The problem of hydrocarbon pollution of geological environment is particularly acute when it occurs in residential areas. In one area of the Ural Mountains, an oil spill from a gas station resulted in the contamination of groundwater and surface water used by residents of a local village for private water supply. The complex geological and hydrogeological structure of the site exacerbates this situation. An aquifer occurs in a fractured zone of Paleozoic granodiorites complicated by tectonic faults. The main objective of this study is to identify the most optimal methods for investigating the contaminated site in the fractured zone to further substantiate technical solutions for extracting oil products from the underground space. The integrated studies presented in this article provided data on the distribution of oil product pollution, sufficient to substantiate fundamental technical solutions for localizing and eliminating its source. Based on the results of the study, four basic methods for remediating the contaminated site were identified. These include: pumping out the liquid petroleum products; intercepting contamination before the discharge zone into a surface water body using a drainage gallery; extracting petroleum vapors in the aeration zone; and cleaning contaminated reservoir bottom sediments. These technical solutions were proposed as the most effective, taking into account the existing geological and hydrogeological structure of the study area and the presence of residential development within the contamination zone.
