Susan's practice focuses on the risk-based management of contaminated media. By using a multiple-lines-of-evidence approach, she has developed remediation action levels that are protective of public health and the environment; including, but not limited to applicable soil remediation levels that limit the need for excavation and deed restrictions, and groundwater clean-up levels based on minimizing the VI exposure pathway.
Her MGP experience is broad and includes site investigation, engineering design, remedial oversight, and site management at many different sites. She has researched various remedial measures to address residual MGP impacts, including development of risk-based remedial goals that incorporate bioavailability for MGP-impacted sediments.
Susan has evaluated and mitigated VI impacts at hundreds of major industrial, commercial, and residential sites throughout the United States and Europe. She previously served as a VI expert with the New York State Department of Health and is a former member of the VI technical team for the Interstate Technology and Regulatory Council (ITRC). In this role, she was a contributor to the ITRC's current VI guidance.
In 2010, Susan became a fellow in the Environmental Public Health Leadership Institute at the U.S. Centers for Disease Control and Prevention. She is a member of the National Society of Professional Engineers, the Association for Environmental Health and Sciences, and the National Air and Waste Management Association.
To advance the state of the practice, Susan is a frequent presenter at industry conferences and symposia. She is the author or co-author of numerous papers on VI sampling, assessment, and mitigation techniques; the risk-based management of contaminated sediments; and the in situ remediation of contaminated sediments and soils.
