Abstract
Oil around buildings is sucked under them. The conditions for accumulation of oil exist under engineering constructions. It is necessary to clean oil-contaminated territory, whether it is free from infrastructure or under engineering constructions. Cleaning technology with hydrocarbon-reducing micro-organisms was tested on the site of a tank farm with contaminated soils. The sorbent with micro-organisms placed at a depth of 40–60 cm below the technical buildings has cleaned the oil from the soil. The micro-organisms assimilate the n-alkanes with C14 chains rather than the C32–C40. The oil is destroyed quicker under the constructions than in the open areas.
