| English abstract | The actual sanitary landfill deposit of Alagoinhas county was constructed at the neighborhood of an old city dump and of a large tannery industry. Such dangerous pollution sources are located above the recharge area of the S˜ao Sebasti˜ao aquifer, one the most important water reservoirs of Bahia state, being exploited to supply human and animals populations in the county, irrigated agricultures and industries. To characterize the hydrological and environmental changes generated both by landfill leachates and tannery byproducts we applied electrical geophysical surface measurements combined with water samples physical chemistry analysis. The results of 49 vertical electrical soundings were used to delineate a three-dimensional conductive anomaly, which extends from the water table (about 10 m depth), to more than 40 m in depth. Such anomaly is interpreted as a result from the invasion of aqueous fluids derived from the garbage deposits and from the tannery decantation lagoon into the upper phreatic, regional aquifer of the area |

Tais fontes perigosas de poluicao estao situadas sobre uma area de recarga do aquıfero Sao Sebastiao, um dos mais importantes reservatorios de agua doce do estado da Bahia, que e intensivamente explorado para suprimento das populacoes humanas e animais, irrigacao e industrias. Uma caracterizacao das alteracoes hidrologicas e ambientais geradas pela presenca dos depositos de lixo e da industria de couros foi realizada por meio da aplicacao de metodos geofısicos eletricos combinados com an´alises fısicoquımicas de amostras de aguas |
