Are you concerned about PFAS in Michigan’s drinking water?

June 1, 2018

Michigan is home to the largest supply of fresh water in the world. Unfortunately, Michigan received national attention a few years ago for lead contamination in a municipal drinking water supply. Now, news agencies are reporting on PFAS (per- and poly-fluoralkyl substances) identified in several drinking water sources throughout Michigan.

What should you do?

Be aware of the issue, stay calm, and understand the science.

The EPA and MDEQ are working on establishing acceptable limits for PFAS. Laboratory testing equipment now enables detection of PFAS in drinking water at parts per TRILLION (PPT). What is a one in a trillion? To grasp this minute measurement used for trace detections in drinking water, here are a couple of analogies to consider:

  • The State of Michigan (upper and lower peninsula) is about 3 trillion square feet. If it was covered entirely with 12-inch floor tiles, 3 of these tiles would represent 1 part-per-trillion.
  • One part-per-trillion is equal to one second in 31,500 years.

The MDEQ is currently working to sample and test all public water systems for PFAS. The State of Michigan is also requiring all municipal waste water treatment plants with Industrial Pretreatment Programs to sample and test the waste water discharge from industries suspected of containing PFAS by June 29, 2018.

You can also proactively have a trained technician sample and certified laboratory test your water supply and/or your wastewater discharge. The procedures for sampling for accurate PFAS testing are very strict and continually improving. Prein&Newhof has several technicians trained to properly collect drinking water and waste water samples for PFAS testing. We are working toward getting certified for PFAS testing at our laboratory in Grand Rapids.
