Toxic PFAS Leach Through Most In-Home Drinking Water Filters

  Filters on refrigerator doors, pitcher-style filters, and whole-house filtration systems might function differently overall, but they have one thing in common: they might not be removing all toxic drinking water contaminants. Toxic PFAS, dubbed “forever chemicals,” persist in the environment indefinitely and accumulate in the human body. 99.9 percent of humans worldwide have PFAS in their bloodstreams.   Duke and North Carolina State University scientists found that most filters are only partially effective in removing PFAS. Research suggests that several filters, if not properly maintained, can lead to even higher levels. PFAS have known health impacts and are a widespread presence in the environment, especially in drinking water. Exposure to these toxic chemicals is associated with various cancers, low birth weight in babies, thyroid disease, impaired immune function, and other health disorders. PFAS can also affect reproductive and developmental health in mothers and children.

Ann Arbor’s Gelman Dioxane Plume to be Remediated in Landmark Agreement

  Local officials in Ann Arbor announced a proposed settlement after years of fighting in court for better cleanup of the Gelman Dioxane Plume . A more aggressive plan includes thorough monitoring of the plume’s expansion through the city’s groundwater and treating pollution at the source. Gelman Sciences is to blame for the polluted water. Washtenaw County Board Chairman Jason Morgan said, “This is a monumental moment in our 40-plus-year effort to clean up the Gelman dioxane plume. We finally have a new proposed consent judgment and have made the documents public. This is a big deal.” Polluter Gelman Sciences would be required to install new groundwater extraction wells to remove dioxane pollution from the environment, as well as more monitoring wells to further investigate the migration of the toxic chemical, with new trigger levels for taking action. They would also be required to install two new remediation techniques to increase removal of dioxane in the ground at the source
