PFAS regulations develop for Michigan drinking water and fish consumption

Clifford Yantz, PG

Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic compounds considered as emerging contaminants. PFAS are manufactured for use in many applications, from firefighting foam to food packaging and many other consumer and industrial products. PFAS are ubiquitous in the environment, and there currently is a lack of scientific and regulatory consensus on the toxicological risk associated with drinking water or consuming fish that contains PFAS.

In late 2017, the State of Michigan began developing and directing a multi-agency effort intended to identify PFAS sources, as well as exposure risks to its citizens. In February 2018, the Michigan Department of Environmental Quality (MDEQ) commenced an Industrial Pretreatment Program (IPP) PFAS source investigation and elimination initiative requiring wastewater treatment plants to investigate their industrial wastewater permit holders. After establishing the IPP PFAS program, MDEQ began a Public Water Supply survey designed to analyze for PFAS in over 1,300 drinking water sources that were not previously tested during the Third Unregulated Contaminant Monitoring Rule (UCMR3). Additional PFAS investigations are likely to occur in 2018 for other potential sources.

OBG presents in Michigan on PFAS

On June 13, 2018, Clifford Yantz, PG and John Newsted, PhD presented at a luncheon event hosted by the Society of Military Engineers (SAME) Detroit Post. In this presentation, Clifford provided an overview of PFAS compounds, historical uses and sources, special sampling and analysis requirements, and remedial options. John presented his research on perfluorooctane sulfonate (PFOS) uptake by various fish species in Michigan rivers, and provided a comparative analysis of the fish consumption advisories issued in several states.
