Title:

PFAS Surface Water Sampling [Michigan]

Description:

Surface water samples analyzed for PFAS are collected through EGLE's Water Chemistry Monitoring Program and watershed/source tracking investigations. To learn more about EGLE's effort in sampling lakes and streams for PFAS visit theMPART PFAS Sampling in Lakes & Streams website. Surface water contaminant concentrations are compared against Michigan's Water Quality Standards. Michigan has derived Part 4 Rule 57 water quality values for two PFAS: Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA). The Human Noncancer Value (HNV) for PFOS is 11 parts per trillion (ppt) for surface waters used as a drinking water source and 12 ppt for all other water bodies. The PFOA HNV is 420 ppt for surface waters used as a drinking water source and 12,000 ppt for all other water bodies.Contaminant data often include flags, also known as qualifiers, which are notes attached to data that gives detailed information about that particular result. In the surface water PFAS data layer, PFAS analytes associated with a "K" flag were not detected in the sample and therefore the method detection limit (MDL) is displayed. "J" flagged results indicates an estimated concentration as the result is above the MDL but below the laboratory reporting limit.The number of PFAS analytes EGLE analyzes in surface water samples has increased over the years. EGLE is currently analyzing for 29 PFAS analytes in surface water samples. In the surface water PFAS data layer, if a flag is listed as "Not Measured", that particular PFAS analyte was not included in the analysis for that sample.This data is used in theMPART: PFAS Geographic Information System(item details).
