The Land Reclamation Division, Alberta Environnment, was asked to reclaim an industrial sewage lagoon in the County of Leduc under the Land Reclamation Program. Data showed the lagoon sludges to contain low levels of contaminants considered to be moderately hazardous. Landfarming was selected as the most cost effective method of rendering the sludge non-hazardous. Extra safety precautions were taken to protect workers on site.  During the planning phase, the chemical characteristics of the sludge, and the precautions required to protect workers, were considered to be the major obstacles to success. However, the physical soil characteristics created by the sludge caused the greatest reclamation problems.
