Bioremediation Applications The Nova Group, U.S. Navy Craney Island Fuel Depot Portsmouth, VA
OPERATION DESCRIPTION: Contractor to enhance remediation process of 200,000 to 300,000 tons of oil contaminated soil. 1,000 x 600-ft. cell will treat 17,000 to 30,000 tons of material per season cycle. Soil contamination is from 100 to 20,000 ppm. Must be lowered to less than 1000ppm. This project did NOT required the addition of bacterial cultures. The Brown Bear 500 has maintained moisture and aerobic conditions with various combinations of fertilizers, enzymes and wood chips/straw. The result of the project was a reduction in contaminant level from 21,000 ppm to less than 100 ppm in 83 days. YWC Midwest - North Canton, OH
Key to the innovative method of reducing petroleum-based contamination is addition of manufactured bacterial cultures to soil windrows and frequent machine aerating to maximize natural digestion of organic contents. Expected costs and project time were cut 50 to 75 percent, and the resulting material met all environmental standards for reuse in refinery tank farming, filling and other applications. No incineration, transportation or landfilling of materials was necessary, and imported material needs also were reduced. Savings ranged up to $200 per ton for hazardous soils. The Brown Bear 500 tractor was able to auger up to 3,000 cubic yards of soil per hour, achieving faster decomposition.
