Specifications include, but are not limited to: Method Analysis • Follow EPA 537.1 Modified Isotope Dilution (ID) for Per- and polyfluoroalkyl substances (PFAS) 36 Analytes provided in Table 1. • Presently there is only certification for PFAS in potable water samples (EPA 537.1). Provide documentation to support the precision and accuracy of the Fish Tissue Method, Surface Water Method, and Wastewater influent/effluent Method employed. • Conduct analysis on dedicated PFAS Instruments. Detection Limits Required • Fish Tissue Sample Detection (MDL): Range for 36 PFAS (0.2 - 0.8 ng/g) • Surface Water Sample Detection Limit (MDL): Range for 36 PFAS (0.5 - 2 ng/L) • Wastewater influent/effluent Detection (MDL) Range for 36 PFAS (0.5 - 2ng/L)
