• Abstract:

  The contamination of groundwater by petroleum-derived fuel has been the subject of increasing research in Brazil. The compounds, benzene, toluene, ethylbenzene and xylenes (BTEX), present in these fuels, are extremely toxic to human health and the environment. The remediation of contaminated aquifers and soils depends on knowledge of the physical and chemical parameters of each site to quantify the flows and transport of contaminants in groundwater. This quantification has been done through mathematical modeling used in computational models, one of these most used models is BIOSCREEN. The objective of this work is to evaluate the use of the BIOSCREEN model to monitor the evolution of the contaminant plume, the extent of the affected area and the prediction of the time for restoration of water quality in the studied region. The case study discussed in this article refers to an accidental leak that occurred at a service station located in the neighborhood of Brisamar, municipality of Itaguaí/RJ. The aforementioned station has one alcohol tank, two gasoline tanks and two diesel tanks, each of these tanks with a capacity of 15,000 L. It was concluded that: after carrying out the study, it was not possible to evaluate the evolution of the contaminant plume for this site through the BIOSCREEN computational model due to the limited number of experimental parameters.
