[en] A loss of ca 15,000 liters of gasoline from underground storage tanks resulted in contamination of ca 3,000 m³ of soil and formation of a liquid gasoline plume which occupied over 1,000 m² of an aquifer at Carberry, Manitoba. A remediation program was implemented to recover the gasoline from the soils and aquifer in order to contain the gasoline plume and return the aquifer to a usable state. Following installation of several monitoring wells and computer modelling of the plume, a remediation plan was devised. A recovery system was designed and implemented which comprises two water table depression and recovery wells, a hydrocarbon vapor extraction system, and an air stripping tower. Since the start of recovery operations, the subsurface liquid gasoline plume has been reduced to isolated pockets. However, following rain events, gasoline continues to leach from the contaminated soils and move down to the water table, resulting in intermittent floating liquid plumes. The reduction in size of the plume is chiefly attributed to the operation of the recovery system. The vapor extraction system had removed ca 4,000 liters of gasoline, and the ground water system was then able to remove ca 3,000 liters of gasoline from the aquifer. Continued use of the recovery ssystem is expected to remove the recoverable gasoline contamination from the subsurface within the next two years. Residual amounts which cannot practicably be removed will remain and continue to biodegrade over time. 17 refs., 12 figs., 1 tab
