Short description: As of March 2017, no standard EPA methods have been developed for analyzing PFAS in groundwater, surface water, wastewater, or solids. Some U.S. laboratories are using modified methods for non-drinking water samples based on EPA Method 537. These modified methods have no consistent sample collection guidelines and have been neither validated nor systematically assessed for data quality. To provide validated methods for sample types other than drinking water to fill this sampling and analytical gap, EPA formed a cross-Agency method development and validation workgroup. The workgroup will develop analytical methods for quantifying 24 PFAS analytes using a phased approach.
