Michigan Adds 19 PFAS Contaminated Sites to List

In a continuing trend, another 19 sites with PFAS contamination have been added to the latest list of Michigan sites. The newest Michigan EGLE PFAS Map Tracker shows that the number of confirmed PFAS contaminated sites has grown to 93, up from 74  in December 2019 and 52 a year ago.  The latest list of PFAS contamination includes sites spread across Michigan, throughout both the lower and upper peninsulas, in rural, suburban, and urban areas The EGLE also provides a PFAS map viewer, which provides information on the site name, location and address, description of the site, and a link to site-specific background, data, PFAS contaminants, site history, and recent activities.

Michigan’s Minimum PFAS Analyte List Grows

Four new compounds have been added to the State of Michigan’s minimum laboratory PFAS analyte list, bringing the total to 28. The list is maintained by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) for the testing of drinking water, groundwater, surface water, wastewater, soil, and landfill leachate.

Michigan Sets New PFAS Health Screening Levels for Drinking Water

Michigan Sets New PFAS Health Screening Levels for Drinking Water

The State of Michigan has lowered the drinking water health screening levels for PFAS. These new levels replace the federal advisory guidelines of a combined 70 ppt for PFOA and PFOS that the state had been using since January 2018.

Deploying Drones to Search for PFAS Contamination at Camp Grayling

The Michigan Department of Environmental Quality (MDEQ) is deploying drones to fly over Lake Margrethe to search for cold water springs that could be carrying PFAS contamination into the lake near Camp Grayling.  The MDEQ believes this is the first-ever usage of drones to search for PFAS contamination.

PFAS Soil Site Investigation Efforts Becoming Increasingly More Important

PFAS Soil Site Investigation Efforts Becoming Increasingly More Important


While testing for PFAS in water sample matrices captures most of the attention, the analysis of soil for PFAS is growing in importance. Environmental scientists are working hard to identify and investigate the presence of PFAS contamination in soil.  Soil site investigation efforts are increasing in importance as regulatory agencies and communities are looking to identify the sources of PFAS contamination. 

National SSEHRI PFAS Contamination Site Tracker Now Includes 28 Michigan Sites - Most of Any State

National SSEHRI PFAS Contamination Site Tracker Now Includes 28 Michigan Sites - Most of Any State

In May, we shared with you information about a national PFAS contamination site tracker being maintained by Northeastern University’s Social Science Environmental Health Institute (SSEHRI).  At the time, there were 17 sites in Michigan on the SSEHRI PFAS Contamination Site Tracker list.  In just four months, the number has increased to now include 28 Michigan sites with PFAS contamination.
