Description

In November 1989, a liquid mixture of various contaminants including the wood preservatives creosote and pentachlorophenol (PCP) was found seeping into the Bow River adjacent to the abandoned Canada Creosote site in Calgary. A temporary berm was built in the river around the seepage area on November 6-9, 1989, and rebuilt on October 9-19, 1990. Contaminants were removed from the bermed area. A permanent barrier to contaminant flow was installed along the entire shoreline between April 29 and May 3, 1995, and a system designed to prevent the flow of contaminated groundwater to the river around the barrier was operational by February 8, 1996.
