Title: Bench-scale solid phase biotreatment: Benfield Industries Superfund site

Abstract

The Benfield Industries, Inc. Superfund site located in Hazelwood, North Carolina has been found to have approximately 15,000 cubic yards of polycyclic aromatic hydrocarbon (PAH) contaminated soil. Risk based clean up goals were specified at the site for eight target PAH compounds including benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene, indeno(1,2,3-cd)pyrene, naphthalene, and pentachlorophenol. Treatability studies were performed to evaluate solid phase bioremediation, which includes ex-situ and in-situ land treatment processes, for treatment of the site soil. All treatments were conducted using only indigenous microorganisms maintained under aerobic conditions. Two soil samples with different levels of PAH contamination were collected from the site for use in the treatability evaluations. The two soil samples were contaminated with total PAHs at concentrations of approximately 30 milligrams per kilogram (mg/kg) and 6,000 mg/kg, respectively. Three solid phase bioremediation studies were conducted over a one and one half year period using starting concentrations of total PAHs of approximately 30; 600; and 6,000 mg/kg. The objectives of the studies included determining (1) if clean up goals could be achieved, (2) the approximate biodegradation rate of PAHs in the site soils, and (3) the optimum environmental conditions for biodegradation of the PAHs. Some of the environmental parameters whichmore » were varied during the testing included moisture levels, soil conditioners, nutrients and pH. The results of the testing indicated that total and target PAHs can be reduced by up to 90 percent in less than 50 days, depending on environmental conditions maintained in the reactors. Clean up goals for all of the target compounds were achieved at some point during the study.« less
