In situ bioremediation of creosote- and pentachlorophenol-contaminated groundwater at a wood-treating site

摘要

The objectives of this multi-year project were to investigate in situ biological remediation for the clean-up of organic wood preservatives in groundwater at a wood treating site. A suitable site was selected at a south Mississippi location where creosote components and pentachlorophenol (PCP) were present in both the groundwater and subsoil. Three temporary recharge wells werre established in the upgrade and in the same screening zone as the recovery well. A bacterial culture, previously isolated and known to efficiently degrade PCP and polycyclic aromatic hydrocarbons (PAHs) (Arthrobacter sp.), oxygen (supplied as 0.005
