The Geoengineering Centre at Queen's - RMC is undertaking a major collaborative project examining a range of issues related to the long-term performance of geomembranes (GMs) and geosynthetic clay liners (GCLs) used in liner systems for applications such as municipal solid waste landfills and heap leach pads used for resource recovery. A particular focus is on both how long these stems will last and on how well they will provide environmental protection from emerging contaminants of concern. An integrated project team with direct funding from Federal and Provincial agencies and industry and in-kind contributions and collaborations from regulatory and industrial partners is investigating these issues through a combination of field, laboratory and theoretical modelling. Papers arising from this work can be accessed directly from this web page as they are published. Papers in press are also listed but can not be downloaded directly until published.
