Oil industry is one of the sectors that influence on all components of nature. In case of Middle Ob where a lot of lakes and swampy territories are located, surface waters are influenced by the industry. The longer the terms of oil extraction and the construction time of anthropogenic objects, the higher the chance of the change of hydro chemical and hydrogeological structure of water objects. But during the status assessment of surface waters, it’s important to take into consideration that a lot of water objects are located beyond the licensed sites. It’s important to take the trans-frontier characterization of the waterfowls. To such oilfields the Vostochno-Elovoye oilfield, through territory of that flow a lot of rivers and the territory of which is developed by a lot of resource users, is considered. But the greatest influence provides the Ob River that flows from the south-east. In its’ waters there are the greater amounts of polluting substances, exceed the allowable threshold concentration. To estimate the condition of external pollution on the territory of oilfield, the hydrological researches are made.
