||IT Corporation conducted a pilot-scale testing of biological and chemical oxidation of slurry-phase polycyclic aromatic hydrocarbons (PAHs). The 7-month demonstration illustrated potential effectiveness of combined biological and chemical oxidation for the treatment of PAH-contaminated soils. The 80 percent Carcinogenic PAH (CPAH) destruction goal was achieved with CPAH transformation ranging up to 84 percent. A system hydraulic residence time (HRT) of approximately 37 days increased system performance. It should be noted that greater than 80 percent CPAH removal was achieved during the last 2 weeks of operation following modifications to the treatment process made during the previous weeks. These results are reflective of the effectiveness of the treatment system following achievement of steady state operation. Overall, operation of R1 and R2 only was adequate for effective treatment following in increase in HRT.
