Gas stations and services, based on hydrocarbon compounds, can contribute to the contamination of soil and groundwater, giving environmental liabilities and risk to human health, due to their toxic, mutagenic and carcinogenic nature. In 2015, an environmental assessment was carried out, with the merit of measuring the risks of contamination at two gas stations located in the Metropolitan Region of Salvador-RMS, State of Bahia. In this research, the results showed that although the two areas (Gas Station 01 and Gas Station 02) showed signs of contamination by Polycyclic Aromatic Hydrocarbons (PAHs) and Mono-aromatic Hydrocarbons (BTEX), although only Gas Station 01 confirmed the contamination by Ethylbenzene (2.58µg/L) and Naphthalene (17.632 µg/L) due to the analytical results above the maximum allowable values (VMPs) of the U.S. Environmental Protection Agency - EPA), but did not reach those levels in Resolution nº 420 CONAMA – National Environment Council. Conservative measure was applied to protect the health of restaurant users by recommendation to interrupt the use of underground water from the pumping well (PB) for dermal contact and human supply at Station 01, to mitigate the source of contamination and risks to human health. The restaurant was decommissioned in 2023.
