Beginning August 3, Michigan’s New Drinking Water Standards Re: PFAS

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) recently announced that the state will soon implement strict regulations to limit PFAS (per- and polyfluoroalkyl substances) contamination in drinking water. After a year-long review by the Michigan PFAS Action Response Team (MPART), it was determined that Michigan must set new drinking water standards for public water systems to achieve. This ruleset will limit seven PFAS chemicals in drinking water—exceeding the U.S. Environmental Protection Agency’s current guidelines. It will also have an immediate effect on Michigan’s existing groundwater clean-up criteria.

This new ruleset is expected to take effect on August 3, 2020.

Prein&Newhof’s Environmental Laboratory in Grand Rapids has the capacity to test for 18 PFAS compounds in drinking water using EPA 537.1 method, which includes these seven PFAS chemicals in the ruleset. We can also test for 28 PFAS compounds in groundwater and wastewater using a modified EPA533 method, which also includes these seven PFAS compounds. If you are a public water supplier, we can help you test for PFAS, determine the results, and implement any changes if necessary.
