Two municipal drinking water systems in Michigan, Monroe and Frenchtown test results found PFOS at 16 parts per trillion (ppt) and 15 ppt, respectively.  The Michigan Department of Health and Human Services set a health screening level of 8 ppt for PFOS in April. The water intakes for these systems are in Lake Erie near the mouth of the Huron River and the River Raisin.

Indiana University to Test for PFAS in Rain

Researchers at Indiana University will be monitoring the amount of PFAS in rain and snowfall. The Integrated Atmospheric Deposition Network at the University has a long history of studying persistent chemicals and will now add this pollutant to their protocol. This will help us  understand how much of these chemicals is being deposited into our lakes and streams and eventually making their way into our drinking water and food.
