Emily Stockwell is a Professional Engineer with GSI Environmental Inc. with 9 years of experience in environmental consulting. Her expertise includes characterization and remediation of soil and groundwater impacted by organic and inorganic contaminants. Ms. Stockwell has extensive experience evaluating hydrologic, geologic, and chemical data to develop conceptual site models describing the source, migration pathways, transport mechanisms, and potential receptors of contaminants. She coordinates the investigation and characterization of contaminated soil and groundwater using state-of-the-art investigation methods. She selects, implements, and evaluates the effectiveness of remediation strategies, including soil vapor extraction (SVE), multi-phase extraction (MPE), in-situ chemical oxidation (ISCO), enhanced in-situ bioremediation (EISB), zero valent iron (ZVI), and monitored natural attenuation (MNA). In addition, Ms. Stockwell is an expert in evaluating natural source zone depletion (NSZD) at hydrocarbon impacted sites and developed a novel method for monitoring NSZD rates using subsurface thermal fluxes. Ms. Stockwell is also deeply involved in several Department of Defense research and development projects related to characterization, fate and transport, and treatment of per- and polyfluoroalkyl substances (PFAS).
