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 ...
Remediation of per- and polyfluoroalkyl substances refers to the destruction or removal of per- and polyfluoroalkyl substances (PFASs) from the environment. PFASs are a group of synthetic organofluorine compounds, used in diverse products such as non-stick cookware and firefighting foams, that have attracted great concern as persistent organic pollutants.
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 ...
MPART is a multi-agency team tasked with investigating PFAS contamination sites and sources in the state, protecting drinking water, enhancing interagency communication and keeping the public informed. [183] In January 2018, Michigan established a legally enforceable groundwater cleanup level of 70 ppt for both PFOA and PFOS.
Of those, 982 were identified as contaminated with PFAS compounds, with 299 having detections of total PFAS over 70 parts per trillion, the EPA's previous lifetime health advisory level set in ...
Other states that have issued PFAS standards include Michigan, New York and Vermont. [79] Between 2016 and 2021 the U.S. Geological Survey (USGS) tested tap water from 716 locations across the United States, finding PFAS levels exceeding the EPA advisories in approximately 75% of samples from urban areas and in approximately 25% of rural areas ...
In 2020 the Michigan Department of Environment, Great Lakes, and Energy (EGLE) adopted stricter drinking water standards in the form of maximum contaminant levels (MCLs), lowering acceptable levels from the 2018 enforceable groundwater cleanup levels of 70 ppt to 8 ppt for PFOA and 16 ppt for PFOS and adding MCLs for 5 previously unregulated ...
In the years between 1999–2000 and 2003–2004, the geometric mean of PFNA increased from 0.5 parts per billion to 1.0 parts per billion in the US population's blood serum. [ 14 ] and has also been found in human follicular fluid [ 15 ] In a cross-sectional study of 2003–2004 US samples, a higher (13.9 milligram per deciliter ) total ...
