[en] The reclamation of older sour gas plants in western Canada poses a number of problems as past production and waste management practices were not well documented, leading to a concern about possible soil and groundwater contamination. The Turner Valley Gas Plant, the oldest sour gas plant in Alberta, was examined as a site for an industrial museum. Production methods and waste disposal techniques were researched and documented, areas of environmental contamination were located and sampling regimes were established, and a site redevelopment concept was developed that would be sensitive to tourism needs, environmental concerns and reclamation requirements. Data were derived from government and company archives, airphotos, site visits, and interviews with former employees. A number of specific areas on the site requiring reclamation were identified, including areas where likely soil contamination with sulfur, hydrocarbons, mercury, polychlorinated biphenyls, or chromate exists. Methods that can be used to remediate soils and groundwater at the site at low cost are presented. The viability of an industrial museum is supported, with recommendations that the existing buildings be reused, the site be revegetated to reduce heat and dust, that underground hazards such as pits and tanks be buried, and visitor interest be encouraged. 49 refs., 32 figs., 2 tabs
