Dr. Jaana Pietari has more than 20 years of professional and academic experience in environmental remediation, the fate and transport of contaminants, the reconstruction of environmental releases to groundwater and sediments, and environmental forensics. She has evaluated the sources and fate and transport of emerging contaminants, such as PFAS and 1,2,3-trichloropropane (1,2,3-TCP); chlorinated solvents; polycyclic aromatic hydrocarbons (PAHs); petroleum hydrocarbons; and polychlorinated biphenyls (PCBs). Dr. Pietari's consulting assignments involve various environmental media, including soil, groundwater, and sediments, in settings from residential properties to urban mega-sites and industrial facilities, integrated steel mills, refineries, petroleum terminals, pharmaceutical manufacturing plants, agricultural chemical distribution facilities, and manufacturing sites. Dr. Pietari has supported clients in identifying and evaluating sources of contaminants, including conducting investigations to identify sources of PFAS in stormwater and in consumer products and the associated manufacturing processes, and in developing strategies to replace PFAS-containing firefighting foams.
