Using Laser Induced Fluorescence (LIF) to Establish Monitoring Well Network of Migrating LNAPL Plume in the Vicinity of Surface Water

摘要

The former Michigan Avenue Landfill (now Canatara Park) was used by the City of Sarnia for disposal of municipal waste between approximately 1930 and 1967. Between approximately 1930 and 1944, oily waste was reportedly disposed of at the site from one of the local refineries. This waste material was reportedly a by-product of a process that used clay to remove colour impurities during the production of automobile lubricating oil. In 1997, light non-aqueous phase liquid (LNAPL) was discovered at the southwest shore of Lake Chipican, north of the former landfill. In response, temporary measures were taken by the city to contain and collect the oil film at the lake. In 2000, remedial measures were developed to mitigate the discharges from former Michigan Avenue Landfill including installation of a 70-metre-long sheet-pile barrier wall along the south shore of Lake Chipican and installation of two oil recovery wells south of the barrier wall.
