Abstract
This work reports the analysis of the efficiency and time of soil remediation using vapour extraction as well as provides comparison of results
using both, prepared and real soils. The main objectives were: (i) to analyse the efficiency and time of remediation according to the water and
natural organic matter content of the soil; and (ii) to assess if a previous study, performed using prepared soils, could help to preview the process
viability in real conditions. For sandy soils with negligible clay content, artificially contaminated with cyclohexane before vapour extraction, it
was concluded that (i) the increase of soil water content and mainly of natural organic matter content influenced negatively the remediation
process, making it less efficient, more time consuming, and consequently more expensive; and (ii) a previous study using prepared soils of similar
characteristics has proven helpful for previewing the process viability in real conditions.
