| Summary: | In the scope of the Metropolitan Region of Fortaleza (RMF) the problems with salt contamination of coastal aquifers are still effective in local level. They take place associated to extractions for batteries of tubular flat wells operating in dunas/paleodunas system or, through tubular deep wells arranged along the coast, chaotically operated, in the general one, and, nearly always deprived of any system of qualitative or quantitative control. This work summarizes the theoretical and methodological bases of use of the inductive electromagnetic method in the domain of the frequencies (FDEM), mapping, to different depths, the saline flow in Pacheco beach. This paper emphasizes the use of the method like a versatile tool in the study of the contamination by salts, with the possibility of temporal and spatial control of its evolution, giving subsidizes, by its good definition, to the establishment of a net of wells and piezometers of control. |
