December Green Drinks - PFAS in Iowa: The prevalence of “Forever Chemicals” in Iowa's Aquifers, Surface Waters, and Drinking Water
Tuesday, December 6th at 5:00 pm via Zoom
Environmental Forum
Speaker: Matthew Graesch, Environmental Specialist, Iowa Department of Natural Resources
The “forever chemicals”, or PFAS (per- and polyfluoroalkyl substances), are a class of potentially toxic and highly persistent chemicals widely used in commercial products and industrial processes. For the past 3 years, Matthew has been working to better understand the extend of PFAS contamination in Iowa. He designed and implemented a surveillance program to test our drinking water supplies. More than 600 water samples from the aquifers and surface waters were analyzed for 25 different PFAS compounds. By the time this study concludes next spring, drinking water of over 75% of Iowans will have been tested for PFAS compounds.
Matthew will discuss with us where PFAS originate, why they are problematic, and how they are regulated. He will also review the results from the surveillance program, how PFAS chemicals affect our water sources and how to identify effective treatment to remove them from our drinking water.
