Creosote-contaminated groundwater contains a complex mixture of phenols, aromatic hydrocarbons and nitrogen-, sulphur- or oxygen-containing heterocyclic, aromatic compounds. One of the most important factors that limits the spreading of these contaminants in groundwater aquifers is degradation by subsurface micro-organisms. This paper gives an overview of the present knowledge about microbial degradation of creosote contaminants under aerobic and anaerobic conditions. Furthermore, various techniques for biological remediation of creosote-contaminated groundwater are outlined. These techniques include enhancement of the native population of subsurface micro-organisms to degrade the contaminants (in situ treatment) and withdrawal of the groundwater followed by treatment by various wastewater treatment processes (above-ground treatment).
