Abstract

The objective of this research was to evaluate the transport and biodegradation of a NAPL (hexadecane) in layered soil. The results indicate that there was limited removal of hexadecane from soil by pumping. Biodegradation of hexadecane occurred throughout the reactor that was amended with nitrogen and phosphorus. Enhanced biodegradation of hexadecane at the soil textural interfaces was not observed. Bioremediation systems located in layered soil must be carefully designed to encourage complete remediation throughout the contaminated zone.
