Abstract Application of fungal‐based bioaugmentation was evaluated for the remediation ofcreosote‐contaminated soil at a wood‐preserving site in West Virginia. Soil at the site containedcreosote‐range polycyclic aromatic hydrocarbons (PAHs) at concentrations in some areas thatexceed industrial risk‐based levels. Two white‐rot fungi ( Pleurotus ostreatus andIrpex lacteus ) were evaluated for remediation effectiveness in a two‐monthbench‐scale treatability test. Both fungi produced similar results, with up to 67.3 percent degradationof total PAHs in 56 days. Pilot‐scale testing was performed at the site using Pleurotusostreatus grown on two local substrate mixtures. During the 276‐day field trial, total PAHs weredegraded by up to 93.2 percent, with all individual PAHs except one achieving industrial risk‐basedconcentrations. It was recommended that fungal‐based remediation be applied to all contaminated soil atthe site. © 2002 Wiley Periodicals, Inc.
