A relation-analysis-based approach for assessing risks of petroleum-contaminated sites in Western Canada

Effective reflection of and coping with uncertainties are essential for generating reliable risk assessment outcomes. In this study, an integrated risk assessment approach was proposed for assessing environmental risks associated with contamination of multicomponent petroleum hydrocarbons. The approach consists of (a) predicting contaminant flow and transport through a multiphase multi-component numerical modelling system; (b) using …
