Abstract The article presents the results of a study of chemical pollution of landscape components (soil water and groundwater, soils and indicator species of plants) under the influence of drill cuttings dumping onto the soil surface. The studies were carried out in the forest-tundra zone of Western Siberia in two areas for two years after pollution. The lateral and radial differentiation of chemicals was studied. The dynamics of chemical pollution of water, soil and plants was shown. The extent and geochemical zoning of secondary technogenic halos are revealed. The role of geochemical barriers in reducing the migration activity of pollutants was emphasized. The main indicators of pollution, to which Sr, Ba, Na, V, Cr, Fe, Cl − , NO 3 − are attributed, are substantiated.
