The talk highlights the use of phytoremediation in Northeastern BC to remediate heavier end petroleum hydrocarbons (i.e., more recalcitrant compounds). An overview of site conditions (location, soils), regulatory requirements and client needs will be discussed along with the remedial option selection process. Several different plant species were planted to determine if one or more species was better suited to the contaminants and the climate. One of the projects goals was to use the information gathered from this project to determine if phytoremediation would be an effective remediation technology at similar land farms owned by the client.

Data collection, observation and experience has been instrumental in understanding the significance of the vapor intrusion pathway and for informing guidance. This presentation will cover twenty years of data collection that provide insight on data correlations, attenuation factors, importance of fate and transport processes, and site factors.
