New, enforceable state drinking water standards to protect public health from seven toxic compounds will take effect early this month.
“Michigan is once again leading the way nationally in fighting PFAS contamination by setting our own science-based drinking water standard,” Michigan Gov. Gretchen Whitmer said.
Called for by Gov. Whitmer last year, the standards set maximum limits for the seven PFAS compounds. Known as “forever chemicals” because they break down slowly in the environment, PFAS have emerged as a national issue as more and more contamination sites are found. Two of the most serious hotspots in Michigan are sites associated with Wolverine Worldwide in Kent County and the former Wurthsmith Air Force Base in Iosco County.
“It is imperative for Michigan to promulgate the proposed rules as soon as practicable,” said FLOW Executive Director Liz Kirkwood. “Testing continues to turn up new sites of PFAS contamination in Michigan, many of them exposing citizens to substantial health risks. Federal rules are likely years away and may not provide the level of protection that the people of Michigan want and need for public health and the environment.”
The standards apply to approximately 2,700 public drinking water supplies across the state and will be enforced by the state Department of Environment, Great Lakes, and Energy (EGLE). FLOW and other organizations have strongly supported the state standards in the absence of binding, enforceable drinking water standards set by the U.S. Environmental Protection Agency.
PFAS have been used in thousands of applications globally, including firefighting foam, food packaging, non-stick coatings, stain and water repellents, and many other consumer products. PFAS compounds have been linked in scientific studies to:
- Reducing a woman’s chance of getting pregnant
- Increasing the chance of high blood pressure in pregnant women
- Increasing the chance of thyroid disease
- Increasing cholesterol levels
- Changing immune response
- Increasing the chance of cancer, especially kidney and testicular cancers.
“Governor Whitmer and EGLE deserve tremendous credit for taking this important first step in protecting Michigan residents from PFAS in their drinking water,” said Cyndi Roper, Michigan Senior Policy Advocate for the Natural Resources Defense Council. “Michigan is now regulating seven PFAS chemicals—which is more than any other state—and two of the standards are the nation’s most health protective. However, several of the new PFAS standards should have been more health protective based on the existing science.”
Roper added: “Further, even if we set standards for seven PFAS chemicals each year, it would take far too many generations to protect residents from the health impacts of these chemicals. Instead of playing regulatory whack-a-mole, Michigan should set a treatment technique that is most effective at cleaning up all known PFAS from drinking water.”
PFAS present a significant risk to human health. They break down slowly in the environment, can move quickly through the environment, and are associated with a wide array of harmful human health effects including cancer, immune system suppression, liver and kidney damage, and developmental and reproductive harm.
