Development of complex and efficient technologies for remediation of contaminated soils (NRDP-3/002/2001)
Duration: 2001-2004
DEVELOPMENT OF COMPLEX AND EFFICIENT TECHNOLOGIES FOR REMEDIATION OF CONTAMINATED SOILS
During the 3-year research activity we have focused on the design and selection of the best biotechnology for remediation of contaminated soils. One of our main goals was to develop in situ bioremediation technologies competitive with the physico-chemical soil treatments concerning efficiency, time requirement and cost.
The microflora of contaminated soils, the adaptation of fungi and plants accumulating the inorganic microcontaminants, as well as the processes of the natural biodegradation and bioaccumulation have been thoroughly studied using our "Soil Testing Triad" methodology, which integrates physico-chemical, biological and ecotoxicological methods. A new concept, the so called „reactor concept” was introduced for classifying the soil remediation technologies.
It was proved in laboratory and field experiments that the best way to improve the efficiency of the natural bioremediation is to ensure optimal conditions for the existing and already adapted biological system: in case of biodegradation by proper ventilation, by nutrition supply, by bioavailability-enhancing additives, in case of phytoremediation by using mycorrhizae–plant symbiotic associations, and by applying chemical stabilizing agents. The selected additives and different plant-fungi pairs were tested in field experiments at four contaminated sites. For the best combinations of technologies patent applications and know how were compiled.
The scientific fundament of the ecoengineering concept concerning contaminated soils and in situ bioremediation has been established. A new efficient methodology of cost – benefit analysis has been elaborated. Not only the measurable benefits, but the risk reduction as a benefit was also evaluated. The different bioremediation technologies in general and the site-specific technologies at the four contaminated sites were evaluated by SWOT analysis.
