Abstract

Transport of selected creosote compounds and tracers in two column experiments and a field study in fractured clayey till are presented. Twenty-five organic compounds were used in the column experiments and 12 in the field experiment. This paper focuses on three organic compounds: phenol, naphthalene and dibenzofuran. One column was biologically inactive, and the other was biologically active with denitrifying conditions in the beginning and aerobic/denitrifying conditions later on in the experiment. The infiltration water at the field site was aerobic in the beginning and anaerobic (no oxygen, very little nitrate, and some sulphate) later. The results showed very rapid transport through clayey till of the tracers and the organic compounds. Despite the rapid transport through fractures, biodegradation may be an important process in fractured media at least for the easily degradable organic compounds.
