Appendix_D_-_Methods_with_Reporting_Requirements.xlsx

This document is an Excel spreadsheet listing analytical test methods and reporting requirements for per- and polyfluoroalkyl substances (PFAS) chemical analysis. It includes 17 methods for analyzing PFAS compounds in various matrices like tissue, soil, water, and biological samples. The methods include EPA Methods 1633, 1633-M, 537.1, and various custom methods developed by AXYS Analytical Services. For each method, the spreadsheet requires information like the analytical test provided, applicable compound CAS numbers, description of items, proposed method numbers, laboratory method names, modification status, method detection limit study dates and results, reporting limits, acceptable proficiency test dates and providers, and corrective actions for failed analytes.

The related federal contract opportunity is a solicitation from the US Geological Survey Office of Acquisitions and Grants seeking PFAS chemical analytical services. The number is 140G0223R0012 and is titled "PFAS Chemical Analytical Services". The spreadsheet appears to be a template for contractors to provide details on their laboratory test methods and reporting capabilities to support this solicitation for PFAS analysis.
