BIOTREATABILITY AND FEASIBILITY TESTS FOR A BIOREMEDIATION PROCESS - A CASE-STUDY FOR A KEROSENE CONTAMINATED SOIL

The present paper reports on a multilevel experimental research work c arried out to support an actual in-situ bioremediation of a kerosene c ontaminated site. The remediation project consists in a soil stripping with air followed by a bioventing step to effetc the biodegradation o f the residual non-volatile part of pollutants. The experimental work was aimed at verifying the actual biotreatability of many soil samples taken at different locations and at different depths in the contamina ted site and to investigate the influence of the relevant parameters a nd variations such as: nutrients supply (N, P in different forms) and their optimal amounts, soil pH correction, inoculation with specialise d microflora.
