Abstract:

The paper presents the results of some microbiological depollution (bioremediation) tests on a site of a decommissioned reservoirs park formerly used for stocking crude oil. For the physical and structural characterization of the site, unpolluted soil samples have been prevailed, and analyzed with regard of the crude oil content [1]. The study presents the methodology of an “in situ” bioremediation technology with regard to the soil preparation, nutrients and oxygen compounds addition, in order to enhance the microbial metabolism [2]. The site was monitored and measures for keeping a high depollution rate were taken. After 20 months, the depollution yield was 60%. The values for pollutants were similar to those accepted for the upper limit of contamination [3]. Economical aspects of bioremediation process, advantages and drawbacks are also discussed.

Keywords:
