Abstract
Approximately 15000 L of unleaded gasoline werereleased into the surrounding vadose zone from aleaking underground storage tank. Initialremediation was by soil vapor extraction andcombustion which soon became cost prohibitive, asadded propane was required to reach the combustionlimit of the extracted vapors. As a cost effectivealternative, a field-scale compost based biofilterwas used in conjunction with soil vapor extractionto remediate the vadose zone. The biofilter wasconstructed on site using 4:1 diatomaceousearth:composted horse manure. Results of a fivemonth study showed that the biofilter removedapproximately 90% of total petroleum hydrocarbons(TPH) and >90% of the BTEX compounds (benzene,toluene, ethylbenzene, xylene), achieving thestringent permit requirements set at either 90% TPHreduction or less than 1.36 kg per day of volatileorganic compounds (VOC's) released to theatmosphere. The biofilter showed the capacity toreadily adapt to changing environmental conditionssuch as increased contaminant loading, andvariations in temperature and moisture. Thebacterial population in the biofilter was uniformlydiverse throughout the biofilter, suggesting that aconsortium of bacteria was needed for efficientbiodegradation. The cost of biofilter set up andoperation saved 90% in the first year alone of theoperating expenses incurred by soil vapor extractionand combustion.
