Previous issue date: 2009-06-30 / This work is the application of geophysical methods, using the Ground Penetrating Radar (GPR), with the objective of survey in a subsurface plume of contamination caused by a disabled gas station. The gas station is located on the B?zios beach in southern coast of the state to Rio Grande do Norte in an Area of
Environmental Protection called Bonfim-Guara?ra. The interest to develop this work was the presence of contaminants (hydrocarbons) in a well located on the desktop, previously used for the abstraction of groundwater for residents living near the site. Were raised 15 geophysical survey lines totaling 775,48 lifting and installed 4 piezometer, to confirm the contamination and prepare a pluviometric map that helped in indicating the direction of local groundwater flow, thus showing the direction of movement of the probably plume of contamination. From the processing of the GPR lines was possible to identify two likely phases of contamination according to the classification proposed by Azambuja et al 2000, which are called phase absorbed and dissolved phase / A presente disserta??o corresponde a aplica??o da metodologia geof?sica, utilizando para isto o Ground Penetrating Radar (GPR), com o objetivo de obter um imageamento em subsuperficie de uma pluma de contamina??o ocasionada por um posto de revenda de combust?vel que se encontra desativado. Este posto
esta localizado na praia de B?zios litoral sul do estado do Rio Grande do Norte dentro de uma ?rea de Prote??o Ambiental denominada de Bonfim-Guara?ra. Esse estudo foi realizado a partir da descoberta da contamina??o por hidrocarboneto obtido atrav?s de sondagem realizada para capta??o de ?gua
subterr?nea por moradores que residem pr?ximo ao local. Foram levantadas 15 linhas de sondagem geof?sica totalizando 775,48 metros de levantamento e instalados 4 piez?metros, para confirma??o da contamina??o e elabora??o de um mapa potencim?trico que auxiliou na indica??o do sentido do fluxo
subterr?neo local, mostrando assim o sentido de movimenta??o da pluma de contamina??o. A partir do processamento das linhas de GPR foi poss?vel identificar duas prov?veis fases de contamina??o de acordo com a classifica??o proposta por Azambuja et al 2000, as quais s?o denominadas de fase absorvida e fase dissolvida
