dc.description.abstractBiosparging enhances both aerobic biodegradation and volatilization, and is commonly applied to residual hydrocarbon source zone remediation. This technology was applied in pulsed mode to a known source of gasoline contamination in order to quantify the extent of remediation achieved in terms of both mass removed and reduction in mass discharge into groundwater. The gasoline source was created by injecting about 40 L of gasoline with 10% ethanol in small volumes from 24 injection points below the water table in 2004. The downgradient plume is still being monitored and the source area was cored in 2007. In 2008, a 3-point biosparge system was operated with an airtight cover to capture and monitor off-gases. Of the hydrocarbons in place, about 80% of pentane, 50% of hexane, but only about 4% of the aromatic hydrocarbons were volatilized and removed. CO2 and O2 monitoring in the off-gas confirmed limited biodegradation of hydrocarbons.
dc.description.sponsorshipThis work was supported by an Ontario Centres of Excellence (OCE) grant and by contributions from Aqua Terre Solutions, Shell Canada Products, Petro-Canada, API Energy, and Solinst Canada. Analytical support was provided by Marianne VanderGriendt and Shirley Chatten and technical support by Paul Johnson and Robert Ingleton. Initial idea discussed with X. Yang. The authors would also like to thank the reviewers of this paper for their suggestions.
