In 2009, the US Environmental Proection Agency issued Method 537 (Version 1.1.) for the determination of selected perfluorinated alkyl acids in drinking water by solid phase extraction and liquid chromatography/tandem mass spectrometry (LC/MS/MS).  Subsequently, PFOA and PFOS, along with 4 other perfluorinated compounds, were added to the third Unlegulated Contaminent Monitoring Rule (UCMR 3) which defines a list of contaminents to be monitored by public water systems and specifies EPA Method 537 as the reference analytical method.  With ongoing risk assessments being completed on perfluoroalkyl substances (PFAS) under the IRIS program.  (Integrated Risk Information System) in the US, analytical testing of environmental samples for PFAS is likely to increase with US EPA Method 537 being an established method for reference or modification.

In response to requests, Wellington Laboratories has prepared support solutions for US EPA method 537 including the surrogate primary dilution standard (EPA-537SS) and the internal standard primary dilution standard (EPA-5371S).
