Non-Targeted Analysis: Emerging Contaminant Monitoring at the Bleeding Edge
Citation:
McCord, J. Non-Targeted Analysis: Emerging Contaminant Monitoring at the Bleeding Edge. LCGC Magazine Virtual Symposium on PFAS Analysis, Durham (virtual), NC, March 26 - 27, 2024.
Impact/Purpose:
The talk will discuss ongoing work of EPA ORD in the realm of novel PFAS discovery and non-targeted analysis. Results are of interest to various state/regional partners and members of the broader PFAS research community. Specific case studies of partnerships could lead to future ORD projects with relevant stakeholders and/or provide a template for future efforts by other laboratories.
Description:
Industrial producers and users of per- and polyfluorinated alkyl substances (PFAS) have been a major source of chemical contamination due to historical releases of legacy PFAS. Following the general phase-out of legacy PFAS such as PFOA/PFOS, industrial usage has shifted to alternative PFAS and it has been the domain of non-targeted analysis (NTA) to identify replacement species. As such, over the last several years the office of research and development has applied non-targeted analytical approaches to the analysis of industrial effluent and contaminated environmental media (e.g. groundwater) provided by our state and regional partners to investigate the identity and quantities of legacy and emerging PFAS chemistries. This talk will provide an overview of NTA approaches for PFAS monitoring and identification of emerging PFAS contaminants along with some example case studies.
