Abstract: Sangemil spa area is located 16 km south of Viseu, Central Portugal, near the Dão river. The productive wells, F1 and F2 are located in the alluvial plain of the river and have been threatened by the river floods (Fig. 1). In order to locate new production wells, out of the alluvial plain and close to the spa unit the surrounding geological structure was surveyed. The proposed structural model claimed for a geophysical survey with two profiles P1 and P2 (Fig. 1) using dipole-dipole array. Taking into account the results obtained, three new wells, HDN1, HDN2 and HDN3 (Fig. 1) have been drilled (85 to 112m deep). The field measurements of conductivity, temperature, pH and yield are discussed in conjunction with the geophysical results.
