Abstract

To evaluate the risks concerned with the presence of volatile organic compounds in the unsaturated zone it is important to know how the compounds are transported in the soil. In this project the effective diffusion coefficient of 3-methylpentane, hexane, methyl-cyclopentane, iso-octane and methyl-cyclo-hexane has been measured in-situ using a diffusive tracer test (DTT). Furthermore the flux from a NAPL source has been measured in flux chambers. From these results the effective diffusion coefficient has been calculated for CFC113, methyl-cyclo-pentane, benzene, iso-octane, and methyl-cyclo-hexane, but there is a large variation between these results and the corresponding values from the DTT-experiment.
