Susan B. Welt, M.P.H., P.E.
Oxford Who’s Who has inducted Ms. Susan B. Welt into the highest Professional Distinction “Top Tier of Excellence Lifetime Achievement Recognition” due to her leadership in environmental engineering where she has had the privilege of designing and managing remedial strategies environmentally impacted site projects throughout the world, as well as being one of very few females representing this industry at this expert level. Ms. Welt is one of few special honorees distinguished based on her professional accomplishments, academic achievements, years of service, and the credentials she has provided. Susan Welt has built a reputation as an expert in her field specializing in strategic planning, community relations, and engineering, specifically in the areas of vapor intrusion and manufactured gas plants, as well as development and oversight of company-wide and community health and safety programs, dispute resolution process, and managing complex environmental projects.
Ms. Welt is a Registered Professional Engineer with over 15 years of experience in environmental consulting and regulatory work. She is a recognized expert in the field of vapor intrusion, having evaluated and mitigated vapor intrusion into indoor air at hundreds of major industrial and residential sites. She served as a vapor intrusion expert with the New York State Department of Health, is a former member of the ITRC vapor intrusion team, assisting with the development of the ITRC vapor intrusion guidance document, and has been an invited speaker on vapor intrusion topics. Ms. Welt is an experienced strategic planner and risk communicator, and manager of soil, groundwater, and sediment investigation and remediation projects at industrial sites, former manufactured gas plants (MGPs), mining operations, and Department of Defense facilities across the country. Her MGP experience is broad and includes investigation, evaluation, 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’s practice also focuses on the risk-based management of contaminated sediments and the in situ remediation of sediments and soils impacted by VOCs. She uses a multiple-lines-of-evidence approach to develop applicable soil remediation levels that limit the need for excavation and deed restrictions while also being protective of public health and the environment. Ms. Welt has extensive experience in design engineering, stakeholder negotiations, and management of complex environmental projects. She has participated in the dispute resolution process to ensure that responsible parties implement the appropriate measures to reduce exposures from the soil vapor intrusion pathway and impacted groundwater. She has developed and implemented many forums for discussing the status and rationale for environmental work and the associated human health and environmental risks. Ms. Welt has authored numerous papers and given presentations on a variety of topics including community relations; vapor intrusion sampling, assessment, and mitigation techniques; risk based management of contaminated sediments; treatment of groundwater; and in situ remedial methods for contaminated sediments and soils. She is also a Fellow of the Centers for Disease Control and Prevention Environmental Public Health Leadership Institute. Geosyntec is a specialized consulting and engineering firm that works with private and public sector clients to address new ventures and complex problems involving our environment, natural resources, and civil infrastructure. They focus on helping clients with issues such as contaminated site assessment and cleanup, environmental planning and management, air quality management and air pollution control, water and natural resources assessment, management, and restoration, water and wastewater system planning, engineering, and design. Susan Welt continues to advance as an expert in her field while continuing to provide her clients with the best solutions to their unique problems.
