The article considers the results of the studies of small rivers in the area of operation of the Oil Pump Station 29 in the Amur Region. The high content of organic substances and the saturation of water with oxygen in the Arkhara River indicates eutrophication, which is restrained by a short period of hydrological summer. The content above MPC of total iron and silicon is due to regional peculiarities. The orthophosphates found in the rivers of Uril and Suhusha are of pyrogenic origin. In the rivers of Arkhara, Uril, Suhusha the high content of polyphosphatesis identified. The total content of volatile phenols and petroleum products in the rivers did not exceed the MPC. The results of hydrochemical parameters of small rivers are the basis for the further study of anthropogenic load on the watercourses of the territory of operation of the Oil Pumping Station.

a small river, eutrophication, organic substances, the Amur Region.
