Biopile treatment of hydrocarbon contaminated soil of the Redwater Oil Production Area
MetadataShow full item record
The Redwater Production Area (RPA) is an established oil field located north of Edmonton in central Alberta. Recent assessments indicate that substantial amounts of hydrocarbon contaminated soil exist in the RPA as a result of the use of flare pits, ecological ponds, product spills and pipeline leaks. Alternative remedial technologies may reduce the quantity, cost, and ultimately the long-term liabilities associated with the current practice of landfill disposal. The purpose of this thesis is to assess the viability of accelerated biopile soil treatment as a remedial methodology in the rehabilitation of contaminated soil in the RPA. The thesis includes a literature search, a bench scale treatability and pilot biopile experiment and concludes with a summary of the viability of biopiling to be employed as part of a multi-year/multi-site remedial initiative. Construction of the Redwater Soil Treatment Facility began in 2008 with treatment and recycling operations commencing in early 2009.
