6 Isolation and use of indigenous bacteria for bioremediation of soil from a former wood treatment site in southwestern alaska

摘要

A temporary wood treatment site located at the University of Alaska Fairbanks (UAF) Palmer Research Farm, Point macKenzie Agricultural Project was operated during the summer months of 1988-1989. An underfine mixture of diesel fuel, creosote, and pentachlorophenol (PCP) was used in the process. Approximately 75 m~3 (98 yd~3) of soil were comtaminated with up to 13.5 ppm PCP, creosote, and 13,000 ppm diesel range hydrocarbons. The Alaska Department of Environmental Conservation (ADEC) established clean-up levels of 0.5 ppm for PCP, and 1000 ppm for diesel range hydrocarbons. The contaminated soil was exavated and stored on site in lined cells pending selecton and implementation of a remoediation method.
