Leah MacKinnon, M.A.Sc., P.Eng.
Leah MacKinnon is a Senior Principal Engineer with more than 20 years of professional experience in Canada, the United States, and Europe focusing on remediation of groundwater containing recalcitrant and emerging compounds using innovative in situ technologies.
Leah has directed, managed, and provided specialist technical support in applied chemistry in the subsurface environment for projects including overall strategy development; site investigation; laboratory treatability studies; and remedial selection, design, and implementation.
Her technical experience involves dense non-aqueous phase liquid (DNAPL) fate and transport in porous and fractured media; site investigation; and the design, implementation and interpretation of in situ remediation technologies to treat contaminants including chlorinated solvents, perfluorinated compounds, pharmaceuticals, pesticides, and metals. Leah's remediation technology experience also includes in situ chemical oxidation, enhanced in situ bioremediation, phytoremediation, in situ alkaline hydrolysis, surfactant flushing, reductive dechlorination using zero-valent iron, and monitored natural attenuation.
To advance the state of the practice, Leah has been a pioneer in the development and application of sequenced remedial technologies to provide cost-effective solutions, particularly at sites where challenging contaminant mixtures and geochemical and geologic conditions are present. She is the author of numerous publications and presentations on the development and application of remedial technologies.
