A study covering the shallow subsurface was developed in order to investigate the possibility of underground contamination by liquids used in the treatment of animal skin. The study was carried out inside the area of the Couro do Norte industry, located in the Icoaraci Industrial District (Belém – Pará). During the study they were made measures for the determination of the flow of water of the first aquifer and applied geophysical methodology with the purpose of detecting the possible contamination of the underground for pollutant liberated by the tanning. The geophysical methodology applied was: resistivity (imaging and vertical electric soundings), spontaneous potential, electromagnetic (Slingram) and ground penetrating radar (GPR). Analyses of electromagnetic data lead to the identification of conductive zones (Contamination) and resistive zones (sandy material). Spontaneous potential gave information on the direction of local underground flow of water. Vertical electric soundings allowed to know the resistivity distribution in subsurface. The resistivity sounding models could be correlated to the electrical images obtained in electrical profiling. Through the GPR data was possible to identify the presence of lateritic blocks, metal piping and zones with high attenuation (shadow zones) that indicate the presence of contamination.

A study covering the shallow subsurface was performed in order to investigate the possibility of underground contamination by liquids used in the industrial processing of dead animal skin to produce tanned hide. The study was carried out inside the area of the Couro do Norte industry, located in the Icoaraci Industrial District (Belém-PA). The used geophysical methodology was: resistivity (imaging and vertical electric soundings), spontaneous potential, electromagnetic (slingram) and ground penetrating radar (GPR). The integrated geophysical interpretation of data indicated the underground flow direction and a shallow plume of contamination, caused probably by the disposal of effluents by the Couro do Norte industry.
