Aim. The aim of the work is to analyze the impact of petroleum products saturated with potential toxic elements on the environment within the fragile ecosystems of the Arctic region and calculate the damage to groundwater in monetary terms. Methodology. Use is made of chronological analysis, regulatory and technical analysis of infrastructure compliance with the established requirements, and methods of generalization, interpretation, and mathematical analysis, as well as of interpretation of satellite images for the movement of flowing waters saturated with petroleum products. Results. An environmental impact is assessed, a regulatory and technical analysis of the compliance of infrastructure facilities with current regulatory and technical requirements is carried out, and economic damage from groundwater pollution is calculated in monetary terms. Research implications. The latest environmental disaster in Norilsk is a vivid example of the imperfection of the system of environmental approach in the operation of industrial production facilities. The paper clearly demonstrates the practical importance of ensuring timely technical diagnostics of fuel and lubricant storage facilities. The results of the study will allow scientists and environmental protection workers to assess the consequences of the disaster and use the research materials to justify the elimination of environmental damage. The paper will allow all interested persons to assess the real consequences of the disaster and realize the importance of compliance with all requirements and regulations in the field of environmental protection.
