This week: Worrisome PFAS Levels Found in Drinking Water Supplies from Lake Erie + Oil Pipeline Denied Water Certification + Plastics as Part of Our Geology

Worrisome PFAS Levels Found in Drinking Water Supplies from Lake Erie

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.

Oil Pipeline Denied Water Certification

An application to upgrade a pipeline (Line 3 owned by Enbridge) that crosses through the upper Great Lakes region was denied a needed certificate for failing to adequately plan for a spill in Lake Superior.  The company will meet with the Minnesota Pollution Control Agency to review what is needed to comply with the environmental review.  

Plastics as Part of Our Geology

Future geologists won’t just be looking at rocks but plastics too. A recent study found an abundance of microplastics in sand and sediment.  Patricia Corcoran and her students at the University of Western Ontario are studying microplastics in sediment samples from Lakes Huron, Ontario, Erie and St. Clair and how they are becoming part of the geology.  They found that rivers and streams are the primary pathways for the microplastics and higher concentrations were generally associated with river mouth areas.


PFAS Test Kits – GIFT a KIT!
Freshwater Future believes everyone has a right to know what is in their drinking water, regardless of what’s in their wallets. We have partnered with the University of Michigan Biological Station and other donors to offer PFAS testing for homes on private wells at reduced rates. You can help make our kits even more accessible by selecting Gift a Kit at check out. We’ll use your donation to send a kit to someone else as part of our “Pay What You Can Program”. Get (or gift) your test kits today!
