Brief content	The amount of potentially hazardous substances entering the ecosystem is increasing every day. With the increase in usage of groundwater for drinking purposes, it is crucial to monitor groundwater quality. Pollutants have emerged as a global concern due to their ubiquitous presence in the hydrological systems. A separate process of biological degradation is not sufficiently effective, and the accumulation of these substances occurs. This paper is focused on expanding existing knowledge of degrading BTEX (benzene, toluene, ethylbenzene, p-xylene) substances by ozonation process in groundwater before biological degradation. The results show that the degradation efficiency of these compounds with previous ozonation was much higher in comparison with non-ozonated samples. Also, total number of attached cells was during the whole experiment in the case of the ozonated samples higher, which indicates that suitable conditions for biomass formation have been created.
