Dense Nonaqueous Phase Liquid(DNAPL) Dissolution in Systems with Non-Water Wet Porous Media.

Subsurface wettability is an important propertythat impacts our ability to accurately characterize dense nonaqueous phaseliquid (DNAPL) source zones. Its variability creates uncertainty in predictionsof the fate of DNAPLs in the subsurface. This study is part of a largerinvestigation into the impacts of spatial wettability variations on DNAPLmigration, entrapment, and dissolution. The purpose of this part of the studyis to explore DNAPL dissolution and assess the predictive capability of awettability modified version of the numerical simulator MISER (Michigan SoilVapor Extraction Remediation Model). The influence of source zone architectureon measured and simulated downstream PCE concentrations and associated massflux for this mixed-wettability system is explored to determine the impacts ofspatial wettability variations on DNAPL dissolution.

Personal Background

I graduated from The University of WesternOntario in 2008 with a Bachelor of Engineering Science (B.E.Sc.) in civil andenvironmental engineering. The majority of my undergraduate courses wererelated to the field of environmental engineering. The challenges andopportunities associated with environmental engineering influenced my decisionto attend The University of Western Ontario as a graduate student. I joined theRESTORE team in September 2008 as a Master’s (M.E.Sc.) student.
