The next phase of statewide PFAS surveillance testing is slated to begin in May 2019 and run through October 2019. This effort will sample non-community public water supplies which were not part of Phase I, to assess the potential for PFAS impact in drinking water for expanded at-risk populations. Testing will be conducted for the following non-community supplies utilizing their own well or wells:
In addition, Phase II will sample two more Type I community water supplies that were not available during Phase I. All Phase II sampling results will be provided on this page, once they are available.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has provided recommendations based on PFAS levels. Download this notification protocol (pdf).

Understanding the Sample Results
Definitions of the information provided in the sampling results tables:
*Results are provided in parts per trillion. A part per trillion (ppt) is the equivalent of 1 drop of water in 20 Olympic-size swimming pools
