Shanna Thompson is a Principal Environmental Engineer based in Georgia with more than 19 years of experience focused on site investigation, remediation design, and remediation system operation. She has performed delineation and remediation at dozens of sites with recalcitrant compounds in soil, sediment, surface water, and groundwater.
Her specialty includes sites listed on the CERCLA Superfund National Priorities List and Georgia Hazardous Sites Inventory (HSI) Sites that are managed under the Hazardous Sites Response Act (HSRA) and Voluntary Remediation Program (VRP) Act. She is also experienced with sites regulated by state programs in Tennessee, Alabama, New Jersey and North Carolina. Shanna recently managed $11M in Environmental Protection Agency (EPA) Superfund site remediation work with the purpose of restoring groundwater at sites that were contaminated from past activities, such as wood treating, dry cleaning, waste management, and electronics manufacturing.
The early portion of her career was spent designing and performing field oversight of contaminated soil removal, remediation injection applications, and remediation system construction. She has particular expertise in the design and application of in situ injections for oxidation and enhanced bioremediation. Shanna was recently involved in testing and advancing microbial remediation cultures that can be deployed to treat sites contaminated with pentachlorophenol and naphthalene from former wood-treating operations.
Shanna led a project team that received an American Council of Engineering Companies (ACEC) Engineering Excellence Honor Award in Georgia in 2017. This project was an evaluation of the potential for vapor intrusion into hundreds of homes and other buildings that are located in proximity to groundwater contamination. The project team evaluated laboratory data from hundreds of indoor air, outdoor air, and soil gas samples to ensure the protection of human and ecological health.
In recent years, Shanna has given technical presentations at the Georgia Environmental Conference, Georgia Brownfield Association Seminar, Alabama Department of Environmental Management’s Annual Groundwater Conference, Conference on Remediation of Chlorinated and Recalcitrant Compounds, and the EPA Region 4 Superfund Team Symposium. She has also been a guest lecturer at Emory University, Georgia Tech, and Clemson University.
Shanna serves as Board of Directors member for the Georgia Brownfield Association. Shanna has served as chair of the Georgia Brownfield Association’s Annual Brownfield Seminar in 2019, 2020, and 2021. In this role, Shanna organizes the efforts of several other leaders to cultivate technical and inspirational content for this day-long meeting of approximately 200 engineers, lawyers, scientists, regulators, and community activists to highlight redevelopment of contaminated land that resolves exposure risks, stimulates local revitalization, and is mindful of environmental justice.
