Amy Wilson, PhD, PE
Technical Director-Environmental, Construction and Remediation
Amy Wilson is a civil engineer and hydrogeologist with over 20 years of engineering consulting experience. Amy’s focus is on groundwater and soil vapor remediation; contaminant fate and transport; conceptual site/hydrogeologic modeling; numerical modeling; water quality; and feasibility analyses, with an emphasis on developing technical solutions for large-scale, complex sites. Amy has directed and served as technical advisor for cleanup sites throughout California and other western states, and she is currently focused on developing management strategies for contaminants of emerging concern. Amy holds BS and MS degrees in Civil Engineering from Lehigh University in Bethlehem, PA, and a PhD in Civil/Environmental Engineering from the University of California at Berkeley.
PFAS (per- and poly-fluoroalkyl substances) are a diverse group of man-made chemicals that were developed to be resistant to heat, water, and oil. PFAS have historically been produced for widespread uses such as carpeting, apparel, firefighting foams, and metal plating, and are likely to be found at refineries, military bases, airports, landfills, sludge/biosolids land application sites, fire training facilities, rail yards, chemical facilities, plating facilities, and semiconductor manufacturing facilities. PFAS have been detected at concentrations above state standards and EPA Health Advisory Levels in public water systems throughout the United States. They are widespread globally, and have been detected even in remote places. The toxicology of PFAS is only beginning to be understood. Their persistence, ability to transport, and resistance to typical natural attenuation processes are of increasing concern. The demand for PFAS testing and analysis has increased, and the ubiquitous presence of PFAS presents both a sampling challenge and an important consideration in source attribution. This presentation will provide a broad overview of the various issues and most up-to-date information associated with PFAS, including its unique chemistry, history and sources, toxicology, fate and transport, sampling and analytical challenges, Federal and state regulatory status, and remediation and treatment issues associated with PFAS' complex properties.
