Complex chemical-analytical and microbiological studies of the state of water, soil grounds and bottom sediment of the industrial zone of city of Khabarovsk were carried out. It was found that petroleum prodacts are the main environmental pollutant of the study area. The impact of runoff from the industrial zone on the quality of water and bottom sediments of the Amur river is manifested in an increase in their content and number of indicator groups of bacteria in the zone of impact of the small river Kurcha-Murcha draining the territory of the industrial zone. The oil content in the Kurcha-Murcha river at the exit from conduit is 20 MPC. The degree of soil contamination varies from “increased-background” to “strong”. The amount of oil products in the bottom sediments of the Kurcha-Murcha and the Amur river (below the mouth of the Kurcha-Murcha river) is defined as "dangerous" and "strong", respectively.
