Bench-scale evaluation of alternative biological treatment processes for the remediation of pentachlorophenol- and creosote-contaminated materials: Slurry-phase bioremediation
Performance data on slurry-phase bioremediation of pentachlorophenol (PCP)- and creosote-contaminated sediment and surface soil were generated at the bench-scale level. Aqueous slurries, containing 0.05% Triton X-100 to facilitate the soil washing process and to help stabilize the suspensions, were prepared from sediment and surface soil freshly obtained from the American Creosote Works Superfund site at Pensacola, Florida. Excluding PCP, benzo(b)fluoranthene, benzo(k)-fluoranthene and indeno(123-cd)pyrene, slurry-phase bioremediation of highly contaminated sediment (pH adjusted) resulted in rapid and extensive biodegradation (3-5 days to biodegrade > 50% of targeted compounds) of monitored constituents. Data suggest that slurry-phase bioremediation strategies can be effectively employed to remediate creosote-contaminated materials.
