks through the geologic formation underneath the Tapacurá Dam, near Recife, Brazil.
Samples were collected from the reservoir and from several collection points downstream.
These samples have been analysed for their deuterium, 18O and 13C concentrations. The
comparison between results from these analyses indicated that water from the reservoir and
from the other collection points had distinct origins. These findings were corroborated from
standard chemical analyses and tracer studies, thus pointing to the absence of any significant
underflow at the Tapacurá Dam
