Environmental EIT, PFAS Technical Team
Arcadis
Dr. Johnsie R Lang’s current and past research areas include solid waste, per- and polyfluoroalkyl substances (PFASs), and harmful algal blooms (HABs). Her previous publications demonstrate her work on a national estimate for PFAS release from U.S. municipal landfills to wastewater treatment plants and PFAS release with time from carpet and clothing in model anaerobic laboratory-scale landfill reactors. She holds a Ph.D. in civil engineering from North Carolina State University (NCSU) with PFAS release from municipal solid waste and landfill leachate as her dissertation topic and a Master of Science degree in environmental engineering from NCSU with sulfate leachate from construction and demolition (C&D) waste fines as her thesis topic. Dr. Lang served as a postdoctoral fellow at the United States Environmental Protection Agency (USEPA) for three years studying the toxicology of HABs and PFASs in vivo. Dr. Lang has extensive expertise in laboratory testing of PFASs such as chemical test methods, sample handling and storage, and best practices related to sample collection and analysis. She has experience in PFAS analysis using several different types of test methods and is well versed in selecting specific test methods for sample analysis. Dr. Lang’s previous work alongside chemist and toxicologist in parallel created excellent knowledge of the properties of chemical compounds initiate adverse effects in mammalian systems.
