Lab Standards Workgroup
To provide guidance and testing standards for laboratories performing PFAS analysis for the State of Michigan.
This workgroup consists of lab staff working on PFAS analyses within the Department of Health and Human Services (MDHHS) and Department of Environment, Great Lakes and Energy (EGLE). With funding provided by the legislature, EGLE worked with MDHHS to develop capabilities at the EGLE lab, so that by September 2019, EGLE was able to analyze PFAS drinking water samples using United States Environmental Protection Agency (EPA) Method 537.1. This workgroup also:
- Developed a checklist of critical elements for a PFAS drinking water laboratory report.
- Developed an example drinking water laboratory results report format.
- Developed a public facing FAQ that is on the MPART Web site.
- Conducted a method comparison review of EPA Method 537 Rev. 1.1 and Method 537.1.
- Reviewed draft EPA Method SW‑846 8327.
- Workgroup members commented on all of the sampling guidance documents posted on the MPART Sampling Guidance page.
- A guidance document will be created comparing the State of Michigan laboratories testing capabilities, including testing materials like sample containers, testing methods and analyte lists, and test results reporting. Additional published testing methodologies will be evaluated as they are released to the public for use, including newly released EPA Method 533.
- Workgroup members with EGLE’s Laboratory Certification Program are currently evaluating and certifying laboratories for PFAS testing in drinking water following EPA Method 537.1 in preparation for Michigan’s drinking water rule promulgation.
- Additional testing development studies are being done using EPA SW-846 Method 8327 for groundwater, surface water, wastewater and solids, as well as studies on additional PFAS analytes, and potential testing interferences like high concentrations of iron.
Timeline of Accomplishments:
- November 2018: The State of Michigan begins testing PFAS in ground and surface waters using Isotope Dilution testing methodology.
- September 2019: EGLE Drinking Water Laboratory begins offering PFAS residential test kits for $290/at competitive prices.
- October 2019: The State of Michigan begins testing PFAS in drinking water by EPA Method 537.1.
- April 2020: EGLE finished two educational videos to support the EGLE drinking water residential test kits.
