Some physiological groups of bacteria can be good indicators of the oil pollution of the environment. Oil contamination represents a special problem because of their persistence and possibility of reaching drinking water supply sources. The destruction of the Novi Sad Oil Refinery in the hinterland of water supply source Ratno Ostrvo has endangered drinking water supply of the city of Novi Sad. As an acceptable protection measure appeared the solution with the hydraulic barrier located along the east side of the Refinery, bordering with the water supply source. Physiological groups of bacteria relevant to oil contamination (hydrocarbon-oxidizing and lipolytic bacteria) were detected in the waters of the barrier wells. The appearance and population of this microflora in the water of these wells were more pronounced compared with the waters of a control piezometer in the hinterland of the water supply source.

Wastewater from the Novi Sad Oil Refinery, Serbia (Serbia and Montenegro) had been previously discharged to the Danube river between the raw water wells. In order to protect water supply source, the collector discharge was displaced downstream, outside the raw water wells area. In 2004, the quality of Danube river water and sediment was monitored at the sites of the old and new collector discharge of the Oil Refinery wastewaters, as well as at two control (reference) sites. The paper presents chemical quality parameters of water and sediment, characterizing oil contamination. Significantly increased contents of oil contaminant were measured in the Danube river sediment at the old discharge site compared to other sampling points, which is a consequence of many-year accumulation, as well as in the Danube river water at the new discharge site, as a consequence of the present wastewater discharge.
