Utilização Integrada De Métodos Elétricos E Do Gpr Na Análise Ambiental Do Aterro Sanitário De Jundiaí – Sp

This paper reports the results of a geophysical<br>research in the waste disposal located at Jundiaí-SP.<br>This site is typified by waste cells, which have<br>significant quantities of material above the water<br>table. The main objectives were: to characterize the<br>structure of the waste disposal in subsurface, to<br>determine the depth of the water table, the direction<br>of the groundwater flow and to map the<br>contamination plume. Vertical electrical sounding<br>(VES), electrical profiling and ground penetrating<br>radar (GPR) were used in an integrated way. Based<br>on the VES resistivity values, it was possible to<br>identify the contaminants in the sediments and the<br>depth to the water table. The results of the electrical<br>profiling integrated to the GPR allowed for the<br>mapping of conductivity lateral variation, with higher<br>condutivity zones interpreted as more contaminated<br>sites or fractured zones in the bedrock. As a final<br>product, a potentiometric map indicates the<br>preferential groundwater flow.
