||Bioslurry treatment of polycyclic aromatic hydrocarbon (PAH)-impacted soils was demonstrated under the Superfund Innovative Technologies Evaluation (SITE)/Emerging Technologies Program (ETD) as an extension of research previously funded by IT Corporation (IT) and additional investigations supported by the U.S. Environmental Protection Agency (EPA). During the demonstration, IT operated two 60-liter (L) TEKNO Associates bioslurry reactors (Salt Lake City, Utah) and a 10-L fermentation unit is semicontinuous, plug-flow mode for a 2-month period. The first 60-L reactor received fresh feed daily and supplements of salcylate and succinate to enhance PAH degradation. During operation, the bioslurry reactor system demonstrated average PAH and carcinogenic PAH (CPAH) removals of 84 and 66 percent, respectively. The reactors will be operated over the next four months to increase the rate and extent of PAH biodegradation. The objective of the demonstration is to illustrate bioslurry treatment of impacted soils and sludges as an effective and economically attractive remedial option.
