Résumé:
The groundwater supplies much of the population and its contamination is a matter of public interest. Fuel stations are potential sources of contamination, due to their extensive distribution network and also the storage of product being predominantly undergrounded. Within the methods for detecting hydrocarbons, geophysicists provide research in larger extents, with more quickly and at a lower cost. The research intends to show the method of remediation in subsurface environments that present these contaminations by petroleum derivatives, lower cost and more efficiency. The theoretical assumptions underlying this study were the consultation in specific literature on the subject: hydrogeology of petroleum hydrocarbon contamination. The research is predominantly theoretical and does not aim at the exhaustion of the theme, but rather serves as a source of consultation for analysis and reflection on the harm of contamination in subsurface environments, as well as the importance of remediation techniques to prevent the pen from spreading, causing major damage. In the literature review, several topics were discussed, for example: Analyze the behavior of petroleum
hydrocarbons in subsurface environments; The phases of contamination in subsurface environments; The structural geology to better understand the geometry of fractures and estimate the preferred paths of DNAPL and in free and dissolved phases; The most effective methods for remediation of contaminated areas; Diagnostics and
monitoring of contaminant feathers in subsurface environments.
