Speaker profile
Elizabeth Denly
Ms. Denly leads the TRC Center of Research & Expertise (CORE) PFAS Team, a group of scientists devoted to staying informed of current PFAS issues, science, and regulations. Elizabeth Denly serves as TRC’s per- and polyfluoroalkyl substances (PFAS) Initiative Leader & Chemistry Director. As a project QA chemist at TRC, Ms. Denly is responsible for providing QA/quality control (QC) oversight in support of different environmental investigations, including remediation programs, ambient air monitoring, and human health/ecological risk assessments.
She currently works on many different types of PFAS investigations with a specific focus on chemistry, sampling procedures, data interpretation, forensics, QA/QC, and analytical methodologies. She has recently collaborated with laboratories on research activities including (1) evaluation of the leachability of PFAS from environmental sampling products; (2) evaluation of analytical approaches (isotope dilution liquid chromatography/dual mass spectrometry, total oxidizable precursor assay, and total fluorine) on samples collected from aqueous film forming foam sources and paper mill sources; (3) evaluation of the solubility of perfluorooctane sulfonic acid; and (4) evaluation of sampling/analytical approaches for the measurement of PFAS in ambient air.
Ms. Denly has also served on advisory committees related to analytical methodologies for the Massachusetts Department of Environmental Protection. Her major areas of expertise include emerging contaminants, data evaluation, quality assurance project plans, data usability assessments, field and laboratory audits, and consulting for regulatory agencies. Ms. Denly has a BA in chemistry from the University of New Hampshire and is a Certified Manager of Quality/Organizational Excellence from the American Society of Quality.
Ms. Denly received the 2017 & 2022 Member of the Year awards for her contributions to the Interstate Technology & Regulatory Council (ITRC) PFAS Team.
