Title: The Effect of Age on Petroleum Hydrocarbon Contaminants in Soil For Bioventing Remediation
Author: Xiao, Mei; Zytner, Richard G.
Department: School of Engineering
Abstract: An investigation was completed to determine the effects of petroleum contaminant aging in bioventing, a low cost and non-destructive in situ remediation method. Wet soil spiked with a known concentration of synthetic gasoline was aged in a refrigerator for 300 days and then subjected to degradation tests in 150 g respirometers and an 80 kg bioventing reactor. After aging, the 80 kg reactor had degradation rates that varied from 0.12 d^(-1) to 0.133 d^(-1). In the 150 g respirometer, the biodegradation rate increased from 0.079 d^(-1) to 0.194 d^(-1). Comparison with previously completed dry aged soils, where the biodegradation rate was measured to be 0.053 d^(-1), showed that microbial acclimatization during the wet aging process played a key factor in the experiments.
