Abstract

AbstractThe problem of ensuring environmental safety in the processing and disposal of oil-containing and drilling waste is relevant in almost every oil-producing region of Russia. The impact of technological complexes (TCs) for the treatment and disposal of oil waste on the environment has not been actually studied. The aim of the study is to assess the environmental safety of the TCs of oil-contaminated soils and drilling waste (microbiological remediation sites). The article describes the methodology of conducting research based on environmental monitoring. The work was carried out on six TCs located in different areas of Perm Region from 2010 to 2020 to study the content of pollutants in air, in surface and groundwater, and in soils. The state of vegetation in the zone of TC influence is described. Based on the results of the research, the environmental safety of the design and engineering solutions adopted during the construction and operation of the TC is justified. It is shown that minimization of environmental impacts occurs in several directions: site selection, topography arrangement and anti-filtration protection. Examples of anti-filtration protection are given depending on geological conditions.KeywordsEnvironmental monitoringEnvironmental safetyOil waste disposalMicrobiological remediationAnti-filtration protection
