Citation:
Shoemaker, J., P. Grimmett, AND B. Boutin. PFOA and PFOS: Analytics. Small Systems Webinar Series, NA, September 27, 2016.
Impact/Purpose:
The purpose of the presentation is to provide an overview of EPA drinking water Method 537 to the Small Systems webinar participants. The presentation describes the drivers for development of Method 537, the extraction and analytical procedure, performance data, holding time data as well as detection limits.
Description:
EPA Method 537 was developed for the analysis of perfluoroalkyl acids (PFAAs) in drinking water to address the occurrence monitoring needs under EPA’s Unregulated Contaminant Monitoring Regulation (UCMR). The method employs solid-phase extraction with analysis by liquid chromatography/tandem mass spectrometry (LC/MS/ MS). This presentation will describe the challenges associated with developing an analytical method for 14 PFAAs as well as demonstrate Method 537 performance data.
