 “I am interested in doing research in subsurface transport and remediation because I want to contribute to solving significant Canadian environmental issues. It is a great experience to be a part of RESTORE because I am surrounded by researchers who are not only talented but who always have friendly encouragement and advice.”

Project Title:
Wettability Characterization for Diesel Fuels.

Project Description:
The project Stephanie is involved with focuses on wettability and NAPL (Non-Aqueous Phase Liquid) contamination in the subsurface. Wettability is a parameter that governs transport and distribution of NAPL contaminants in the subsurface. Current remediation technologies are not always efficient and this is in part due to subsurface complexities (such as non-ideal wettability) that are not accounted
for. While past wettability research has primarily involved idealized conditions, the goal of this study is to investigate the differences between the wettability behaviour of idealized systems and that quantified for real world NAPLs. This was accomplished by examining wettability at three different scales: pore scale, interface scale and
representative elementary volume (REV) scale for a pair of analogous NAPLs. This multifaceted analysis aims to provide a detailed investigation into the causes and implications of field NAPL wettability. This information can ultimately be used to improve numerical modelling and development of remediation techniques.

Personal Background:
While growing up in a small town in Central Alberta, Stephanie was always environmentally conscious and interested in issues regarding the environment. Stephanie came by her interest in math and physics honestly since both her parents are engineers and when she discovered that Environmental Engineering was an option for post-secondary education it seemed like a perfect fit. While getting a Bachelors of Environmental Engineering from Carleton University, she found her favourite courses were those dealing with contaminant transport and groundwater flow. Upon graduation in 2008 she decided to pursue research in groundwater contamination to help contribute to solving environmental concerns in Canada and around the world.
