Abstract A feasibility study of the in situ remediation of a former tank farm (on a petrol station) was made over a period of 150 days at 10 °C. The natural attenuation (which is a sum of the abiotic losses and the natural biodegradation by the indigenous soil microorganisms) and the effect of biostimulation by inorganic nutrient supply were investigated. The contamination was not homogeneously distributed in the seven soil samples investigated. Nutrient addition had no statistically significant effect on hydrocarbon decontamination. A remarkable part of the decontamination had to be attributed to natural attenuation. Soil microbial counts and CO2 evolution indicated a negative effect of nutrition on the number of microbial hydrocarbon degraders and on soil microbial activity.
