Report

On August 16, 2019, EGLE released the report describing the findings from the 2018 PFAS Sampling of Drinking Water Supplies in Michigan. The report consists of the main body and four appendices. 

• 2018 PFAS Sampling of Drinking Water Supplies in Michigan (pdf) - This is the main body of the report. With the exception of the overview of Appendix A, all Appendices have been separated out.
• Appendix A - Quality Assurance and Quality Control (QA/QC) Summary (pdf).
• Appendix B - Heat Maps of 2018 PFAS Sampling Program by County (pdf).
• Appendix C - Analytical Laboratory Reports. The 1,877 individual lab results for each public water supply were sent to each supply with their results letter.  You may also contact EGLE's Freedom of Information Act coordinator regarding these reports.
• Appendix D - Validation Reports. This appendix consists of the detailed QA/QC reports completed for 20% of the overall collection effort. Contact EGLE's Freedom of Information Act coordinator for these reports.

Overview

The initial phase of statewide PFAS surveillance testing began in April 2018, and was originally conceived as a multi-year project covering drinking water for approximately 75% of Michigan’s residents. This effort initially included community water supplies, schools on their own well(s), and water supplies for Michigan’s federally-recognized tribes who chose to participate in this survey. In November 2018, sampling was expanded to also include child care providers and Michigan Head Start programs on their own well(s). Testing was ultimately done for the following supplies:

• 1,112 Community Water Supplies (CWS)
• 459 Schools on their own wells
• 152 Daycares and MI Head Starts
• 17 Tribal water systems

This sampling was completed in December 2018. Therefore, approximately 7.7 million of Michigan's 10 million residents have now had their drinking water tested for PFAS. The results of this testing are detailed in the interactive tables below. A summary report of the overall results is available to the right.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has provided recommendations based on PFAS levels. View this notification protocol (pdf).

Beyond Phase I:

• Phase II of the Statewide PFAS Sampling Survey
• Quarterly PFAS Monitoring Program
• Monthly PFAS Monitoring Program for Michigan’s Surface Water Supplies, including the Great Lakes
