Salt pollution of surface water in oil fields of Khanty-Mansi Autonomous Area-Yugra

Abstract

The article gives the results of analysis of salt pollution at deposits of Khanty-Mansi Autonomous Area-Yugra (KhMAO-Yugra) based on data of regional hydrochemical monitoring. Data of a twenty-year observation series were used to identify the most polluted water bodies and to determine deposits with the largest salt load. Correlation and regression analyses are used to assess the interrelation between technogenesis characteristics and pollution level. It was found that the current salt pollution in the area is lower than that in the 1990s, though the pollution level has increased at some deposits of the Ob–Irtysh interfluve.
