Saltwater spill site assessment and remediation in Northern Alberta
MetadataShow full item record
This study focuses on the Alberta environmental site assessment process for salt contamination resulting from pipeline failures in the boreal forest of Alberta. A complex saltwater spill site is used as a case study to determine the effects of various parameters of interest, including electrical conductivity and sodium adsorption ratio. This study reviews the practical efficacy of the Alberta environmental site assessment process to ensure sites meet the legislated requirement for remediation closure in a timely and environmentally sound manner. The study includes a comparison of various parameters of interest on a case study site collected over a three-year period and reviews available remediation alternatives. The study provides a summary interpretation of how the existing regulatory process affects decisions to ensure site decontamination and sustainability of the boreal forest ecosystem where the upstream oil and gas industry operate, and includes recommendations for policy improvement.
