| Resumo: | The fuel retailers carry out activities with high polluting potential due to the storage of large quantities of liquid fuels. One of the main impacts caused by leakage of petroleum derived fuels is the contamination of soil and groundwater by toxic compounds, especially monoaromatic hydrocarbons such as benzene, toluene, ethylbenzene, o-xylene, p-xylene and m-xylene (BTEX). In the municipality of Natal, groundwater has a determining role in public supply and increasingly has been used for commercial use and in services. In this perspective, the main objective of this research was to carry out an environmental diagnosis of fifteen (15) liquid fuel retailers in the city of Natal/RN and, thus, propose points that will form part of a network of qualitative monitoring of groundwater in the city to monitor the presence of BTEX compounds in the aquifer. The data were collected through the application of a questionnaire in the format checklist with questions regarding the current environmental legislation related to the sector, equipment and environmental controls required. A form was also used to guide the georeferenced cadastre of the tubular water wells in the reseller stations. The results allowed to conclude that only one (1) station was in disagreement with the environmental license and two (2) stations did not respect the minimum distance required in the fuel tank vent. In relation to environmental monitoring, it was possible to note the deficiency of the monitoring network. Only one (1) station had a tubular well in the project area and the existing monitoring network developed by Água Azul Program was inconsistent. In this way, it is necessary to select and propose sampling points to compose a network of qualitative monitoring of Natal’s groundwater, based on data from pre-existing tubular water wells. |
