| Sumario: | Measurements of natural tritium in surface and groundwater and of carbon-14 in wells are used in order to study the functioning of the aquifers in the Cariri area in the south of Ceará State at the border with Pernambuco State. A laboratory for eletrolytic enrichment of natural tritium has been installed. Measurements were in agreement witch those obtained by Gessellschaft für Strahlen-und Umweltforschung mbH München - GSF / Germany and International Atomic Energy Agency - IAEA / Vienna. Interpretation of the data was made using mathematical models which permit the determination of parameters that describe the dynamics of the aquifers Missão Velha and Feira Nova. For the latter the transit time was determined, the thickness of the satured layer at the Feira Nova/Santana contact and rate of infiltration were estimated. In addition to these data natural carbon-14 measurements were made in the lower Missão Velha and upper Missão Velha which are separated by a leaky clayey layer. |
