One of very efficient ways of removal of oil contamination is microbiological degradation. The influence of the concentration of contaminants on bacteria count is of a two-fold character: if the concentration is extremely low, the microorganisms cannot taste contamination, and when it is extremely high then oil is toxic to them. In order to investigate bioremediation of soil and groundwater polluted with oil and oil derivatives, the contaminated soil was placed in a laboratory bioreactor, water poured in, and then its recirculation was carried out. The remediation process was followed by measuring the changes in concentration of hydrocarbons and counts of particular bacteria groups in water with the change of water flow rate in the course of the experiment.
