In the beginning of the 1980’s, the process of adding methyltertiary-butylether (MTBE) instead of tetraethylplubane to gasoline began. Using MTBE as a fuel oxygenate has became very popular due to its low price and excellent solubility in gasoline. Con-centrations of MTBE in unleaded gasoline range between 10–15% of the volume. However, there are significant negatives related to its release into the environment. This contribution describes the behavior of MTBE, BTEX and TPH after the large accidental release of gasoline from product pipeline into the rock environment. Geological composition of the affected site shows the difference of behavior of the pollutants in fractured rock environment and the intrinsic permeability rock environment in time. Remediation process took more than five years and monitoring data were available for the study. By comparing the length of migration of MTBE components with BTEX and TPH components in the rock environment of the locality, the theory that MTBE component migrates faster in geological environment than BTEX components and TPH, has been confirmed. Movement of pollutants in fractured rock environment is several times faster than the intrinsic permeability rock environment on site.
