Abstract

Though microbial degradation of mineral oil and its products is well known since a long time, this property of bacteria has not been used till now for the decontamination of oil spills in the subsurface. Usually the polluted soil will be transported in deposits and the polluted groundwater is pumped until oil in phase cannot be detected. A real decontamination should lead to the mineralization of the oil products. A case of such a successful decontamination of an oil-polluted aquifer in an industrial area by microbial degradation were optimized by adding growth factors (e.g., phosphate, ammonia, etc.) to the groundwater and uncontaminated water from a lower aquifer was injected to protect the non-polluted aquifer, so no oil polluted water could leave the contaminated area. A removal of about 17 tons of mineral oil within 1 1/2 years of operation could be achieved by this method. Based on this example considerations on the decontamination of aquifers polluted with other chemicals are given.
