ECOANALYTICAL CONTROL OF SURFACE WATERS IN THE ZONE OF INFLUENCE OF THE YAMBURG OIL AND GAS CONDENSATE FIELD

Abstract

The article is devoted to the actual problem of surface water monitoring in the zone of influence of oil and gas producing enterprises. Aims and Objectives – comprehensive pollution assessment of natural water bodies located in the zone of influence of wastewater injection landfills of the integrated gas treatment plants IGTP-1 and IGTP-2 of the Yamburg Oil and Gas Condensate Field using the water pollution index. The pollution assessment of natural waters was carried out in accordance with State Standard 17.1.3.07-82 «Nature protection. Hydrosphere. Procedures for quality control of water in reservoirs and stream flows». The average regional values of the controlled components correspond to the «Handbook on the use of average regional values of controlled Component content at monitoring Sites when assessing the state and level of environmental pollution in the Yamalo-Nenets Autonomous Okrug». It has been concluded that, on average, the water pollution index of the studied territory for the period since 2019 up to 2021 corresponds to the 2nd quality class («clean»), excluding from the calculation the concentration of iron – a typomorphic element of the natural waters of the North taiga zone.
