Slurry-phase biological treatment of polycyclic aromatic hydrocarbons in wood preserving wastes
- OHM Remediation Services Corp., Findlay, OH (United States)
The Southeastern Wood Preserving site is an abandoned wood preserving facility that was in operation from 1928 to 1979. The US Environmental Protection Agency (USEPA) initiated an emergency response action at the site in June 1986, and excavated approximately 10,500 cubic yards of sludge and contaminated soils from lagoons, treatment facilities and storage areas. The lagoon material was considered to be bottom sediment and sludge from the treatment of wastewaters from wood preserving processes using creosote, and was classified as a Resource Conservation and Recovery Act (RCRA)-listed waste number K001. The excavated materials were stabilized with kiln dust and stockpiled on-site for further treatment. Polycyclic aromatic hydrocarbon (PAH) concentration in the stockpiled soil ranged from 8,000 mg/kg dry-weight to 15,000 mg/kg dryweight for total PAHs and from 1,000 mg/kg dryweight to 2,500 mg/kg dry-weight for carcinogenic PAHs. Treatment criteria were best demonstrated available technology (BDAT) cleanup criteria for RCRA K001 waste, but based on laboratory, pilot and full-scale system performance, a treatability variance was obtained. The treatability variance established the cleanup criteria at 950 mg/kg dry-weight for total PAHs and 180 mg/kg dry-weight for benzo(a)pyrene-equivalent carcinogenic PAHs.
