Abstract:

The Keele Valley Landfill at Maple, Ontario, consists of a 99 ha (245 acre) facility to serve the Metropolitan Toronto area. The landfill is located in a former sand and gravel pit, with the base and the sides of the pit being lined with at least 1. 2 m of low plasticity clay till compacted to achieve the required hydraulic conductivity equivalent to 1 multiplied by 10** minus **8 cm/s or less. This paper describes the quality assurance monitoring for the liner construction, including the results of laboratory hydraulic conductivity tests on Shelby tube samples extracted from the liner and the results of a comprehensive program of monitoring the in situ performance of the liner. Results of monitoring to date indicate that the liner is performing as required and good agreement between the results of laboratory testing and in situ liner performance monitoring have been obtained.
