The Michigan Department of Environment, Great Lakes, and Energy introduced some of the strictest drinking water standards in the country for PFAS, setting maximum contaminant levels (MCLs) for PFOA and PFOS to 8 and 16 ppt respectively (down from previous existing groundwater cleanup standards of 70 ppt for both), and introducing MCLs for five ...
One of twenty deer tested near Clark's Marsh was found to have a PFOS level of 547 parts per billion (ppb) taken from a muscle sample. It is unknown how PFAS could accumulate to the level seen in the deer found near Clark's Marsh. All deer except the one with elevated levels at Clark's Marsh were found to have no or very low levels of PFAS ...
For example, Minnesota recommends a guidance value of 0.027 μg/L for PFHxS, [23] and Michigan has a screening level of 0.084 μg/L for PFHxS. [4] In 2020, Michigan adopted drinking water standards for 5 previously unregulated PFASs including PFHxS, which has a maximum contaminant level (MCL) of 51 parts per trillion (ppt) or 0.051 μg/L.

Nearly 35 million people get their water from systems that reported high levels of PFAS in at least one test last year. Fixing the problem is costly. More than 600 water systems reported PFAS ...
If PFAS levels are concerning, consumers can purchase an under-the-counter water filter for their tap. NSF, formerly the National Sanitation Foundation, has a list of recommended filters.
Studies have shown that the chemicals have been linked to reproductive and developmental problems as well as cancerous tumors.
In 2020 Michigan adopted drinking water standards for 5 previously unregulated PFAS compounds including HFPO-DA which has a maximum contaminant level (MCL) of 370 parts per trillion (ppt). Two previously regulated PFAS compounds PFOA and PFOS had their acceptable limits lowered to 8 ppt and 16 ppt respectively. [26] [27]
Mar. 7—National and state officials are zeroing in on the West Plains as PFAS well-testing begins this week. Speaking from the center of the exposure in Airway Heights, EPA Regional ...
