The site is located close to Paranaguá harbor, in the Paraná State, Brasil. At this site, high chloride concentration contaminated shallow water wells used to supply water for local industries. The site investigation program included a fieldwork, dipole-dipole electrical profiling, resistivity piezocone tests, physical-chemical analysis of sampled water and interpretation of borehole logs. The resistivity piezocone tests provided two simultaneous information; the soil stratigraphy at a very detailed level and a quasi-continuous resistivity profile. Both information adequately complemented dipole-dipole electrical profiling test data. The integration of all test data allowed identifying the contaminated areas as well as guided the location of new water wells to be installed in this area.249-260porChlorideContaminationDipole-dipole electrical profilingPiezoconeResistivitySite investigationAquifersConcentration (process)Electric conductivity measurementSalt water intrusionSedimentsShallow aquiferOceanographyArtigoAcesso restrito2-s2.0-319444489360781618586438933
