Previous issue date: 2011-01-31 / Among the potentially polluting economic activities that compromise the quality of
groundwater are the gas stations. The city of Natal has about 120 gas stations, of which
only has an environmental license for operation. Discontinuities in the offices were
notified by the Public Ministry of Rio Grande do Norte to carry out the environmental
adaptations, among which is the investigation of environmental liabilities. The
preliminary and confirmatory stages of this investigation consisted in the evaluation of
soil gas surveys with two confirmatory chemical analysis of BTEX, PAH and TPH. To
get a good evaluation and interpretation of results obtained in the field, it became
necessary three-dimensional representation of them. We used a CAD software to graph
the equipment installed in a retail service station fuel in Natal, as well as the plumes of
contamination by volatile organic compounds. The tool was concluded that
contamination is not located in the current system of underground storage of fuel
development, but reflects the historical past in which tanks were removed not tight
gasoline and diesel / Dentre as atividades econ?micas potencialmente poluidoras que comprometem a
qualidade das ?guas subterr?neas est?o os Postos Revendedores de Combust?veis. A
cidade do Natal possui cerca de 120 postos de combust?veis, dos quais, apenas um
possui licen?a ambiental de opera??o. Os postos em desconformidade foram notificados
pelo Minist?rio P?blico do Rio Grande do Norte para realizarem as adequa??es
ambientais, dentre as quais est? a investiga??o de passivo ambiental. As fases
preliminar e confirmat?ria desta investiga??o consistiram na avalia??o de gases do solo
com duas sondagens confirmat?rias para an?lises qu?micas de BTEX, HPA e TPH.
Para obter-se uma boa avalia??o e interpreta??o dos resultados obtidos no campo, se fez
necess?rio a representa??o tridimensional dos mesmos. Utilizou-se um software CAD
para representar graficamente os equipamentos instalados em um posto revendedor de
combust?vel em Natal/RN, assim como as plumas de contamina??o por compostos
org?nicos vol?teis. A partir desta ferramenta foi poss?vel concluir que a contamina??o
n?o est? localizada no atual Sistema de Armazenamento Subterr?neo de Combust?vel
do empreendimento, mas reflete o hist?rico passado em que foram removidos tanques
n?o estanques de gasolina e diesel
