A tracing technique for determining the average porosity and the permeability of the various layers of a stratified aquifer is presented. The average porosity and the different permeabilities of the four layers of a shallow sandstone aquifer were determined by tracing a pulse of K 3 Co 60 (CN) 6 between two wells located 15 meters apart, as well as by using standard pumping‐test techniques. The results were confirmed by the salinity balance of the aquifer. The experiment has indicated the usefulness of radiotracer techniques combined with standard pumping techniques and chemical analyses for the study of microstructural properties of sandstone aquifers.
